Dry Cleaning, Laundry Services, Laundromats Industry Terminology

Alkali Builder

A laundry chemistry additive (e.g., sodium carbonate, silicate, or phosphate alternatives) that increases wash-bath pH to enhance detergency, saponify fats, and buffer water hardness. Often paired with surfactants, enzymes, and sequestrants; must be neutralized in a final sour to prevent fabric damage.

We boosted alkalinity with a builder to saponify body oils on towels; High builder dosage raised pH too much—add sour in the final rinse; Switch to a phosphate-free builder to meet local discharge limits.

Average Order Value (AOV)

A revenue metric showing the average spend per transaction (total revenue divided by number of orders). Helps evaluate pricing, bundling, and upsell strategies for services like wash-dry-fold and pickup-and-delivery.

Our PUD AOV rose from $38 to $46 after adding express service; Bundle pricing increased AOV without hurting churn; Track AOV by zip code to refine delivery zones.

Barrier Washer

A pass-through washer with separate loading (soiled) and unloading (clean) sides that physically separate dirty and clean areas to reduce cross-contamination. Common in healthcare, cleanrooms, and high-hygiene OPLs.

Install barrier washers for the long-term care wing to meet infection control; The pass-through design prevents soiled and clean traffic from crossing; We spec’d 60-pound barrier units for the hospital OPL.

Boiler Blowdown

The periodic removal of water from a steam boiler to control total dissolved solids, prevent foaming/carryover, and limit scaling/corrosion. Often paired with heat recovery to improve energy efficiency.

Automate surface blowdown to control TDS and prevent scale; Schedule bottom blowdown daily to remove sludge; Blowdown heat recovery cut our gas bill by 6%.

Card System (Laundry Payment)

Cashless payment platforms for laundromats and OPLs, including stored-value cards, credit/debit acceptance, and mobile wallets. Enable dynamic pricing, loyalty, remote monitoring, and lower coin-handling costs.

We converted from coin to a hybrid card/mobile system; Card readers enable vend price changes by time-of-day; EMV-compliant card kiosks reduced chargebacks.

Continuous Batch Washer (CBW)

An industrial tunnel washer comprising multiple modules for sequential processing (pre-wash, wash, rinse, etc.). Items move counter-current to water flow for high water/energy efficiency and consistent quality.

The new CBW increased throughput to 4,000 lbs/hour; We tuned the modules for heavier soil on kitchen linens; CBW plus press and shuttle feeds the ironers continuously.

Customer Acquisition Cost (CAC)

The average marketing and sales cost required to acquire one new customer. Used alongside lifetime value to evaluate profitability of channels such as digital ads, direct mail, or partnerships.

Our CAC on Google Ads is $18 for WDF customers; Route partnerships lowered CAC in new suburbs; Compare CAC to LTV before scaling delivery.

Dry-to-Dry Machine

A dry cleaning machine that completes washing, extraction, and drying in one sealed unit without transferring garments. Improves solvent containment, reduces labor, and lowers fugitive emissions.

The dry-to-dry perc unit eliminated transfer handling; Cycle includes wash, extract, and dry in a closed system; Switching to hydrocarbon dry-to-dry reduced solvent loss.

Emulsifier

A chemical that disperses oils/greases into water or solvent, enabling removal during washing. Often used with surfactants to handle fatty soils in both wet and dry processes.

Add an emulsifier to break up salad oil stains; Protein stains improved once we balanced emulsifier with enzymes; Use solvent-compatible emulsifiers in drycleaning.

Environmental Protection Agency (EPA) NESHAP

Federal National Emission Standards for Hazardous Air Pollutants regulating emissions (notably perchloroethylene) from dry cleaning plants. Includes equipment standards, leak checks, recordkeeping, and reporting.

Ensure perc machines comply with NESHAP leak inspection rules; Recordkeeping is required under the drycleaner NESHAP; We transitioned away from PCE to simplify NESHAP compliance.

Extract G-Force

A measure of centrifugal force during spin extraction in washer-extractors, expressed as multiples of gravity (G). Higher G reduces residual moisture and dryer time but can stress fabrics or mechanics.

300 G extraction cut dryer time by 20%; Higher Gs risk creasing on delicates; Compare extract G across washers to balance loads.

Flatwork Ironer

Large finishing equipment that dries and presses flat linens (sheets, tablecloths) using heated rolls or chests. Often paired with feeders, folders, and stackers for continuous, high-volume finishing.

Run sheets on the 130-inch ironer at 40 m/min; Steam chest temperature is too low—check boiler; Auto-folder downstream of the ironer boosted productivity.

Gallons per Pound (Water Factor)

A metric indicating water consumption relative to load size. Lower numbers indicate higher efficiency; tracked to control utility costs and environmental impact.

Our new washers run at 1.8 gal/lb; Lower water factor reduced sewer fees; Delicate cycles increase water factor for rinsing.

GreenEarth (D5 Silicone Solvent)

A branded dry cleaning process using decamethylcyclopentasiloxane (D5) silicone solvent. Valued for gentleness, low odor, and certain regulatory advantages versus perc; requires specific machines and detergents.

We switched to GreenEarth to market gentler cleaning; D5 is compatible with many trims that fail in perc; Verify waste handling for silicone solvent still bottoms.

Heat Recovery System

Technologies that reclaim waste heat from dryers, boilers, and wastewater to reduce gas/electric consumption. Includes air-to-air exchangers, condensate return, and wastewater heat recovery.

We capture dryer exhaust heat to preheat makeup air; Plate heat exchangers reclaim heat from boiler blowdown; Return condensate to the boiler to save energy.

Hydrocarbon Solvent

Petroleum-based dry cleaning solvents (e.g., DF-2000, K4) with higher flashpoints and gentler action than perc. Require compatible machines, longer cycles, and careful fire safety management.

K4/HCS solvent reduced dye bleed vs perc; Longer cycle times with hydrocarbons require planning; Check flashpoint and ventilation specs.

Ion Exchange Water Softener

Equipment that removes hardness ions (calcium, magnesium) from incoming water, typically via sodium ion exchange. Improves detergency, reduces scaling, and stabilizes wash chemistry.

Hardness spiked—regenerate the softener; Soft water improved detergent performance and reduced scale; Use separate brine tank and schedule salt deliveries.

Job Ticketing

The system for identifying, routing, and tracking individual items or orders through cleaning and finishing. Often uses barcodes/RFIDs and integrates with POS for status updates and billing.

Use barcodes on tickets for piece-level tracking; Ticket notes flag stains and repairs; Integrated ticketing with POS cut lost garments.

Lockout/Tagout (LOTO)

Safety procedures to de-energize and lock out equipment during maintenance or repair. Prevents accidental energization and injuries; required under OSHA standards.

LOTO the dryer before servicing the belt; Only authorized staff may remove a lock; Our LOTO audit found missing tags on the press.

Make-up Air

The fresh air supplied to replace air exhausted by dryers and ventilation. Adequate makeup air is essential for combustion safety, drying performance, and indoor air quality.

Insufficient makeup air is causing long dry times; Size louvers to meet dryer CFM requirements; Cross-drafts near the ironers indicate airflow imbalance.

Material Safety Data Sheet / Safety Data Sheet (SDS)

Standardized documents detailing chemical hazards, handling, storage, and emergency measures. SDSs are required for all solvents, detergents, and maintenance chemicals on site.

Check the SDS for PPE and first-aid guidance; Keep SDS binders accessible on the plant floor; Vendors must provide updated SDS for new detergents.

Neutralizer / Laundry Sour

An acidic chemical added in the final rinse to neutralize residual alkalinity, optimize pH, prevent fabric damage, and improve hand/whiteness. Common acids include acetic and citric.

Add sour to bring pH down after a heavy-alkali wash; Yellowing on linens improved with proper souring; Use citric acid-based sours for eco programs.

On-Premise Laundry (OPL)

Laundry operations located within institutions (hotels, hospitals, nursing homes) that process their own linens. Emphasize reliability, hygiene, and cost control.

The hotel OPL processes 1,200 lbs/day; OPL gives tighter linen inventory control; Decide between OPL investment or outsourcing to a route plant.

Optical Brightener

Fluorescent whitening agents that absorb UV and emit blue light, enhancing perceived whiteness and brightness. Used in detergents for whites; can affect color matching and lighting appearance.

Adding OBAs made whites pop under LED lighting; Avoid OBAs on rental textiles that must match; OBAs can mask, not fix, residual graying.

Perc (Perchloroethylene, PCE)

A chlorinated solvent historically dominant in dry cleaning. Highly effective but regulated due to health and environmental concerns; requires containment, vapor recovery, and strict compliance.

Perc machines require NESHAP leak checks; We phased out perc due to local air rules; Perc excels on oily soils but watch trim compatibility.

Pickup and Delivery (PUD)

Logistics service collecting and returning customer garments or laundry. Relies on route planning, time windows, and customer communication to scale profitably.

Expanding PUD added 30 stops per route; Optimize PUD windows by clustering orders; We offer PUD subscriptions to stabilize demand.

Point of Sale (POS)

The software/hardware system that manages sales, payments, inventory, customer profiles, and reporting for dry cleaners and laundromats. Often integrates with card systems and delivery apps.

Our POS integrates with ticketing and SMS updates; Use POS to track promos and tender types; POS flag warns when a piece has repeat stains.

Preventive Maintenance (PM)

Planned servicing of equipment (washers, dryers, presses, boilers) to prevent failures, improve safety, and extend lifespan. Typically scheduled by time or usage metrics.

Monthly PM reduced unplanned dryer downtime; Include steam trap testing in PM checklists; Use CMMS to schedule PM by run-hours.

Residual Moisture Content (RMC)

The percentage of water remaining in textiles after extraction. Lower RMC shortens dryer or finishing time and reduces energy use; target varies by fabric and downstream process.

Aim for 45% RMC before the tunnel finisher; High RMC is bottlenecking dryers; Increase G-force to lower RMC on towels.

Reverse Osmosis (RO)

A water purification process that removes dissolved solids and contaminants using semi-permeable membranes. Produces consistent water quality, improving chemistry control and finish.

RO supply reduced spotting on glassware towels; Blend RO with softened water to manage TDS; RO helps wet cleaning in high-mineral areas.

Route Density

The concentration of stops within a delivery route area. Higher density reduces drive time per order, improving labor efficiency, fuel costs, and on-time performance.

Increase route density to lift PUD margins; We trimmed low-density zip codes; Cluster marketing to improve stop density.

Sequestrant / Chelant

Chemicals that bind calcium, magnesium, and metal ions in water and soils, preventing scale, graying, and interference with detergents/bleaches. Common types include phosphonates and biodegradable chelants.

Add EDTA alternative to bind hardness ions; Chelation prevented scale in the steam lines; Sequestrants enhance bleach stability.

Shirt Finisher (Tensioning Unit)

Finishing equipment that dries and presses shirts using steam, hot air, and controlled tension. Provides consistent shape and reduce labor compared to manual pressing alone.

The tensioning unit improved sleeve crease quality; Adjust body tension to avoid shine; Feed sequence: collar-cuff press then shirt finisher.

Solvent Recovery Still

A distillation unit within a dry cleaning system that purifies used solvent by boiling off contaminants. Maintains cleaning quality and reduces solvent purchases and waste.

Distill solvent nightly to remove fats and dyes; Monitor still bottoms disposal as hazardous waste; Clean the still to maintain distillation rates.

Spotting Board

A workstation for stain identification and treatment before or after the main cleaning cycle. Equipped with steam/air guns, vacuum, and chemical trays for targeted stain removal.

Pre-spot tannin stains with steam assist; Use protein spotter then flush at the board; Ventilation at the spotting board protects techs.

Spontaneous Combustion Risk

The hazard that inadequately dried, oil-laden textiles can self-heat and ignite, especially when balled up post-dryer. Mitigated by proper wash chemistry, full drying with cooldown, and safe storage.

Oily kitchen rags must cool before bagging; Run a cool-down phase and unload promptly; Provide metal bins with lids for oily textiles.

Steam Trap

A valve that removes condensate and non-condensable gases from steam lines while preventing steam loss. Critical for heat transfer efficiency and protecting equipment from water hammer.

Failed traps caused water hammer at the ironer; Test traps annually to prevent energy loss; Inverted bucket traps suit dirty steam.

Surfactant

Surface-active agents that lower surface tension, wet fabrics, and help lift and suspend soils. Categories include anionic, nonionic, cationic, and amphoteric; chosen based on fabric and soil type.

Anionic surfactants improved particulate soil removal; Low-foaming surfactants suit high-extract washers; Use solvent-compatible surfactants in hydrocarbon cleaning.

Throughput (Turns per Day)

A measure of production output over time. In laundromats often discussed as turns per day per machine, while in plants it may be pounds per hour or pieces per hour across process steps.

We modeled throughput by hour to staff the attendants; Ironer line throughput is the plant’s bottleneck; Raising vend prices flattened low-value throughput on weekends.

Tunnel Finisher

A continuous conveyor system that dries and de-wrinkles garments using steam and hot air, reducing or replacing manual pressing. Works best with controlled RMC and proper loading.

Send polos through the tunnel finisher at 40% RMC; Adjust dwell time for heavier knits; Tunnel finishing reduced manual pressing by 60%.

Turns per Day (TPD)

Key laundromat metric: the average number of cycles a machine runs per day. Indicates equipment utilization, guiding pricing, marketing, and capacity planning.

Our 60-lb washers average 4.2 TPD; TPD jumped after we added mobile pay; Optimize machine mix to lift TPD in peak windows.

Utility Press

Versatile steam press with a flat head and buck used for finishing various garments. Variants include leggers and specialized presses for collars/cuffs.

Use the utility press for jackets and slacks; Steam leaks on the hot head lowered quality; Train operators on pad maintenance for crisp finishes.

Vend Price

The posted price customers pay per machine cycle in a laundromat. Managed dynamically based on capacity, competition, and utility costs.

We raised the 40-lb washer vend to $5.75; Use time-of-day pricing to balance demand; Vend changes are easy with the card system.

Volatile Organic Compounds (VOCs)

Organic chemicals that readily vaporize, contributing to indoor air quality concerns and smog formation. Regulated in many jurisdictions; relevant for spotters, solvents, and adhesives.

Select low-VOC spotters for better IAQ; Local rules cap VOCs in cleaning agents; Ensure ventilation meets VOC exposure limits.

Wash-Dry-Fold (WDF)

Retail bulk laundry service where the operator washes, dries, and folds customer laundry, typically priced per pound with optional add-ons (spotting, hang-dry, hypoallergenic).

Our WDF turnaround is 24 hours; Charge WDF per pound with tiered pricing; Offer add-ons like hypoallergenic WDF.

Washer-Extractor

Commercial/industrial washing machines that both wash and spin-extract water from textiles. Available in hard-mount and soft-mount designs with programmable controls.

The 80-lb extractor hits 350 Gs; Soft-mount machines simplified installation; Program multiple baths for heavy soil.

Wastewater Pretreatment

Processes and equipment that condition effluent before discharge to sewer, including screens, lint traps, oil/grease interceptors, pH adjustment, and flow control to meet local regulations.

Install lint and grease interceptors to meet discharge permits; Automatic pH neutralization before sewer; Sampling ports are required for inspections.

Wet Cleaning

Professional water-based garment cleaning using programmable machines, specialized detergents, and finishing to safely process items traditionally dry cleaned. Emphasizes fiber-safe mechanics and chemistry.

Use controlled agitation and eco detergents for wool in wet cleaning; Wet-clean that beaded dress only if trim is water-safe; Wet cleaning reduced our reliance on solvents.

Workflow Balancing

Operations method to distribute work evenly across process steps and labor to avoid bottlenecks and idle time. Improves throughput, quality, and labor productivity.

Pressing fell behind—rebalance labor from sorting; Line balancing around the ironer boosted OEE; Use takt time to balance CBW modules and finishing.

Zoning and Permitting

Local regulatory approvals needed to open and operate a facility, covering land use, building codes, mechanical/electrical/plumbing, air emissions, signage, and occupancy.

Confirm zoning allows coin-operated laundries; Air district permits required for solvent machines; Build-out permits delay opening by 6 weeks.
