How to reduce housekeeping chemical consumption and cost per use

15 Oct 2026 · 6 min read

Housekeeping chemical budgets in hotels, hospitals, offices and facility management contracts often rise without any change in the area being cleaned. The cause is rarely the price of the product. It is usually how much product is used each time, and whether the right product is used for the task.

The useful measure is cost per use: the cost of the solution that actually goes onto a floor, bathroom or glass surface, not the price per litre of concentrate. A concentrate that looks expensive per litre can be economical per use when it is diluted correctly, and a cheap product can be costly when staff pour it freely.

This guide covers the practical controls that bring consumption down and keep cleaning results consistent.

Start with concentrates and cost per use

Concentrated products are diluted with water at the point of use, so you buy, store and transport less. Most Evochem housekeeping products carry a label dilution; for example EVO 2 hard surface cleaner and EVO 7 neutral floor cleaner are both 2% to 5% (20 ml to 50 ml in 1 litre of water) depending on soil, and EVO 3 glass cleaner concentrate is 2% to 10% (20 ml to 100 ml in 1 litre of water). To compare products fairly, work out the cost of one litre of ready-to-use solution at the dilution you actually need.

• EVO 2Hard Surface CleanerPowerful and routine cleaning solution with our non-abrasive hard surface cleaner, carefully formulated to be slightly alkaline and safe for use on all types of hard surfaces, from floors and walls to countertops and fixtures, making it the perfect choice for maintaining a clean and pristine environment.
• EVO 7Neutral Floor CleanerVersatile and effective cleaner suitable for both manual and machine-based cleaning methods. Our neutral pH formula effectively removes dirt and grime without leaving unwanted residues or marks. Suitable for daily maintenance.
• EVO 3Glass Cleaner ConcentrateGet a crystal-clear shine on windows, mirrors, and glass surfaces with our potent and gentle cleaner, which effectively removes dirt, dust, fingerprints, and haze without leaving residue, making it perfect for delicate surfaces and everyday cleaning needs.

Measure every dilution

Free pouring, “a splash in the bucket”, is the main cause of waste. It also tends to over-strength solutions, which leave residue on floors and glass and then need extra rinsing. Cleaning chemical dilution control simply means the same measured quantity goes into the same volume of water every time.

1. Fix the bucket, trigger bottle and machine tank sizes used in each area.

2. Calculate the chemical quantity for each container at the label dilution.

3. Provide measuring jugs, pump tops or a dispenser so staff do not estimate.

4. Label each refilled bottle with the product name and dilution.

5. Display a simple dilution chart in the janitor room.

Use dosing equipment where volume justifies it

• Wall-mounted dilution dispensers fill buckets and bottles at a fixed ratio from the concentrate drum.

• Pump tops on 5 L cans deliver a set volume per stroke.

• Dosing pumps on dishwashers and laundry machines remove guesswork completely.

• Bulk packs of 20 L, 50 L or 200 L reduce packaging and the cost of frequent small purchases when paired with a controlled dispensing point.

Colour-coding and the right product for each task

Using one strong product everywhere wastes chemical and can damage surfaces. A descaler is not needed for daily glass cleaning, and a degreaser is not needed on a carpeted office corridor. Match each product to the task and colour-code cloths, mops and buckets by area so products and tools are not mixed between washrooms, kitchens and general areas.

• Daily washroom cleaning: a bathroom cleaner such as EVO 1; keep a heavy-duty descaler such as EVO 9 for periodic deep cleaning.

• Floors: a neutral floor cleaner for daily maintenance; a degreaser only where grease is present.

• Glass and mirrors: a glass cleaner concentrate at the lower end of its dilution for light soil.

• EVO 1Bathroom CleanerPowerful bathroom cleaner uses organic acid to cut through tough stains like dirt, soap scum, and lime deposits on porcelain, plastic, and stainless steel surfaces. It also removes hard water scale and lime buildup, making it ideal for frequently used restrooms.
• EVO 9Heavy Duty DescalerPotent descaling solution that is highly effective in dissolving and eliminating tough scale and scum buildup on tiles and ceramics. Evo 9 can be used as a deep cleaner once in a while and can be used daily with higher concentration.

Avoid over-strength use

Staff often believe a stronger mix cleans better. In practice, excess detergent leaves a film that attracts dirt, dulls floors, makes them slippery and creates streaks on glass, so the area needs cleaning again sooner. Use the lower end of the label range for routine soil and the upper end only for heavy soil.

Over-strength use also shortens the life of mops, pads and machine parts, and some residues need an extra rinse to remove, which costs labour and water as well as chemical. Supervisors should treat a strong chemical smell in a corridor or washroom as a sign that dilution needs checking.

Train, monitor and review

1. Train every new staff member on dilution, the product for each task and safe handling; refresh training regularly.

2. Issue concentrate from one controlled point and record what goes out to each floor or site.

3. Compare consumption against the area cleaned each month and look into sudden changes.

4. Check results on the floor, not only the stock sheet: under-dilution shows up as poor cleaning.

5. Ask our team for on-site dilution guidance and training when you change products or staff.
