How to Use an Industrial Degreaser Concentrate: Dilution and Application Guide

The product label or technical data sheet sets the ratio — concentrates run from 1:256 for light soil up to 1:10 for heavy soil.

A five-gallon pail either saves a maintenance budget or strips a floor finish, and the difference is usually a measuring cup. Concentrates ship at full strength so you add the water yourself, and pouring an industrial degreaser concentrate straight from the pail is how most surface damage starts.

Two things get settled before any bottle is filled: which product you actually have, and how dirty the surface is. Everything below follows that order — ratio first, then dispensing limits, then mixing and rinsing.

Diluting An Industrial Degreaser Concentrate: What Decides The Ratio

Soil level and surface type set the ratio, and only the label or technical data sheet for your specific product can tell you what it is. Ratios are not interchangeable between brands, and they are not a suggestion.

EP67 Heavy Duty Industrial Degreaser, sold under product code 101106667 in four 1-gallon containers or a 5-gallon pail, publishes a spread wide enough to show why guessing fails: 1:256 for light-duty soils down to 1:10 for heavy-duty soils. That same product covers light-duty tabletops at 1:256 and kitchen floors at 1:167, so the number moves with the job rather than with your patience.

• Measure concentrate and water separately. A splash poured by eye turns a 1:64 batch into something closer to 1:10.
• Add water to the container first when the manufacturer specifies it. EP67’s instructions call for water first to reduce foaming, then the concentrate.
• Use cold water where required. EP67 specifies cold water, and a warm batch foams harder while landing at the wrong strength.
• Write the product name and ratio on every secondary bottle. Unlabeled sprayers are how a heavy mix ends up on a laminate counter.

The published EP67 chart, plus the one dispenser-only exception worth knowing about:

Ranges cover two working strengths, not one. Start at the weaker end and step up only if the soil does not lift.

Why Do Some Concentrates Require A Dispenser?

Some concentrates are locked to proprietary dispensing equipment, which means hand-measured dilution is not an option the manufacturer allows.

3M Industrial Degreaser Concentrate 26A must be diluted and dispensed only through the 3M Flow Control System Wall Mount Dispenser or the portable version of that system. The 26H and 26L formats must go through the 3M Twist ’n Fill Cleaning Chemical Management System, and the technical document does not authorize manual dilution for any of the three. 3M’s industrial degreaser technical data spells the requirement out directly.

Read that as a hard condition, not a sales pitch. If you have no dispenser and no plan to buy one, a manual-dilution concentrate such as EP67 or Simple Green Industrial Cleaner and Degreaser Concentrated 24 is the better fit for a bucket-and-mop setup. Simple Green’s 13012 formula lists a pH range of 8.5–9.2 and works in floor scrubbers, dip tanks, carpet extractors, and foamers.

Mixing A Batch Without Wrecking The Surface

Mixing order, contact time, and rinsing decide whether a correctly measured batch still damages what you put it on.

For hard surfaces, EP67’s instructions are to apply the diluted solution to a microfiber cloth, use light agitation, then rinse with a damp microfiber cloth once the soil loosens. Floors take a mop or automatic scrubber, get agitated, and air-dry without a rinse. 3M’s procedure adds a warning about overspray landing on floor-finish surfaces.

• Pre-test painted, rubber, vinyl, porous, polished, and coated surfaces in a spot nobody looks at.
• Skip the stronger mix. EP67’s documentation warns that improper use or dilution can affect performance and raise health risks, and stronger batches leave more residue.
• Rinse when the label asks for it. “No rinse” applies where the product directions permit, not to every surface.
• Dispose of wastewater under local requirements rather than down a storm drain.

The full sequence, in order:

1. Read the label and the SDS for the exact product before opening the container.
2. Pick the ratio for the soil level and confirm the surface is compatible.
3. Measure both parts; water into the container first where specified, cold water where required.
4. Label the bottle, pre-test a hidden spot, then apply and let the solution dwell.
5. Agitate, rinse where the directions call for it, air-dry, and dispose of the wastewater properly.
