Dilution – Action’s Guide to Mixing the Right Solutions

Getting the dilution right starts before anyone fills a bottle or bucket. Your team needs to know which product to use, what its label requires, and whether the instructions refer to the amount of water or the total finished solution.

That last distinction matters. Adding concentrate to a gallon of water is different from making one gallon of ready-to-use solution. Here’s how to read dilution instructions, check the math, and make the process easier to repeat across your facility.

Start with the product label

Check that the product is intended for the surface and task. A concentrate may have different directions for different applications; a ready-to-use product generally needs no dilution. Follow the manufacturer’s instructions rather than applying one mixing ratio to every cleaner.

Before dispensing, identify the required concentration, measuring units, water temperature, and mixing order. Review the safety data sheet and your facility’s procedures for protective equipment, handling, and ventilation. If the directions are unclear, ask your supplier before mixing.

Understand what the ratio means

When a label defines a ratio as one part product to four parts water, 1:4 means five total parts. “Parts” can be any consistent unit of volume. Use the same unit for both ingredients.

Do not assume every manufacturer uses ratio notation the same way. Written directions such as fluid ounces per gallon take priority over a generic chart. This dilution-ratio training video offers another explanation of parts; your specific product label remains the instruction to follow.

A gallon of water is different from a gallon of finished solution

A U.S. gallon contains 128 fluid ounces; a U.S. quart contains 32. For a ratio explicitly defined as product to water, count all the parts when calculating a target amount of finished solution.

These examples explain the arithmetic only. They are not recommended mixing rates for any cleaning product.

In the first example, divide the water amount by four: 128 ÷ 4 = 32 fluid ounces of product. The result exceeds a gallon. In the second, divide the desired total by five: 128 ÷ 5 = 25.6 fluid ounces per part. Four parts of water equal 102.4 fluid ounces.

Make sure the container can hold the intended batch. Do not fill a bottle to capacity with water and then add concentrate. Use the product’s specified measuring method and mixing order.

Make correct dilution repeatable

• Measure consistently. Use compatible, clearly marked measuring equipment or a manufacturer-approved dispensing system. Avoid estimating by eye or using an unmarked cap.
• Check dispensing equipment. Confirm the correct product is connected and the setting matches the intended application. Follow the manufacturer’s inspection and maintenance instructions.
• Identify the solution. Follow your facility’s container-labeling procedures so workers know the contents and hazards. Never use food or beverage containers for cleaning chemicals.
• Train before use. Show employees the actual label, equipment, and measuring procedure they will use. Never mix different cleaning products.

Disinfectants need more than the right ratio

For an EPA-registered disinfectant, follow the label for dilution, approved surfaces, and application. Keep the surface visibly wet for the full labeled contact time. Follow any required precleaning or rinsing steps. Correct measuring does not replace the rest of the directions.

Do not solve every cleaning problem with more concentrate

If a floor looks streaky or a surface still looks dirty, check the product choice, dilution, tools, and cleaning procedure before changing the mixture. Adding extra concentrate can waste product and may leave residue or damage an incompatible surface. A weaker mix may also fail to deliver the intended result.
