Two-Concentrate Blend Calculator

Split a finished batch between two concentrates, such as a cleaner and a sanitizer, in the right proportions.

Inputs

Range: 0.01–1,000

The dilution of product A in the system. A system that calls for 1 oz of A per 64 oz of water is 1:64 here. This is a dilution in water, not a share of the finished batch.

Range: 0.01–1,000

The dilution of product B in the same water volume. Both concentrates go into the same water, so the water is the basis and the batch is what results.

Range: 0.25–100 gal

The water is the basis of a two-product system: each concentrate is diluted into it at its own ratio.

Range: 0–1,000,000 per gallon

Reading: what this result means for the job
A strong product A in the blend. A ratio this low means the water is a small part of the batch, so check the system really calls for it and that the two products are designed to be used together.
Applicability limit
The blend follows the two ratios and the water volume entered, and each ratio is a dilution of that concentrate in water rather than a share of the finished batch. Two concentrates mixed to the wrong basis produce a batch that is strong on one product and weak on the other. This is a planning figure for the values entered, not a measured result. Coverage rates, product yields and application rates are properties of a specific product, applicator and substrate, and the label or data sheet for the product you are using always takes precedence over the default here. The EPA-registered label governs. Using a registered antimicrobial inconsistently with its labeling is unlawful under 7 U.S.C. 136j(a)(2)(G), and 40 CFR 156.10(i)(2)(ii) requires every label to carry that statement. This tool does arithmetic; it does not approve a dilution, and it does not determine compliance.
Check before the job
Warning: a dilution of less than 1:4 on product A is close to neat. Confirm the two products are designed to be blended at this strength before mixing a batch.

What to check

  • Confirm the two ratios come from a system that was designed to be blended.
  • Check the order of addition, since some systems require the sanitizer last.
  • Verify the finished batch with the manufacturer-specified test kit or other device.
  • Enter the water volume the system instructions state, not the finished batch volume.

Two-product systems have a fixed relationship between the two concentrates: the cleaner ratio and the sanitizer ratio are set by the manufacturer together, and both are dilutions into the same water. Mixing them independently from two labels usually produces a batch that is either too weak on one or too strong on the other. This tool asks for the water volume and the two dilutions, and reports the finished batch volume and the strength of each product inside it.
