About

Professional cleaning relies on precision. Over-diluting chemicals leads to ineffective sanitation, while under-diluting wastes money and leaves dangerous residues that can damage surfaces or harm occupants. This calculator eliminates the guesswork for facility managers and janitorial staff.

It computes the exact volume of concentrate required for any container size based on standard industry ratios. Additionally, the integrated Cost-Per-Use feature allows managers to audit their inventory expenses, revealing the true cost of filling a spray bottle or mop bucket from a bulk concentrate jug.

Formulas

Dilution ratios are expressed as 1:X, meaning 1 part chemical to X parts water. The total parts are X + 1.

Chemical Volume:

V_chem = V_totalRatio + 1

Water Volume:

V_water = V_total - V_chem

Frequently Asked Questions

Not exactly. A US gallon is 128 ounces. A ratio of 1:64 means 1 part chemical to 64 parts water. To treat 128 ounces (1 gallon), you need 2 ounces of chemical (since 128 / 64 = 2). 1 ounce per gallon is actually a 1:128 ratio.

Always fill the container with water first, leaving enough room for the concentrate. Adding chemical first and then blasting it with water creates excessive foam, making it impossible to fill the container accurately and potentially inhaling aerosolized chemicals.

Use measuring cups, pump dispensers (often calibrated to 1oz per pump), or tip-and-pour bottles. Relying on the "glug-glug" method is inaccurate and usually results in 20-50% overuse of expensive chemicals.
