Cleaning Solution Dilution Calculator

About this calculator

Concentrated cleaning chemicals are almost always sold to be diluted before use, with the label giving a ratio like 1:10 or 1:64 meaning one part concentrate to that many parts water. Mixing it wrong in either direction wastes an expensive concentrate or leaves a solution too weak to disinfect or clean effectively, which matters especially in janitorial and food-service settings where dilution ratios are tied to EPA-registered disinfectant label instructions.

This calculator takes your bottle or container size and the stated dilution ratio and splits it into the exact volume of concentrate and the exact volume of water to add, removing the mental math of converting a ratio into real-world measurements for a specific spray bottle, mop bucket, or dispenser size.
