Cleaning dilution calculator

Direct answer: water to add = concentrate amount × the second number of the dilution ratio, and total solution = concentrate + water. For a 1:10 ratio, 500 ml of concentrate needs 5,000 ml of water, giving 5,500 ml of solution. This page does the arithmetic for you — nothing is sent anywhere, and no signup is needed.
