Dilution calculator
Pick your container and your ratio, and read off how much concentrate to pour.
A foam cannon does not spray its bottle. It draws from the bottle into the pressure washer's flow, so a 1 L bottle can put 11 L on the car and the ratio in the bottle tells you nothing about what reaches the paint. Measure your setup once and the number holds for every product that quotes a PIR.
Nothing matches that. Check the product's own page for its ratio.
Common questions
-
Parts water to one part product. A 10:1 mix is ten parts water and one part product, so a 1 L bottle takes 91 ml of product and 909 ml of water. A few brands print theirs the other way round, so check the label if a number looks unusually strong.
-
Water first, then the concentrate. Pouring concentrate into an empty bottle and topping it up makes it foam over the top, and you lose some of what you just measured.
-
Most diluted products keep for a few weeks in a sealed, labelled bottle out of sunlight. Write the product and the ratio on the bottle. An unlabelled trigger bottle is how the wrong chemical ends up on someone's interior.
-
Panel Impact Ratio is the concentrate as a percentage of everything leaving a foam cannon, the bottle water and the pressure washer water together. It matters for snow foam and pre-wash only, because a cannon draws from its bottle into the washer's flow rather than spraying the bottle.
-
A syringe or a measuring jug with millilitre graduations. Capfuls vary by bottle and by how full you fill them, and at 256:1 a few millilitres out is a noticeable change in strength.
