How to calculate the dilution ratio or PIR% for Bilt Hamber Auto Foam. This video shows how to measure the output of a snow foam cannon so that you can work out how much auto foam liquid to use in your snow foam lance to get the correct mix ratio. The PIR% or panel impact ratio percentage is the % of the snow foam which is actually detergent. Bilt Hamber recommend using a PIR of 1 to 5% depending on how dirty your vehicle is.
