Soft Washing (SH) Bleach Calculator!

Sodium Hypochlorite Dilution Calculator










Here is a quick and easy bleach calculator.

Say you have the ol’ 26 gallon tank from Northern Tool.

And you have 10% SH that you bought from Walmart or something.

And for this example we are softwashing a roof with a gentle mix of around 2%.

Simply input desired strength at 2%.

Current % is 10%.

Tank Size is 26 gallons.

y voila! We need about:

5.2 gallons of bleach

20.8 gallons of water

And we are good to start washing!
