5 gallon bucket, low pressure soap attachment on pressure washer…how much of the bleach do you use with the water for a reasonable dilution. (not taking into account the settings on the dilution knob of the pressure washer) as well as the Simple Cherry??? (see question below)
Simple Cherry…acceptable alternatives??
Thanks in advance
(I don’t have a roof pump yet and I’m referring to cleaning a mildly discolored comp or shake roof)
You can not get a strong enough solution by down streaming or upstreaming whatever you are doing. Even if you put straight 12% sh in a 5 gal bucket you will only get approximately 1% solution on the roof. ( you need to do a bucket test to find out exactly) To properly clean a roof you need around 4% sh on the roof.
Wood shake roofs are different from shingles. Do some research before doing shakes.
How bout If he does not turn the pressure washer on but the water is on and downstream injector is in the bucket with 12.5%? I know when I have accidentally left the downspout injector in with the water on… the solution still goes up the hose and out the gun at a high solution rate… Has anyone tried this before? It’s a cheap alternative but has anyone had success using this method for roof washing?
