Hey all I have never used cleansol or gutter granade but heard both can stain concrete and remove paint very easily. Yes I know keep everything wet
For gutters that are in good condition I find two applications not downstreaming using 100% SH (12.5 pool shock) along with agent blue to be fine
But for heavily worn gutters finding out that results kind of meh, still some soiling on gutters. I am wondering if I forgo the downstreaming and use my 12v pump to apply 25% strength of SH would that get more dirt off?!
Folks tell me bleach does not clean and why you need degreaser but on the wooden porch I only used degreaser and it did a lousy job of cleaning gutters so I am thinking bleach does a fantastic job
