Hey guys, ran into my first gutter brightening that purple power wasn't providing great results. I started yesterday with a gallon left over from last year, made a difference but not much. Bought a new gallon this morning and nothing. Putting it on full strength with a brush ,letting it dwell a couple minutes and then some elbow grease. ...... nothing. I usually get exceptional results ,not sure what's happening here. I even went from shade to sunny side of house and still nada. Gutters are old but not terrible, plenty of paint left. Morning temp is about 49°. Any thoughts or a different product that might get it done? Thanks Erik

It's usually best to do gutter brightening above 60 degrees. Try totally awsome too.

It was likely the temperature,..49 is really way too cold,..even with Sunshine. If you've done it before,..you got lucky.

I like F13 from PT

Temp does make a difference but one gutter product I use from local stores that I believe is butyl based does seem to be best when fresh, stuff from previous season doesn't seem to work nearly as well. (Chomp pro gutter cleaner)

Thanks guy. gonna try it again this week when its over 60

Yep Super Clean. Spray it on and wash it of right away. I mean right away! You let it even think of drying and you are screwed. But if that doesn't clean it nothing will.

I don't do much gutter whitening these day
