whats the trick to cleaning aluminum trim

[c4org 14]

pressure washing it doesnt work and i use simply cherry and 12.5% .. black spots dont come off unless i hand wash it... is that the only way? and if i get gutter grenade from pressure tek will i still have to hand wash the black streaks off the gutters

what are you trying to do with the aluminum trim, make it brighter, remove the oxidation?

I have never had to handwash gutters using gutter grenade. Are you mixing it strong enough? I just put mine in a pump sprayer for most jobs. For the really nasty ones I brush it on.

I assume you're referring to the usual metal wrap on homes? Eaves, fascia, etc.? I wash (downstream) these every day with 12.5 and S.C. If they are not coming clean, either your 12.5 isn't or you're diluting it too much.

Agree with John and Lonnie. Your mix is too weak.

Hey, Lonnie- would you go ahead and complete your signature? Thanks!
