Can that be restored or cleaned and how could it be prevented when floor is getting degreased and cleaned twice a month? Thanks!

Wow... I thought that I was the only person to have that problem.

I tried buffing it, I had a company come out and apply hydrofluoric onto it, and never had any real great results.

All in all the buffing seemed to work the best, but in no way was it persect.

I know have a roller on all of our trailers, they apply a vinegar coat onto the aluminum first.

I mix the vinegar with a gelling compound, kinda goes on like the alcohol hand sanitizer, you know those little bottles with some gl type mix in it. It has a very limited life on the surface but long enough for us to apply sodium and potassium hydroxide, wash the Crete and rinse.

If you can get it off, keep me informed. I know that the 3M corp would love to develop a product of this type.
 
it looks like you may have taken off the anodizing. Did you use somthing with sodium hydroxide in it?

So basically you apply a light acid as a barrier on the aluminum surface mixed with something for better cling so it neutralizes the base when they get in contact. When you spray down the sodium hydroxide based degreaser or while rinsing, you have enough time to get to clean the concrete and protect the aluminum from it... I get your idea, but I think its already late in my case :(..

I'll let you know and will post some pics if I find a solution on that issue.
 
3M makes a spray barrier in an aresol. Its used for car painting its like a clear waxlike coating that can be srpayed on to something so overspray wont paint the surface. then you PW it off. Might work Ithink its called spray mask. are you guys just spraying the heck out of the crete or are you hitting the door directly when applying chems?

The place is getting cleaned every 2 weeks. When we started it was really messed up, so we pre-treated the surface the first 3-4 times with real strong mix of butyl degreaser. All the foam and splash generated from the surface cleaner got in contact with the bottom part of these anodized aluminum doors. I never noticed that the chemical has eaten up the anodized coat until it was already late. If I new before, I would either spray it with some protection or even tape it with painters tape.

From my short research, it seems that the only solution is to have the de-anodized/oxidized aluminum surface buffed and polished as good as possible and then spray it with clear lacquer.

I have never read or heard similar issue on the boards or another contractor, but I strongly recommend an extra precation to those who do store fronts, shopping centers and restaurants. Anodized aluminum door and window frames are very common. We just started our complete maintenance service on two brand new shopping center where all the door/window frames are anodized aluminum. This could be quite a mess if we repeat our mistake.
 
Yes... get yourself the vinagar mix, and you got it 100% the was you described.
 
I have a cusotm made mix, that I developed, however the are a few sites on the net that help you get the gelling compound.

Try usung cocamidopropyl -- cyclomethicone -- 1 part by wait ferric sulfate -- disodium citrate, try you alchamist best, and you will come up witha great mix that make the glacial aciatic kling well.

DO NOT USE ON UNPAINTED WOOD
