    I removed the carpet on my aluminum decks and am wanting to put on some Tuff Stuff rubberized coating. After researching, I have seen a lot of recommendations for acid washing the aluminum to etch the surface so that it's ready for primer and then the Tuff Stuff coating.

    Now the simple question, how do I do an acid wash? I don't know what the acid is supposed to be or how to go about doing it.:tounge_out:

    i would try muratic acid it's used on bricks but i think it would work well on aluminum and it also does wonders on old wood floors

    hope this correct and helps

    I've used oven cleaner(heavy duty) in the past to take anodizing off aluminum parts, it left them porus to apply primer.

    Get some air conditioner coil cleaning acid, and follow directions the same as you would for cleaning the ac. It will turn the aluminum a chalky white color when its etched properly.

    Personally, I wouldnt use acid. I wouldnt even use acid in the same room that my aluminum boats in. I would do as Tuff Stuff recommends by cleaning the surface free of paints and oils, rough up the surface with 80 grit paper, and prime with self etching primer. I've done it, it works, and its still on.

    Seth, thousands of people use acid to clean the logs on pontoon boats every year. There is even a product made specially for it called Toon Brite, and the only reason I suggested the coil cleaner over it was because its cheaper, but it is the same stuff. Yea if you were to use it on it every day for a year you'd probably damage it, but for a one time application you'll be fine. If your still worried about it, use the stuff specifically for boat, and follow the directions, or have a boat dealer do it so the liability is on them.

    Heres a link to their instructions http://www.toonbrite.com/AluminumCleaner.htm
    and another link to a dealer. http://www.pontoonstuff.com/pontoon-boat/219-toon-brite-aluminum-cleaner-pontoon.asp

    PS, DON"T use Muratic acid, its not the same.

    If you're stuck on the acid, why not just use some vinegar? Its a cheap readily available acid that wont kill yours or the neighbors pets, so you can just wash it onto the ground with no worries. I've used it to clean the rust out of motorcycle gas tanks, it should etch aluminum. I also second the self etching primer though, it will etch and prime, giving your coating a really nice surface to adhere to.

    Will the vinegar work good for getting the old carpet glue off the deck? I just want to get the glue off now and I'll go with some self etching primer.

    I imagine vinegar would remove the carpet glue eventually, but it might take it a while to soften the glue enough to remove it. Try it, it might surprise you/me.
