  • Cleaning aluminum "big thanks" and pics

    Just wanted to say thanks again for all the responses to my "cleaning oil out of aluminum" thread last month. I tested the boiling water and soap in an old pan I got from GoodWill and it worked. When I told my buddy about it, he asked if I could use a bigger pot for the cleaning. When I said yes, he showed me one of those "deep fry turkey" setups. He had gotten it from his dad, but never used it. His dad used it once and didn't like it. Well, I scrubbed it down again just to make sure it was super clean and then got the propane tank filled. I made an air bubbler system from copper tubing to agitate the water. Tonight was the first try. I put in about 90% too much soap and used too much air pressure. Knocking air pressure down to ~4-5PSI worked a charm. I need to make a cover shield for the air inlet of the burner since the soap would boil over and cover it a few times, causing problems to the flame. Less soap would probably help

    Here are a few pics and thanks again for all the responses:

    Use dishwasher soap. It doesn't foam because there is no one to impress. Foaming soap is only a gimmick to make it look like it is working hard.

      More great advise. I only have the compacted powder pellets, but imagine they just break up and disolve in the hot water.

      Thanks again, Derek

        Dishwasher soak is pretty caustic. It does have some good water softeners in it so that helps but with heat it does like to eat aluminum. Not directed at you so much cause you want to just clear the crap off. But if you have any smallish critical parts the alkali in DWS can be aggressive. Im talkin raw aluminum too. The pots and pans may be anodized to help stay off corrosion. JRouche

          You might try either straight sodium carbonate or TSP. Sodium carbonate is pretty cheap at the spa or pool supply, it's used to raise the Ph level. TSP you can get where there are a lot of painting supplies, but be sure that it contains tri-sodium phosphate as there are some products labeled TSP that don't contain any.

          Neither will be quite as aggressive as dishwasher soap. I've used the dishwasher to start rusing a barrel that needed browning, cleans *and* starts the rust nicely.

            Dishwasher is tsp which reacts with aluminum especially well when heated. Low suds laundry detergent for front loaders that is not also tsp would probably work.

              I thought it was mostly sodium carbonate.... anyway, it's way too alkaline
              for boiling aluminum....

                Dishwasher soap ain't what it used to be. TSP is gone from detergent formulations for quite a while. Phosphates in general aren't allowed in houshold soaps and cleansers. Sodium carbonate is what is in most dishwasher soaps and it doesn't attack aluminum in any particular hurry. It wouldn't do to dissolve the home maker's pots and pans, now would it?
