  • Woud a highly diluted mix of sulfuric acid and water be okay to clean a saw top?

    I have some 30/1 mix sulfuric acid that I used on ajob a long time ago, would that be okay to use to clean the top of my saw?


    Just throwing it out there, im doing alright with the cup grinder but I saw it and though why not.

      Sulphuric acid -- no. Muriatic, maybe.

      Muriatic (hydrochloric) acid will dissolve rust very effectively, and should not attack the base metal if you use it carefully. However, you will need to rinse it thoroughly and quickly because in the presence of air it will quickly rust again. You'll want to be very careful not to get any of the acid into crevices or mechanism. And, be sure to have ample ventilation, because the fumes will not only get to you, but can cause rust.

      You might also consider phosphoric acid (one commonly available brand name is "Ospho"), which will convert the rust to iron phosphate. On second thought, this might not be too desirable on your saw table, as it might leave black stains which might be tougher to remove than the rust.

      The main problem with the cup brush (other than overheating your drill) is that it tends to polish the rust rather than removing it.

      If the rust is very heavy (to make it worth the effort), and if you can get the table off, and if you have a container in which you can immerse it, you might try electrolytic rust removal (remember, Google is your friend). This might even work without immersion by using pads saturated with the electrolytic solution -- I don't know if anyone has tried this.

      Anything you do should be tried in an inconspicuous place first . . .

        Your cup wheel would be great to knock scale off, but is not ideal for removing surface rust (it is not abrasive). WD 40 and Scotch Brite pads will take it off very quickly.

              Hey TJC


              I couldnt get the grinder properly to the wings so I took them off and filled a 15 gallon bucket I have with the water and baking soda with my battery charger and its bubbling away!

              Ill give you an update on how it goes!

                Man! Nothing like jumping in with both feet . . .

                Just check it frequently and stop if you don't like what it's doing. The recipes I've seen call for washing soda (sodium carbonate), not baking soda (sodium bicarbonate).

                    Use a 50/50 mix of motor oil and diesel fuel. Pour the mix over the table and rub in with steel wool. The fuel, together with the wool, will cut the rust, while the oil will lubricate and help to retard future rusting. Note I did not say eliminate - retard.

                        Most recipes do call for washing soda, but I have used baking soda, and it works just fine.
