what chemical do you guys use to clean new aluminum and stainless before tiggin...a freind of mine cleaned a small engine case with brake cleaner and the fumes were horrible...I was told to use acetone...is there any other chems that are ok to use when in a pinch???
Reply:Never use any chlorinated cleaners like brakleen or electical cleaner as the heat and light of the arc break it down into hydrgen sulfide and phosgene (also known as mustard gas). 409 or simple green sprayed on a clean soft napkin works well for getting light grease and oil off. MEK work very well but its not good for you but it will take anything off.
Reply:thanks alot...i have some simple green....chlorinated?..that smells familiar,made me almost sick. ...thanx again for the info and the warning...later
Reply:For most metals, scrub them with a stainless steel wire brush and then wipe down with acetone(first choice) or isporopyl alcohol (second choice if you don't have acetone). Weldingman's right on the money about both chlorinated solvents and MEK. Really bad for your health. With the acetone, wear rubber glove's though, or it will really dry out your skin, and can give you dermatitis.Zap, I'm sure will let you know where and where not, to store your acetone.I r 2 a perfessional
Reply:suuurreee...put the pressure on me... store in cool place keep the lid on tight (i left a quatr open one day and went home..next day dry as a bone.. dont leave it anywhere on the welding bench.. hi freq will set it off.....zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:lol zaps right. never on metal bench!!!!! but it is the best to clean before the weld and a little brushing don t hurt, it's CLEAN clean clean
Reply:I spent several years working at a plant that produced acetone and MEK. I would avoid MEK unless you have a compelling reason to use it. If so, use it in a well ventilated area.My first choice for a cleaner is simple green or equivalent, next would be alcohol, and then acetone. The first two are relatively cheap and less likely to cause problems than acetone or MEK.
