Hello all. I always see people talking about cleaning before welding using acetone, mineral spirits, or alcohol. It may be a stupid question being that everyone uses it, but are there any harmful effects from welding over an area that is cleaned with any of the above mentioned? I see people that TIG weld use it a lot pre welding, can it be used in any application (ie tig, mig, stick)? Is it something that youd have to worry about if lets say its not fully dried like in that phosgene gas article where the welder didnt know there was some brake cleaner that hadnt evaporated yet? Sorry if they are silly questions but I just wanted to make sure. I also searched and I could really find anything on the topic as far as it being dangerous which leads me to believe that its not, but it cant hurt to be careful right? Thanks in advance!
