I have a question in regard to a Uniweld CA550 cutting torch I bought on eBay. The seller told me the following after I asked him how the unit came to be so nice and shiny:Question: How was this unit bead blasted (glass, soda, walnut shells, etc)? Also, who did the bead blasting and polishing?Answer: I do all my own cleaning and restorations. After taping off the holes on the unit, I bead-blast with 80 mesh black diamond glass and then polish with a Dremel brass abrasive head. Then follow up with brass polish.Question: What type of brass polish do you use?Answer: I almost always use Brasso and then clean the residue off with brake parts cleaner.So my question to the experts here - Is there any danger to using this torch after I receive it based on the cleaning process? I have looked at the SDS for Brasso and it seems to have several different formulations over the years, some with hydrocarbons and petroleum distillates.I would think that by now any "leftovers" would have long since evaporated away, but I just don't want to take any chances. Would dunking the whole torch in Isopropyl alcohol (90%) and giving it a few days to evaporate be a suitable answer?
