bhorlings Posted December 8, 2008 Report Share Posted December 8, 2008 So last night I helped my wife out and spray painted some caps to a baby food jars for a snow globe project she is making for her class. I thought I had everything sealed off but I guess I did not so when I went down to pour some baits I noticed a white film on my molds. I am guessing it was the spray paint I used yesterday because it was not there two days ago. Does any know what I could use to safely clean / remove the paint without damaging my aluminum molds?

rxfish Posted December 8, 2008 Report Share Posted December 8, 2008 I would think a very fine steel wool would work. Quote Link to comment Share on other sites More sharing options...

Delw Posted December 8, 2008 Report Share Posted December 8, 2008 I would think a very fine steel wool would work. ABSOLUTELY NOT Dont ever use anything that will scratch the surface on alum that goes for your wife's scrubing pads in the kitchen sink. Floor degreaser and water works well with a sponge. a heat gun works with a damp sponge degreaser carb clenaer works also. more than likely you can just pour and it will be fine as there are all ready oils on the alum from the last pour or just use a damp sponge if you use any degreaser(waterbase) rince them off with plain water Immediatly then blow dry as ZEP floor cleaner will turn alum brown if its too much. You can use your wifes dishwasher however NO HEAT and Little to no soap. then rinse really well and blow the water off. Delw Quote Link to comment Share on other sites More sharing options...
bhorlings Posted December 8, 2008 Author Report Share Posted December 8, 2008 Thanks for the quick response guys. Here is what I did so far: After doing some reading on the internet I took some WD-40 and spray a mold. Then I let it set for a few minutes and wiped it clean. I could not believe how dirty it had gotten. My towel was completely black! Then I repeated the process again. After reading some replies here I rinsed it down with water and wash cloth. Then I blew it dry with a heat gun on a low setting. This mold now looks brand new. I cannot believe it. Is there anything else I should do? I do have a question on cleaning the cavities too. Can I use a toothbrush to clean it out really good or is that too abrasive? Quote Link to comment Share on other sites More sharing options...
Delw Posted December 8, 2008 Report Share Posted December 8, 2008 tooth brush works fine, I forgot all about the wd-40 and i use it all the time. its one of the best cleaners for alum, also not a bad lubricant when cutting alum, i have a can setting by mh hand mill and hand lathe all the time just for that.

rr316 Posted December 8, 2008 Report Share Posted December 8, 2008 We always use windex as a lubricant when cutting or drilling, I don't know why but it works Quote Link to comment Share on other sites More sharing options...
