Nuts and Bolts in Rusteco Liquid

This was the first time I used the Liquid and while the Rusteco gave me no trouble what-so-ever, the powder coating was a different story. First I used a hardware store stripper to try to remove the powder coating. It took a long time and quite a bit of scrubbing in rubber gloves, goggles, and respirator before I thought I had gotten it all off. I dropped the bolts in a covered container along with the Rusteco, and actually left them in my bedroom with me over night. I didn't notice any odor at all. I decided to leave them in for 72 hours (which is the longest recommended time period) to see what that length of time would do to the bolts as well as to make darned sure they were completely de-rusted the first time around. When I took the bolts down to a local car wash to use a pressure washer to blast them clean, I discovered that the hardware store stripper had left a bunch of the powder coating on them. The pressure washer had managed to remove what I thought was the remainder of the powder coating so I went home and dropped it in a new cup of the Rusteco (the old Liquid had turned black and as I found out with some trial and error, its de-rusting capabilities were all used up). I just let them sit overnight this time around and the remaining rust that was uncovered by the pressure washing was removed...all except that which was still covered by more powder coating residue. This time I had gotten in a sample of EFS-2500, an environmentally friendly stripper that is distributed in the US by TMT Services Corp. and I dunked the bolts in that and let them sit for 24 hours. The new stripper removed the remainder of the powder coating, and I again, dunked the bolts into a fresh container of Rusteco. Photo: Ryan King, 2006.
