shadeline Posted September 18, 2016 Report Share Posted September 18, 2016 I just bought some old do-it molds off ebay. They still pour ok, but they are nasty looking. They have oxidation and rust. Does anyone have any ideas on how to get these clean? Is there something that would make them shine like new again? Quote Link to comment Share on other sites More sharing options...
Jig Man Posted September 18, 2016 Report Share Posted September 18, 2016 CLR might help with the rust. Acetone is my go to cleaner for anything that won't melt. Quote Link to comment Share on other sites More sharing options...

Does anyone have any ideas on how to get these clean? Is there something that would make them shine like new again? I'm curious are these made of Ferrous metal? I was under the impression that they were aluminum? Oxidation is much different than rust. Quote Link to comment Share on other sites More sharing options...
Apdriver Posted September 18, 2016 Report Share Posted September 18, 2016 I'm thinking a good industrial cleaner like simple green and a pressure washer will take care of things. Might have to go at it more than once if it's real stubborn. I would try this first before I used more aggressive methods. After cleaning, be sure and dry and oil the hinge. The roll pins usually are ferrous. Quote Link to comment Share on other sites More sharing options...
walleyeking Posted September 19, 2016 Report Share Posted September 19, 2016 I've got a couple I got from a guy who stored them in a bucket of lead. They have alot of the white oxidization on them. I hAve tried a bunch of stuff guys on the Do-it forum suggested including clr vinegar and borax. None of them have done much good. I think I might try your idea AP next and pressure wash them.

Apdriver Posted September 19, 2016 Report Share Posted September 19, 2016 I've bought a bunch from a guy and some of them look like three miles of dirt road. Next time I use my pressure washer I may try it myself. I have three Nozzles and the get pretty aggressive quick. Not aggressive enough to move metal but will work the paint on those handles over, for sure. I think I'll take my handles off before I try it. Those handles slide off after you take the screw out and I've had to bump them with a hammer and wood block. Quote Link to comment Share on other sites More sharing options...
walleyeking Posted September 19, 2016 Report Share Posted September 19, 2016 AP if you get to it 1st let us now how it goes. I'll do the same. I've got the handles off already. I beleive your right, the pressure washer would probably do a number on those handles. Quote Link to comment Share on other sites More sharing options...
Apdriver Posted September 19, 2016 Report Share Posted September 19, 2016 Will do. Quote Link to comment Share on other sites More sharing options...
Basseducer Posted September 19, 2016 Report Share Posted September 19, 2016 I have used my hobby blaster with a 220 grit media to clean some molds in the past. Quote Link to comment Share on other sites More sharing options...
andy1976 Posted September 19, 2016 Report Share Posted September 19, 2016 If they're functioning well i would just spray the cavities with drop out release. I thought about pressure washing a few of mine. They have powder coat so I may try getting them hot to soften the powder paint.v Quote Link to comment Share on other sites More sharing options...
