Re: Amazing Stuff!
Since Evapo-Rust is an aqueous solution there is always the risk of rust reforming afterwards due to the water entrained in porous items like iron casting. I usually shake, sponge, or blow off as much liquid as possible when done, then soak or flood the item with acetone. The acetone will help mobilize the remaining water to evaporate quickly, leaving a bone-dry casting that can straightaway be painted or treated with WD-40 to prevent rusting. This works really well with Zenith carburetors, with all their internal passageways.
