Post CLEANING FRAME,,,,MURATIC ACID??????

Hi everyone !!!! It's been a while since I've visited here, Hows everyone been??? Just looking for an opinion,,,I'm ready to clean and paint my frame,it is sandblasted and primed but after doing body work in the shop my frame is full of dust. What do you suppose would be the best way to clean it. I have "mineral spirits" or "muratic acid" what do you guys think?

I used a 25/75 muratic acid/water mix to clean my frame. It works great. One thing to make sure of is that you get all the acid off. Wash it with a bunch of water. You have to then dry and paint it very soon after. Surface rust will start very quickly. I had a few places where i did not get all the acid off and it rusted through the paint in a matter of weeks. I had to reclean and paint those areas again. No problem after that. Paint is a year old now with no rust problems.

I was considering using the mineral spirits for the simple fact that it would evaporate and dry on it's own without leaving those ugly yellow stains generally associated with muratic acid, eliminating the use of water all together. I wouldn't think it would rust from mineral spirits would it <img src="confused.gif" border="0">

I would use one of the metal prep acids like Rust-N-M-Me. Will clean, etch, kill rust and leave a phosphorus compound on the surface that aids paint adhesion. Just don't use it over cement - it will consume it in mass quantities! Stuff is cheap.

Your paint supplier carries it or a similar product. Yes, it is intended for sheet metal body work but obviously can be used to advantage on any bare steel painting project.

The great thing about muratic acid is that it cleans paint, rust, grease, dirt, and pretty much anthing that is not steel. Dont try it on aluminum though. Your alumnum will magically vanish.

It works well for all small steel parts.

Does Rust n-m-me have to be wash off after it is used? <img src="confused.gif" border="0">

Nope, leave it on to take advantage of the zinc phosphate coating.
