Has anyone used Eastwoods Rust Dissolver? I removed all the guts from my front doors and got rust. (duh) The rust is not through the metal but its in places that are not that accessible with a wire brush. According to the ad, it dissolves the rust and then you can paint over it. I would probably use Eastwoods Encapsulate paint to finish the job.

No but I have used the phosphoric acid at Home Depot. It cost about 20 bucks for a gallon and you can cut if 50/50 with water. Here is the results of my frame after a couple of sessions of the 50/50 mix. For the frame I sprayed it and wrapped it in plastic so the the stuff would stay wet longer. Its active as long as its wet.

Here is what it looks like its under 20 bucks.

Nick, what do you mean? Phosphoric acid is the active ingredient in most metal prep solutions.

I have been looking for a source for it, so thanks. I use muriatic (hydrochloric) acid to remove rust on some things, but it also attacks the metal so you have to be careful. I tried to find "Milkstone Rinse" (contains phosphoric acid) when I was in Texas but couldn't find any. Guys tell me it removes rust very nicely without attacking clean metal.

I'm talkin about that worthless Eastwood product - true phosphoric works like a champ!

Note that there's a difference between the metal prep solutions and phosphoric acid.

My experience with phosphoric acid is that the clean metal flash rusts very quickly. Maybe is was just the weather the time or two I tried to used it. The metal prep solutions leave a zinc phosphate coating that allows the surface to avoid surface rust for a fairly long time.

No Rick I don't think its just your experience its been mine also. The prep and etch I use says you can paint over the coating but I never trusted it. So I rinse it off and yes it does flash rust quickly, so I wipe it dry and wire wheel and sand the flash rust and coat with epoxy primer.

I have the Eastwood stuff and bought their paint encapsulate. I am using a Dremel on the rust areas to peal off the loose rust and then going to use that rust dissolver then paint it with the encapsulate and finally with base coat. I don't have large areas to use the dissolver like you other guys. I have rust around the inner window frames. I am trying not to buy a door. I have not started yet as I am just finishing up with front door and rear floor courtesy lights.

=====================================

Well, you guys were right. That stuff sucks.

The prep&etch that bam55 posted is one of the best things ive found for the price. works great when is worm. i neutralize it with baking soda water though, and rinse with hot water.
one thing i found was if you get a large kid pool inflatable type 3 gallons of prep in a 12 x6 pool you can do some big stuff, i dipped my doors in a day and they are still clean as a whistle inside, a year later. just keep the kids and dogs out.

You can get Milkstone from Tractors supply, we use it around the farm all the time for cleaning irrigation equipment and milking machines. As far as using any of those acid products feela's I have to tell you and I can't stress it enough, Wear your PPE, Personal Protective Equipment. My shop at work uses it every day to clean parts we make and if you get it on your skin yes it will give you a nasty burn but even if you use the medicated creams to relive the burn the exposure can cause heart attacks so please use extreme caution

BK, I went to Tractors Supply in Texas (west of Dallas) and they didn't have any milkstone rinse...they didn't even know what it was and couldn't even tell me who had it. We now have a Tractor's Supply about 30 minutes away in a dairy farm area, so they might have it. I think getting the HD phosphoric acid makes more sense to me.

West of Dallas - most of the "KIDS" (not the sheep, but close) don't have a clue what a tractor is unless the saw it in a movie. They amount to what most parts store attendants are - if it isn't in the computer they have no clue.
