  • Evapo-rust



    When I use this it usually works great, but it leaves a yellow-beige layer of scum that’s really hard to take off. Is there something I could use to remove it easier?

    Never used it, so I’m no help to you. Have you tried something like vinegar to take the scum off?

      Yesterday I tried vinegar, lacquer thinner, acetone, carb cleaner, Simple Green full strength, nothing touches it, except mechanical removal with a wire wheel. Even a couple hours in my tumbler had no effect. They should paint cars with this stuff.

      Next up I’ll try long term soaking in Pine-Sol but I doubt that will do it. Looks like I’m in for long sessions with a wire wheel. The problem is that it is inside some of the components.

      I’m trying to ask Evapo-rust but so far they didn’t answer Facebook and Twitter messages.

            Crap, can't hardly see that.

            The section of interest: "Note that EvapoRust leaves a gummy yellow residue behind, so don't dunk mechanisms unless you can follow-up by submerging in a gentle solvent."

              I tried that today and it does help wipe some off. I’m going to buy some more in the theory that my supply is spent.

              Evapo-rust did reply on Twitter and asked me to send pictures. I’ll update you on what they say after I do that.

                Here’s what they look like. Before I cleaned these parts the residue was thicker than a credit card. An acid to dissolve this residue would be the ideal method.

                  Well, after communicating with them on Twitter and by phone, we’ve come to the opinion that the solvent probably reacted with lead or cadmium in the metal and the only remedy is more soaking and scrubbing. In the future I’ll be sure to remove items more quickly.

                      Some I can, but I can’t get inside the boxed parts. This weekend I plan on buying some different media to try in my parts tumbler.

                        I forgot to update with what I learned from this experience.

                        After a few back and forth emails with Evapo-rust customer service, they said my problem was due to the cadmium coating on the boxes reacting with the solvent. It produces a residue that can be wiped off when still wet, but if it dries it is virtually married to the surface. Resoaking helps loosen it, but in very small increments, so mechanical removal is really the best way to deal with it.

                        After a lot of time with a scotchbite wheel on my Dremel I finally got them immaculate inside and out and after coating them with clear acrylic I can’t believe they look as nice as they do. It’s too bad that they will disappear totally from view once they are installed

                        In the meantime, a friend referred me to a rust removal chemical from Rustoleum that works excellent and extremely fast, some stuff I soaked looks brand new after only 15 minutes of soaking instead of the 24-48 hours the Evapo-rust seems to need.

                            It’s called Rustoleum Rust Dissolver.

                            https://www.rustoleum.com/product-ca...ust-dissolver/

                            It’s available in liquid and jelly. I use the one gallon liquid which I think cost $24, the same as Evapo-rust.

                            The Rustoleum seems exactly like Eastwood’s Oxi-Solve which also works excellently, but the last time I checked with them they wanted $39/gallon plus shipping. I shouldn’t be surprised that the Rustoleum is so good, I’ve had excellent results with everything I’ve tried from them.

                            Last night I took some pictures of how the parts came out, I’m very pleased with them.
