I just now saw a notice from POR15 about their rust remover. A product I haven't seen before. It's different from the POR15 products I'm used to seeing. Has anybody tried it yet? Is it good? Any suggestions or reports? Thanks https://porproducts.com/por-15/rust-remover WHY BE ORDINARY ?
Haven't seen it or tried it, but by bumping this to the top maybe somone will see it who has tried it, and I'll also be subscribed all at the same time
Why would someone who makes a product called "Paint Over Rust" decide to market a rust remover. I just "Googled" it and "51504bat" is correct; it is pricey. I guess it IS "all about the money"!
Just read this on their site: 'All of the rusted areas must be submerged in the Rust Remover for it to work. When all of the rust has been removed, rinse the metal pieces with water. POR-15®Rust Remover works in as little as 20 minutes for light rust or overnight for heavy rusted metal.' So, it basically works the same as white vinegar, only it's $27.50 a gallon vs $2.00 a gallon. Not a bad gig if you can get the work...
"Slowmotion", I don't think that is correct. I agree with "51064bat" that it is probably a "Chellation Agent" like "Evaporust", which means it is definitely not an acid. A few months ago I spent some time with a package of "pH strips" and a bunch of rust removal agents. Stuff like "Evaporust", "Rust-911", and "Metal Restore" (from Home Depot) all tested out with a pH of 7. Try that with vinegar, or any other acid for that matter; they will probably be less than 2. Any acid is capable of destroying metal if used improperly.
Yep, pretty much like feed grade mol***es at about $3 per gallon. Removed 90 years of rust off an entire car body. https://www.jalopyjournal.com/forum/threads/rust-removal-the-miracle-of-mol***es.557996/
we used CLR and a red scuffpad on some lightly rutted sheetmetal and worked great I submerge bolts and smaller parts in it regularly, does a good job and X2 on mol***es
Could be tubman, I had to look it up: "Chelating agents are chemical compounds that react with metal ions to form a stable, water-soluble complex. They are also known as chelants, chelators, or sequestering agents. Chelating agents have a ring-like center which forms at least two bonds with the metal ion allowing it to be excreted." Sounds like pretty good stuff, might have to give it a try sometime (Evaporust). So they're two different ways to get the same basic end result. All I know is white vinegar is cheap & works, and I've never had ill affects using it numerous times. But you're right, they're not the same.
I have been looking for "cheap" Evaporust for the last couple of years, and though I've found some information, I have not come up with anything definite. The stuff must really be that expensive, or these people are really good at keeping a secret. I have found it to be the best and safest rust removing product there is. Also, I have found that genuine "Evaporust" seems to work noticably better than the other brands. I have no reason why. There was a thread on here a year or two ago that seemed to suggest that the "Evaporust" type products were based on citric acid. That is not true either; it has a pH of 2, just like the rest. I tend to be a little forgetful at times, so any acidic rust remover usually turns out to be a disaster for me.
FWIW, I've used vinegar for up to 24hrs soak time, no problem. Did some T & A wrenches, came out lookin' like the day Henry put 'em in the trunk! (& they were real crusty) But depending what your working on, it'd be a good idea to keep a vigil on it. Forget it for a week & it might be a problem.
