Bests & Worsts Reviews from Amazon

I've seen a lot of polarizing reviews for this stuff and I think your mileage may vary depending on what you are using it for / what you expect. Is this the end all be all to rust removal? Absolutely not, and I don't think it's mean to be. I used this product to remove (excessive) amounts of rust from old arcade screws and other metal parts, and I was very impressed! I will say that you have to be patient though. The product recommends soaking rusted parts for 2-12 hours or some such. Just ignore that, it's more like 8-16 hours depending how how much rust there is. Again, this is probably not ideal for everyone, but you literally just drop your rusty stuff into a vat of this and come back the next day to basically cleaned off parts. I am perfectly ok with that. I will also note that after using this, my screws did not re-rust at all (after rinsing and drying thoroughly) unlike when I used apple cider vinegar, so big win there as well. On top of it all, I think the major draw of this stuff is that it's pretty safe (no I would not drink it and yes I am still limiting how much gets on my skin / will definitely wash with soap and water after touching it, I don't care how safe they say it is). But compared to stuff like CLR and naval jelly, this stuff is very tame, and if you get some in your eyes it won't kill you, or do much of anything really. Also, disposal is super easy, just throw it down the drain, done. Love it. If you need something that acts really fast, this is probably not the product for you. If you need something that will work on rust that cannot easily be soaked for long periods of time, this is probably not for you. Otherwise, I really recommend it, and I can say that I tried it and it definitely works. Be patient and follow the directions! (I would venture to say the majority of user issues are from not following the directions).
