As others have mentioned, this product arrived very poorly packaged…It was loosely packaged in a box, with a bit of packing “crate paper”….This is a great product, but definitely a “dangerous good”…The Amazon delivery person, had no idea that he was delivering a bottle of concentrated Phosphoric Acid and there was no label to that effect on the outside of the package…As I said earlier, the product itself is excellent, and I would highly recommend using it for the removal of rust…I would give a 5* for the quality of the product, and a 1* for the packaging…

OSPHO works great and is made in USA. I have been using it on tools, drill bits, lawnmowers, etc., for years and recently bought a gallon to eliminate the severe rust under my car (c'mon Toyota!). To clarify, this isn't a rust encapsulating paint, it's a rust eating/neutralizing acid type treatment. It eliminates rust (turns black) so it can be repainted.There are a few reviews that said it didn't work completely - it actually works great, but with a few caveats:- On deep or thick (layered) rust you should wire brush it first to expose the bottom layer. If you don't, there may still be rust under the top layers. Close pressure washing works also.- Any oil or coating on the surface can prevent this from getting to the rust. When necessary, I use alcohol or dawn detergent to clean the surface. With any detergent you must rinse thoroughly, as some leave a water spot reducing film.- On heavy rust it's good to wire brush after treatment to make certain you got it all. A few times after treatments I wire brushed and rust dust appeared. A second treatment usually gets the rest in heavy rust applications.It was great to find this in gallons at a very competitive price!

I've tried quite a few rust converters with mixed results. Most that work seem to always have a downside or need to be cleaned up afterwards. This stuff works awesome and is about as simple as it gets to use. Just spray it on and let it do its thing. No need to clean the next day with acetone to neutralize the product. It will leave a whitish film after a few days that can simply be brushed away before painting. I've used this on my Sprinter, our excavators, our semi's, dump trucks, heavy equipment, etc. The rust goes away and unlike some of the other stuff I've tried it doesn't start growing again a month later. Highly recommended.Oh, it's more cost effective to get a gallon than the quart size. Make sure you compare prices before buying.

I’ve used Ospho for 30+ years in the marine industry and always keep some around the house. It can be sprayed on, brushed on or as a dip for tools and other Iron, Steel or Aluminum items that need stains or rust or aluminum oxides removed. Works instantly on faucets, shower heads and tubs to remove calcium deposits and rust stains. Works great for iron stains from well water. Household rust removers don’t hold a candle to this stuff. It’s real strong so you’ll need to rinse off what you’ve used it on. Try not to get any on ya…

I sprayed my rusty diamond plate bed twice in 4 days with no sand paper or muscles required to get it ready for paint. Just a broom and some air get the loose dirt out before paint.I then connected this 32oz. quart can of White Rust-Oleum 7797502 Stops Rust paint to my brand new Mixing Mate 10-091 Quart Size paint mixer and mixed up the paint. Incredibly cool! I then poured this paint into this mason jar that screws on to the Critter Spray Gun. I then hooked it up to my DEWALT DWFP55130 Heavy Duty 200 PSI Quiet Trim Compressor with my inline TEKTON 4755 Oil/Water Separator filter I installed on the end of my spray gun.I then painted the back of my once rusted one ton utility bed and sides of my truck, which is no longer rusty, because I sprayed Skyco Ospho Surface Prep on it with a cheap old spray bottle. The Rust-Oleum 7797502 Stops Rust paint is of good quality. The mixing with the Mixing Mate was incredibly easy. What an invention!The compressor handled the job easily, not to mention it's the quietest compressor I've ever used! I'm so impressed with this Skyco Ospho Surface prep for removing metal rust. I didn't have any sanding or prep either! The Tekton filter had a tablespoon of water inside of it after I was done painting. All I did was push the button and out came the water. The Critter Spray Gun, Rust-Oleum Stop Rust Paint, Mixing Mate for paint, DEWALT DWFP55130 Quiet air compressor, Skyco Ospho Surface Prep, and the TEKTON 4755 filter all performed with quality. All 6 get a five stars rating! That's a 30 star review!
