I'm not sure what is in this stuff.. The SDS says that there is nothing harmful as defined by OSHA. I don't know if that is just because the concentration is low enough or what, but it does say it will etch glass, which a lot of acids won't. This lead us to think that it may be hydrofluoric acid, which is some real nasty stuff.The valve covers and intake parts are off of a Subaru engine. I soaked those parts for 15-20min in a 1:4 ratio of Alumanew to water and then pressure washed the black residue off. I also tried to soak the engine block, which is all aluminum except for the iron cylinder walls. I got mixed results on the block. It still required scrubbing. I wouldn't recommend using it on a disassembled engine block or cylinder heads, because this stuff will get into every hole and passage and require using brushes and WD40 to get it out and stop the reaction.Definitely wear protective gear, eye protection, long sleeve gloves and use it outside if you're using it in a stronger ratio than recommended. You'll definitely want to use eye protection while washing the parts off. While soaking your parts you'll notice bubbling/foaming and an increase in temperature of your solution. I noticed some eye and nose irritation when I got too close to it. Stay upwind of it when pulling the parts out or soaking it. Just do it outside away from where you're working or waiting.Whatever you soak will come out with a black residue all over it. Using a pressure washer will take it right off, otherwise you will need to use a brush and/or fingers and fresh water to clean it off.This stuff will also strip the protective plating off of steel parts/nuts, bolts.Would I use it again or recommend it? Depends on how intricate the parts are and how many deep holes/passages there are. I soaked the water inlet housing, which is all aluminum with no steel attached to it and I was surprised at how well it cleaned all of the build up off of it. It's worth giving it a try if you're ok with the dull aluminum finish. Just be careful using it and wear appropriate PPE like I said before.

Clean aluminum like you would not believe really good.Easy to use

I put this on my toons - followed directions - and I have streaks. Don't know how to get them off and they look terrible. It did clean them up and make them look really clean otherwise.

This stuff is really strong, purple power has a 5 gallon that’s cheaper per oz but honestly it doesn’t compare Aluma bright, is a much better product.
