You can get it from any pool supply store

I'm thinking someone is boosting from their HS Chemistry closet.

So 5% HCl, 95% water?

I've got a lot of parts to clean ;)

we used to use about 8-12% solution to scrub all the shit off aluminum hulled boats

Try a 5% solution next time.

My friend and I have an almost unlimited supply of this stuff. We added 50% water to a chemical bucket, then 50% of that stuff, followed by another bucket with nothing but soap to stop the reaction. We tried cleaning my motor arms since they were gunked to shit, but it ended up pitting the metal. Then we took an old rusty tool and dipped it in, and it got rid of all the rust and looked awesome, but it also wore away the zinc coating and now it's even more rusted to shit.
Any way of actually producing good results with this stuff?
