Can you mix Evaporust with CLR ?

[Kern Dog]

Awhile back I stumbled upon a couple gallons of CLR….

I already had 5 gallons of Evaporust…

Now I’m trying to clean out light rust scale in a gas tank that is otherwise pretty good.
Is this stuff compatible? They warn of fumes….
I already have 5 gallons of Evaporust in the tank. If the CLR is not safe, what about vinegar ?

I wouldn't. I'm not a chemist but if you star mixing stuff like that and you may get a bad chemical reaction and nasty fumes.

That might explain my “condition”.

Online searches are all over the map.
Most warn against mixing CLR with Evaporust based on not only the fumes but that their incompatibility of composition means at best, they could cancel each other out, at worst they could damage the metal.

I wouldn't recommend it.
They approach rust removal differently.

Thank you. I did read that after I posted this. I figured I’d leave this all here in case someone else wondered about it.

You can always read the SDS (safety data sheet) for each product and see what products are in them. You would still need to know something about chemistry to figure it out or live dangerously and google the consequences of mixing those chemicals or FAFO

I’m not a strict safety guy but I sure don’t want to harm my dogs or burn my place down.

Well Evaporust is 83% water (big surprise) and 16% chelating agent....probably some acid but they list it as proprietary. CLR's active ingredient is lactic acid. Thats all I got.

You could try a splash of each in a small container with some rusty nuts and bolts.

You can mix anything you want.......once.
