[Shop-talk] Chemical rust remover?

[cornerexit]

I'm refurbing an older woodstove that has some rust on the outer skin. I've
used a knotted wire brush on a 4" grinder to get most of it off but there is
still some present in the small craters. I was wondering if there is any
sort of chemical rust remover that would clean the rest of it up before I
paint it? Preferably something that can be purchased at a retail store vs.
online.

 

Thanks
