Need help removing BAD rust!
I am trying to remove real bad rust on an old 1920's hand wrench, a very old stove top kettle, and lock. I've tried CLR [affil link], sandpaper. And nothing works please help!Mary Mcgill

Try and scrape off as much of the rust off as you can. CLR [affil link] and sandpaper should work, but maybe there is a lot of caked-up rust. You could also try Muriatic Acid [affil link], but CLR or Sandpaper [affil link] really should work if the rust is not too thick.

Note:CLR [affil link][Cal / Rust / Lime Remover] is a rust remover (there are other brands out there) which have complexing agents which also dissolve hard water deposits, and remove some stains.

I have cleaned an old stove top kettle by bead blasting (or sand blasting). Perhaps you could find a shop near you that does this. Most of the rust removers I know of will not get all the rust out of the rough surface. You might try "Naval Jelly [affil link]". Just make sure after you get the rust off to coat the metal with rust preventive oil or other finish to stop the return of more rust, which will not take too long as you will have very bare metal.
Good luck,Ed Kay
