Can you use either CLR or Lime Away to remove buildups in the radiator? Which one works best? Anything else i can use to get rid of those buildups without using prestone radiator cleaner.....aint worth ****. Thanks

 

A guy I know mentioned that he has used CLR.

I bet it does a really go job at removing deposites.

Befor using it. I would take an old seal and let it soak in straight CLR for a few days. Just to see if it would damage it at all.
