Rusty springs

Ok I bought some coil springs that has some rust on it. Before I put them on I would like to clean them up. I have been trying to sand them down but can’t get in side for a good clean. My question is is there a product out there I can soak them to do a quicker job. I was thinking acid. Thx

They have alot of chemical rust strippers at any auto parts store that will work. I wouldn’t use acid on them.

do you have access to a sand blaster?

I wish. And I don’t want to pay a lot for someone to sandblast. Need to save the money for the other things I need for this lift.

hand hand the scale off with heavy grit paper. prime them with rustoleum and paint them flat black = done. you’ll get new ones for other reasons before the rust does anything too bad.
