I'm hearing soda for paint but cannot verify it will remove rust?  Would
walnut be better?


Thanks in advance.

Where is the rust?

I have both sand and soda blasting equipment and often use a wire cup brush on a grinder. Depends on access. Soda is for paint removal, especially on fiberglass. Soda is great for bringing dull aluminum back to a fresh cast look.

I also like phosphoric acid to simply dissolve the rust.

Sand is messy and reserved for an aggressive attack on a place that's hard to get at.

Have no idea where I'd use walnut shells.

My first choice is always a wire brush on a grinder; least messy, quick, and thorough.
