Cost-Effective Way of Removing Rust and Grease Stains?

Hi guys, has anyone got any tips for removing rust and grease stains from my gel coat that won't break the bank?

Oxalic acid will do this.

Oxalic Acid Crystals

If the stain is really bad, add wallpaper paste to the diluted crystals, then slop the resulting paste onto the stain, and it will remain in place until you are ready to wash off!

Davis FSR does a good job.

Just don't leave it on the gelcoat too long. My gelcoat is an ivory shade, not pure white. The FSR bleached it out where put some on and got distracted by something else.

The active ingredients of “FSR” are (gelled) Oxalic Acid & Isopropanol (rubbing alcohol).

I use a spray that I bought at Home Depot - "Rust Away" I think. Spray on, let sit, hose off - rust stains gone.

Another excellent product, based upon Oxalic Acid, “Bar Keepers Friend”.

“Rust Away” is based upon mostly Phosphoric Acid, with a little Glycol Ether, Hydrochloric Acid, and Methanol.

There is also a liquid version of Bar Keeper's Friend that I use - it specifically states rust remover. I've not tried it on fiberglass but it works really well on my stainless.

Mmm, wallpaper paste. Yummy. Also known in the US as "wheat glue" it is mainly just wheat flour, which probably would be cheaper and faster to grab. (And that's also why roaches can survive on just wallpaper paste, they're eating dried wheat gruel.)

I used Vanish toilet bowl cleaner -- at least I think that's what it was called; it started with a V, for sure. It worked great and since I bought it at the supermarket, it was CHEAP.
