Rust Stains

Can anyone suggest a way to remove rust stains from gelcoat?

I inherited some stains and caused some myself!

I have tried bleach and cillit bang to no avail.

Thanks

Tony.

Unfortunately it is on the 'knobbly' stuff on the floor.

Is the knobbly stuff flocoat?

Will your solution still be OK?

Thanks.

Rust Dissolver

Hi you could have a go with this;

I would be really interested to see if it does work. I sell a US quart on my site
for 11.99 but if it dosn't work happy for you to send it back and I will provide a full refund.

Rust Dissolver

A safe, acid free rust remover. Removes rust, not metal. Leaves metal ready to paint, plate or powder coat. So gentle, it's suitable for engine parts. Parts can remain in contact with Rust Dissolver without damage. Harmless to copper, brass, aluminum, solder, lead, plastic, rubber, seals, wood or vinyl. Will not remove paint and chrome that adheres to the surface. Removes blueing and other oxide coatings. Rust Dissolver works as long as the surface is wet.

As has been posted before, a great cheap way (it's cheap and it works very well on smooth gelcoat) is solvol autosol; you can get it from any good car or bike shop. It might need a bit more effort on a non slip floor though

just buy some GRP rust remover. About 5 from any boat shop. It's a blue gel, you put it on and the stain just dissapears in about 1 min the rinse off - sounds like some cheesey shopping channel thing but it actually does work like majic!

Gelcoat cleaners like Gelklean or Y-10 will do the trick. It may need a few applications depending on the staining and just rinse off. They will also do a great job of getting a yellowish hull white again. Should be able to get them in any decent chandlery.

Thanks to all.

I think I need to buy some elbow grease as well, then.
