Hull cleaner

Does anyone know of or use a special product to get marks and stains out of boat fiberglass? It seems like my deck always ends up with grease smudges or blood/rust stains that are about impossible to scrub out. I figured someone in here would have a truck to keep things clean.

For the deck I use star bright deck cleaner. It pulls up all stains.

I use rust aid from home Depot.

Rust Aid as said above. Ace hardware has a gallon for $10. Works great. Just apply it directly to rust stain and let it sit until it’s gone. But watch out if you have bottom paint! It will stain the paint.

For dried blood-bleach works amazing. Same process as above but it won’t harm bottom paint

Thanks, I appreciate the responses. I have been working on starboard engine a lot lately, finely got it right but now I have black hand prints everywhere haha

For a stubborn stain, I’ll put some Barkeeper’s Friend and make a paste to sit on the stain for a while. Hasn’t failed me yet.

My fishing partner sells aluminum brightner at the end of C building at Ladson flea market I26 side. Its is $7 gallon, he told me for years of how well it cleans fiberglass also. I finally tried and it works like magic. poor some on and scrub a little if heavy stains, rinse and pure white again. It also shine aluminum like new.

Be careful what you ask for, you might just get it!
