I was going to suggest Awesome but if that didn't work you might have to buff it off.

 

you might have to use some rubbing compound buff them off good luck

 

Super Clean it is real good on most of the stains on my boat. Just be ready to rewax . I also used Star Bright deck cleaner and that worked great.

 

30 second. I get at Home Depot or Lowes. Soft scrub works as well.

But plan to wax if either is used.

 

Give Bounce brand dryer sheets a try. Just dip a sheet into warm/hot water, to wet it. Do a good swipe circle to cover a arm's reach of an area. While it is soaking in, pic a starting point and gently swirl rub your way around in that big circled area.

If it works, it should go pretty quick.

 

Try a large pink pencil eraser. Works for lots of stuff on fiberglas.

 

Great ideas guys, I plan on starting at the top of the list and working my way down! Won't need to wax most of it no matter what i use as 99% of it is all deck area that is non slip and I don't use wax on it so it stays that way.

I appreciate the ideas, keep em coming, I am going to copy ALL of them down!

 

FRP fiberglass cleaner..GUARANTEED.

 

We had the same problem. We had to park our boat under a plum tree. What we found works well is the powder form of Barkeeper Friend. You can even mix some into a paste and let it soak for the real stubborn stains. Just make sure you rinse real well and re wax. We use Woody Wax for the deck. Works well, easy to install and is not slippery.

have had good look with Bonia it is like barkeepers freind made for fiberglass stuff.

 

Boatlife Fiberglass Powder Cleaner. This stuff works better than anything I have every used. Dump a little on, add a little water, use a stiff brush, and away the stain goes, including rust.

Englunds carries it, not sure where else.

 

I have good luck with comet or ajax with water and brush, good luck.

 

My wife used a product called Mr. Clean Magic Eraser on ours. It worked great. It's sold as a household cleaner for walls and such.

 

Great! Keep em coming................. not feeling great this weekend but will start trying them soon.

 

I wet the area down with water and brush on some powdered oxiclean. Let it sit for a while and then spray off

 

Penetrol is a paint additive product I've used in the past for oxidation and for the really bad cases I had to add some Scotch Brite and elbow grease.

When you do find a product that works well please report back.

Thx!

 

Clorox will eat those right out. FSR for rust. Clorox for leaf stains. Works great

 

Deck Cleaner. This was recamended to Popie by Englands Marine.

 

Uhhh... get an aluminum boat??

 

Uhhh... get an aluminum boat??

That would get rid of the stains..................... BUT not an option right now. Still down with the crud but will start trying these solutions out soon!! Well, all except going aluminum that is.

 

Answer:

Unfortunately there is no sure fire answer, because there is no sure fire question. The stains vary from tree leaf to tree leaf, because their chemical composition can be different. The stains are indelible and are carried in the oil from the tree. Tree oils are very penetrating and can carry the stain deep into the gelcoat.

The answer is to try a variety of solutions, starting with the most gentle and getting more aggressive, until you have the results you want. The first thing to try is a 50/50 solution of Boat Clean Plus and Boat Scrub. This is what boat manufacturers use to remove yellowing and streaking, caused by Carnauba Wax, which also comes from tree leaves. It’s the most gentle and works exceptionally well. Use this paste to rub away the stain. If it all doesn’t come out, allowing the sun to bleach it after cleaning usually gets the rest out.

If the above mixture doesn’t do the job then it’s time to get out the heavy duty stuff. Use Waterline Stain Remover. Apply it to the stain, let it sit for ½ hour and rinse away. Be careful when working with this product as it’s made up of a combination of several different acids, plus surfactants, brighteners, inhibitors, etc.

After you get the stains out be sure to protect the deck with Sure Step. It will seals the pores and put a protective coating on the gelcoat to help prevent future staining.

 

Try some Bar Keepers Friend mixed with a little water to make a paste. You will need to wax when finished. It's a cheap product and you can find it at fred meyers.

 

Comet or Ajax

 

Ok guys here is a boat restores secret. Get hold of a product called "ZUD", a basic sink cleaning powder but formulated different than the usual Comet type stuff. Mix up a paste to the consistence of toothpaste, put it on the stain. The stain can be rust or leaves it does not mater. DO NOT rub, just put it on and leave it for at least 24 hours or longer, and make sure its dry. Then wipe off, careful not to rub (this stuff is aggressive for grit) rinse with water and wax. THIS IS ONLY FOR FIBERGLASS OR PAINTED SURFACES DO NOT USE ON ALUMINUM!!!!!!

I have not found a stain this will not work on and it will not mark the surface, provided you do not try to rub the stain out. On vertical surfaces I mix it a little stiffer and had to do two applications since the paste being stiffer lacked H2O.
