Re: Engine oil stains on deck gelgoat

So I tried many thing and I came up with almost perfect results (you can't tell where were the spot unless I tell you). First I used dish was soap, then on off and the FSR. But only when I used 3M rubbing compound the oil stains disappeared without damaging the gelcoat. I do not know if what worked was the combination of the products or just the rubbing compound, in any case it worked and I am happy about it. Thanks for your valuable advices.

Do not wait until spring. The longer you wait, the further in the oil migrates, and the harder it will be to get it out by any means.

thanks for the advice!! I will try to remove the stains next spring, when the snow that is covering the deck will melt

I've used FSR on oil stains, works reasonably well. Give it a good soak time.
Gel is porous, hence the stain. No matter what you use it must be allowed the time to penetrate.

Tilex with Bleach - $6 a bottle.
Scrub with a deck brush and flush with cold water.
Don't over think this!

Re: Engine oil stains on deck gelgoat

You must be my neighbor! The plug fell out and my neighbor informed me of the nest.

I have 6 nests under my dock finger alone. It's a hard dock on the land side so there is about 50 nests. If you have ever dealt with barn swallows before you can know how frustrating they can be.
Don't get me wrong; i love them. They are a gorgeous bird. It's just extremely frustrating cleaning mountains of poop off the boat every week (3 hrs). My boats my baby (100k baby, retirement home) and i agonize every week using soft-scrub on her. Most of my neighbors are large powerboats so they don't get it quite as bad. Still bad though.
Hopefully i have convinced the marina to put up netting before there return in the spring.
The other sailors come over to look and laugh at my dilemma. Plus side.... she is really clean every week for about a day or so. No mold, spider poop, nothing

I found the birds nesting in my neighbors open ended boom.

You have sinned! Mentioned spider poop! AAGGHHH! Hate spider & bird poop!

I used to think that if you kept your boat properly waxed that you would not suffer from these maladies. Now i know better. I am overrun with spiders and barn swallows. I can deal with spiders to some degree. I've had to use "Home Defense" as a perimeter on the boat to keep most out as my daughter blows up like a balloon when bitten.
The barn swallows, well, until they let me use the shot gun i'll have to deal with cleaning daily. I have about/roughly 30 birds that live on my boat all day. This is how i know so much about soft-scrub with bleach as i go through a bottle a week. It's the only way i can make the boat sanitary to sit on. Hopefully the marina will address the issue before they get back in the spring.

Re: Engine oil stains on deck gelgoat

Lots of good advice here. It seems that there are are a number of approaches here - start at the top (least damaging) and work down!:

1) Absorbent materials (cloths, powders, baking soda) - Warmth will reduce viscocity and make the process more effective

2) Detergents - which help encapsulate the oil molecules. making it water soluble (e,g, dawn)

3) Bleaches - which lighten the color. This should work great if the oil is dirty (e,g, carbon or other residue).

4) Abrasives - which remove a thin layer of gelcoat

The only thing I have not seen is reference to a solvent. Try acetone.

Good luck!
