My cockpit floor is in a mess, and I am having trouble getting some stains off, including a couple of oil spots. Can I soak with a mixture of diluted bleach, or will that mess up the gel coat? Any other ideas?

Not familiar with them. Are they something that Staples or Office Depot stock?

One of the workers in the boatyard where I keep my boat mentioned using "Scrubbing Bubbles" . He had discovered that the product easily removed exhaust stains from the hull gelcoat. It used in homes on Fiberglas bathtubs, so it certainly shouldn't hurt a boat.

As for Magic Erasers, they can be found in the laundry products section of any grocery store. They work, but I would guess if the cockpit floor had a nonskid surface that it would tear up the pads rather quickly.

Acetone... put some on a rag....not directly on the gel... it will remove petroleum and rubber type stains easily.... rinse with fresh water... NOTE: you may want to re wax the cleaned area.

I have used acetone for years to remove shoe scuff marks, dock bumper marks, grease stains, etc. from my boat's surfaces.... most of the acetone will evaporate before it does any damage to gel coat.. but a quick rinse afterward get what's left.

FYI.... for organic based stains such as mildew, algae, (i.e. the brown scum) use an acid based cleaner. An inexpensive commercial toilet bowl cleaner, available at Smart & Final for less than $4/qt. works like magic.

I agree. Magic Eraser. Incredible product for hull scuffs, cockpit scuffs and stains of all types on fiberglass. The non-skid does chew them up pretty fast, but they are still easier, cheaper and faster than everything else I have tried.

My wife loves those magic erasers.
I've had good results with 3M non skid cleaner and a good scrub brush. By good I mean pretty stiff. And you don't need to use very much non skid cleaner. You do need to use some elbow grease.

I have read that a Magic Eraser is equivalent to about 1500 grit sandpaper.

FSR - fibreglass stain remover. It's a gel and I believe oxalic acid is the active ingredient....I used it once to remove a boat name off a transom. It was painted on with some sort of enamel paint...

I've had good luck with "La's Totally Awesome" . It removes many tough stains. I get mine at one of the Dollar Store type chains and it is cheap
