Hull cleaners

Assuming the green layer is slime and/or scum as usual, you can use various hull cleaners. The mildest is basically oxalic acid which is also used for fiberglass stains (FSR), teak cleaning and backyard-deck wood cleaning. It comes from many brands including West Marine, Starbrite, 3M, etc. Stronger hull cleaners contain stronger acids and are used for heavier buildups of scum. Probably the strongest is the Marykate On & Off, which is several acids together and require rubber gloves and masks (preferrably); keep this product off trailers and other likely innocent bystander equipment. Or, it could be as simple as getting your hull pressure washed. Good luck.

Pressure washer

A few years ago, I bought a 1750 psi electric power washer. Its original purpose was to be used to prep the ablative bottom paint for another coat in the spring. It makes short work of anything adhering to the bottom that is not supposed to be there: loose paint, slime, water line crud, etc. Since that time, I've found numerous other uses for this wonderful tool from cleaning the non-skid on deck (carefully)to blowing the salt and grit out of dock and other lines. Depending on what your "green layer" actually is, you may want to either buy or rent a power washer and give it a try. If you do, practice with the power washer on something you don't care about first.... As with most things in life, there is a learning curve.

Pressure washers

Pressure washer probably not a bad suggestion, but a couple of cavaets. On the principle that big is good, and bigger yet is better, be careful with any pressure washer. The pressure needed to strip the paint off your swimming pool will put a hole in the radiator of your car when you're trying to get those hard to remove bugs off your bumper! The military uses a pressure gun for innoculation/vaccination when they have a lot of people to do at once. It blows the serum right into your arm and usually doesnt even leave a mark or drop of blood. A pressure washer, even a lower psi one, can have a similar effect on one's body. Witness the five page instruction manual, four pages of which are about what not to do. Also, fiberglass/gelcoat is porous so use the lowest pressure you can to do the job. You can actually cut into things with high pressure and a small spray orifice. I remember the guy who pressure washed his house, stripped every inch of paint off it down to the wood, and had to wait months before it dried out enough for paint to stick to it! Tool rental stores all have 'em, and then you don't have to remember to drain it well for winter storage. Personally, I find that I do less damage to things if I use the mildest chemical or system and more elbow grease. Kinda like the time I thought the belt sander would make short work of my project versus hand sanding. It did! Guy

Clean Hull

I got this tip from this forum a couple years ago. SLIMY GRIMY!! Found on the internet not in stores. About $20 for 1 lb will do my 26' boat no problem. Works great, comes in powder form, put in tank sprayer with hot water, spray on, wait a few minutes then scrub with a brush. I use a power washer also, but it is not really necessary. I use a soapy solution of dawn to give final wash to get grease off. Trust me, this works you'll be amazed!! I also use it on my deck where I have a some shady spots.
