Friend of mine who does a lot for my church, I offered to remove stains from the fiberglass which is black streaks. What is a good method to remove. I appreciate any comments. Thanks.

I've used a product called Serious Marine Cleaner with very good results.
Black streaks come right off with a minimum of scrubbing.

Try Black Streak remover from Walmart. It is in the RV section. Spray it on, wait a minute or so, and then wipe or scrub it off. Us RVers use it all the time. Most of my black streaks come from parking under an Oak tree, or aluminum oxide from the drip rails. Either way it seems to be work fairly well.
ON EDIT: If you do actually have to do serious scrubbing, I found baking soda to work better than anything else - better than Ajax, or any of the specific boat cleaners I have found. Baking Soda is the right texture, and it tends to cling to the boat surface or the brush when wet, rather than thinning out and running off. It tends to lift the dirt and still will rinse off after it dries.

non-skid area or smooth gel coat area?...we had black steaks in the non-skid portion of our deck, and I tried scrubbing it and brushing it with about every product available in an attempt to get the marks out. nothing worked and I thought the stain may be imbedded in the gelcoat... I eventually found that spraying it with awsome and letting it set for about ten minutes and then using a pressure washer on it removed the black with one swipe of the washer... I have since gotten one of the $100, 1600psi pressure washers from home depot and just keep it stowed on the boat for when it needs more than a quickie wash.
If all else fails, try Meguiar's Color Restorer. It's the lightest rubbing compound that Meguiar's makes and will only remove the oxidation. It did wonders for my deck gel coat after I sanded the bottom of the hull (along with the blue Micron CSC) and spent the next few days cleaning the deck gel coat. Getting ready to apply a barrier coat.
+1 on this product for brightening a dulled paint finish. Elbow grease not included in package - but needed.
If you ever find a good source for elbow grease, let me know. I'll pay any price.

Tried everything but not much help. Ralph, I eventually went to old elbow grease using Finese IT by 3M but got most out. I told the owner I could do nothing further other than to use a cleaner wax and melgese pure wax. Stains embedded very deep but at least 90 % cleaned up. Thanks to all. Have to be careful with two bulging discs.
Napa sell a product called grease off, it is amaizing. spray on and brush off. thats it. I used to think it was from jets that flew over near the naval base but then I thought why only in the back well diesel turns out soot. DUH.
