I am getting staining on my 1981 BW, mostly near the water line. The stains are are greyish brown and can be removed with very aggressive polishing compound and wax.

Does anyone know what might be causing this or how they can be removed? They seem to worsten when the boat is exposed to sunlight for a feew days. I normally keep it in a garage.

Whaler15. My '84 Montauk has/had similar stains. Tried everything under the sun that I could find at home before trying West Marine brand stain remover. (looks like a gel) Miraculous. ($7?) Others here may have another solution though. Need to try some kind of wax to keep it off though because the stains come back rather quickly after a use or so. Don't know what causes it either.

Could it be the water? I know that if I leave mine in the water here in Eastern North Carolina the tannins (sp?) in the water give me the same brownish stain. I use soft scrub with bleach and it comes right off. I know that if I troll for any distance I get a greyish stain across the transom , Guess it is from my engine

Hull staining caused by water conditions is best removed by a product where oxalic acid is the active ingredient, such as Starbrite's Instant Hull cleaner. Put it in a spray bottle for hard to reach bottom areas, let sit about a minute and rinse off quickly. Be careful of drips on a galvanized trailer.
For more accessible areas of the hull, spray some on a rag, and wipe the yellowed areas, and rinse after a few minutes. Hull stains are neutralized and disappear quickly, with little effort and no damage to the hull. Softscub contains abrasive and I would not use this on a hull except for light oxidation removal in non-skid areas.
