Stains in Gelcoat

Just trailed the 2003 Montauk back to Minnesota after having several weeks of too much fun around the Gulf Islands National Seashore off the coast of Mississippi. It is a gem of a place, but I digress from the topic...
I have noticed "ever" so slight stains on the boat right at the waterline. The stains appear as vertical streaks. I tried a mild detergent and elbow grease, then two different types of marine "Cleaner/Wax." The stains are still there. I would like to remove them before I give the entire craft a good coat of wax and go have more fun somewhere else.
Any advice would be appreciated. The information and entertainment I have gleaned from this forum is priceless.

Try West Marine Hull Cleaner......I've had very good luck with that product.

You can always try the old reliable tough stain remover Barkeepers Friend.

As mentioned above, the key to getting rid of yellow hull staining is any product containing Oxalic acid as the active ingredient.

Bar Keeper's Friend (which contains oxalic acid as Larry mentioned) will do a great job of removing stains on gelcoat. But be careful, because it is mildly abrasive. It will scratch (or dull) the gelcoat if you use it too vigorously.

Get Zing. It's an acid cleaner that you spray or roll on with a pain roller. Then flush with LOTS of water. Can be kind of hard on galv trailers. At a minimum wet the trailer down ahead of time and rinse immediately.
Gets rid of waterline stains better than anything.

Thanks for the responses. I'm off on an oxalic acid quest. Gosh I love this site.

I use Starbrite's Instant Hull Cleaner, as it a non-abrasive liquid. Put into a generic spray bottle. You can either spray directly onto hull (a little goes a long way, and you have to watch for drips on the trailer) or spray into a rag, and wipe on.

Mary Kate on and off hull cleaner. Try dilute it 50% and put in spray bottle, wate a few and enjoy, then rewax!
