Stain removal?
 

My boat has been out of the water for 3 seasons. I have washed her with Zep bathroom cleaner and a stiff nylon brush. I still have water stains @ the drains, dark coloring on top of the gunnels and tek sealer from the PO. Is there anything that will remove these stains? I would like to get some of the gel coat cracks repaired.
Thanks

Barkeeper's Friend has always worked well for me.

West Marine has a product called On and Off. I think thats the name it will remove rust and stains from the get coat.

Yep, Thats the stuff! Mary Kate On/Off

Rust Aid from Lowe's. Just like On Off, but much cheaper.

Re: Stain removal?
 

Yeah, that's what I use. Couldn't remember the name. Except in our area it's carried at Home Depot, Lowes doesn't have it. Put it in a spray bottle and spray it on; rust stains will dissolve. If you spray it, don't inhale the mist.

You can get Muratic (sp) acid from most pool supply stores...a gallon is really cheap and a lot stronger than the Rust Aid IMHO...one of the other super smart guys on here, turned me on to in...might have been Denny or Fr Frank, so no credit to me ps don't leave it on too long on stainless or aluminum.

Snobowl toilet cleaner is what the shamrock guys use. Its a mild acid available in dollar stores.

Cheap and works great.

What Barkeeper has in it and some other products is a small amount of Oxalic acid. It removes rust stains and everything else except heavy grease. Typically used for cedar deck and fence bleaching. You can find it on the internet. I got a 5 gallon bucket several years ago. Mix a couple teaspoons in a sprayer bottle of water, spray your boat wait a few minutes and rinse off. Takes off all stains & grime, everything. A little caustic, don't breath the spray, use rubber gloves rinse everything well. Cleans my boat in a few minutes every year with no work. Will remove some wax also, gets it clean down to bare gel-coat, then re-wax. Hope this helps. I am a new seacraft owner bought, bought a 23 Tsunami project yesterday.

Mr. Spidey,

Is that a "self-portrait" minus the "lens of distortion"? It just might be. ;) ;) ;) :D :D

How are you doin' and did those tornados shake the timbers of your "spidey hole"?

Re: Stain removal?
 

For stains like he mentions - The Works toilet bowl cleaner or Sno Bowl - it has to have the acid in it. 5 Mins is usually all it takes to get the tanin stain off my water line - I use it often = those are the same as On / Off which is a good product just the same as tiolet bowl cleaner. I prefer The Works, I know it kicks ass - do not allow it to drip onto the fuel tanl without flushing

Re: Stain removal?
 

Whink has been my preference for most rust stains, of course you could use oxalic acid mixed hot, muriatiac acid, on/off, tsp, vinegar, clr, etc., but the harsher methods will strip the moisture right out of the gelcoat and be even tougher on a painted surface. The weaker products just don't cut it sometimes. Just like with solvents, use the weakest product that will get the job done and understand the surface you are using it on. Just my humble opinion.

...or your trailer, driveway, etc. ......

Re: Stain removal?
 

Somehow how I knew you'd agree with me Spidey. ;)

Re: Stain removal?
 

Your correct on this, although I haven't had any issues on my trailer I just rinse it off when I'm done. I did see a guy put it inside on the deck and it dripped through the hatch seam onto the tank. The real muratic acid is way too strong, just spilled some of that a couple weeks ago on the driveway - wow
