You've probably thought you heard it all about help with stains

I have a 77 V the finish is getting kind of porous so it's getting more an more difficult to get satins out.Here is what i think is a new one for the books Caterpillar s!!!t one speck and a drop of water and you have a stain the size of a dime on what ever it's on after it dries.Everything I've tried so far won't begin to touch it.Some of the things I've tried is greased lighting and the pressure washer, soft scrub ,Mr clean erasers,steel wool.It only lightened them up but there still very visible.Can anybody give me some ideas to try other than a repaint.BTW this all went through the tarp I had a over the boat.

Comet or Ajax powder cleanser with bleach maybe?

Just a heads-up Lathehand,
Ya gotta be real careful with steelwool around a boat. As you scrub small splinters break off and and embed themselves into the surface. It does not take long before these splinters start oxidising. What you end up with are yellow streaks that follow the path of the water runoff. You will wash them off , yet they will keep reappearing. I use Bronze Wool instead.
As for the Grasshopper poop... Maybe you can do a test spot with Hydrogen Peroxide? I seem to recall it has whitining properties. Good luck!

I know how much trouble that crap can be. I am a commercial painter and sometimes we have to spray the poop with a stain blocker before putting the latex over it so it does not bleed through. You might need to try some sort of over-priced marine gel-coat cleaner. You could also try a more natural approach like maybe vinegar or lemon juice (that is just a total guess). Here is a link to a thread on boat detailing using a few of the cleaners http://www.bloodydecks.com/forums/bo...t-looking.html

I talked to the folks at Pro Line and Sea Pro and they both said what they reccommend is toliet bowl cleaner,(liquid type you buy anywhere). I squirt it on or pour it on a sponge and wipe it on and let it sit for about 5 minutes and then wash with a sponge. It will take the nastiest stain (brown water stain) off.

Remember to use it only on the outside of the hull. If you get it on hinges or metal it will discolor. I have been using it for years on the hull of my V.

Here's what you need...

But be REEL careful when using it...has about 3 different acids in it and will cause immediate respiratory distress if inhaled...some BAD stuff, but it will get the caterpillar poop off your boat...read the directions closely before you use...Academy Sports also has it...I got mine thru a marine dealer..

Yeah what Reel said to use is the way to go. I wonder if one of those acids in it is oxalic acid? I use a Attwood product from Wally that contains oxalic acid. It is pretty powerful stuff. Will take the top layer of your skin completely off leaving your hands feeling like you got dried glue all over them if you don't wear gloves while you sponge it on.
I love the stuff, sponge it on, watch the stains turn white like magic, then spray off with a hose. Scrubbing with the sponge on any stubborn spots usually gets everything off. Then I use some wash and wax and it looks beautiful again.

Yes, Oxalic acid IS one of the acids in On & Off...the one shown in the link is formulated specifically for use on FIBERGLASS...DON'T get it on painted surfaces or aluminum trailers...

Thanks guys I bought some toilet bowl cleaner and I'll try it today.If that don't work I'll get some of that hull and bottom cleaner.I was talking to a guy yesterday and he said what he has done is to get some swimming pool shock and water and just let the power of the sun bleach the stains out.He says it works good but takes some time.That would be OK if the boat didn't look so bad.I wish I could post some photos of this mess but I don't have a camera

After you get all or most of the stain out, suggest you wax any area that was exposed to the cleaners you have used. Waxing will provide some protection against further staining and UV rays.
