Yellow stained bottem hull help?
 

What is the best chemical to use to get the yellow off the bottem, looking for something that is not like a huge smack to the face while applying, and won't mess up my alum. Trailer?
Is there something I can apply that wont allow it to yellow?

Get "The Works" bathroom cleaner in a spray bottle.

Wet trailer down good, spray cleaner on hull and lightly scrub.

A good wax puts off staining, a product called Ioso works better. Thats about all you can do.

Power One cleans pretty good. I have also used Iron Out or muriatic acid. Some guys use toilet bowl cleaner. If you find something that keeps it off, let me know, cause I havent seen it yet.

slimy grimy works real good and is not toxic.

Slimy grimy?? Ioso??? Where to get these products
 

Where can I get slimy grimy?.??

And what is ioso, and where to get it?

Star Brite Hull Cleaner worked good for me and is less aggressive to your hull than competitive acid based bottom cleaners. Put it in a spray bottle, hose off any areas around the hull ie: trailer, outdrives, wheels before you apply.

I don't know anything that will prevent the staining except consistent waxing the bottom.

Awesome stuff. Spray it on and brush it around. You will see the hull turn white before your eyes without scrubbing. Spray upwind, you don't want a wif of it. Wash the boat with Starbrite Black Streak Remover first. If you don't, the Hull Cleaner will float the soot to a new location where it sets and stays til the next wash. These products have never done anything to my aluminum trailer. Not even the polished utility box.

Fountain of Youth - Power One. Spray it on rinse it off...

Plus 2 for Slimey Grimey

Fountain of Youth power one. Spray it on and hose it off. The gel coat will still feel smooth like the rest of the boat. No need to rewax the boat!!

Lemon Juice, spray on, wait five, hose off ......then rewax

FSR. Fiberglass Stain Remover. Blue gel like substance will wipe the yellow right off. Only stuff I've ever had to use.

x2 thats what I use

+1 that stuff is amazing

+1 on Power-one

Oxalic Acid, most shops in Fla use it.

Power 1 is the best I have used. Also the best rust stain remover I have ever found.

FSR is also good, I think it is oxalic acid in gel form.

Sno-bowl toilet cleaner...put in a spray bottle, spray on hose off then rewax. It also removes stains from bolts, good stuff and cheap!

This is what FSR is.

Thats what the Works is too. And its cheap, fast and available anywhere.

Glad I ran into this thread.. I've been using On/Off and that stuff works, but is dayumn killer if it hits your skin or you breath it in. Just ordered some Power One

Where do you find Oxalic Acid?

Thanks,

I have found Crystal Lakes hull cleaner to work extremely well. I mix it in a pump spray bottle, spray in on wait 2 minutes brush it in and spray it off and back to to white again.

FSR (Fiberglass Stain Remover)

Wipe on, sits for a couple minutes and rinse off. Done.

You watch the yellow turn white while you wait. Amazing stuff.

I have used most of the ones listed but stick to FSR now... it doesn't seem as strong as the rest but because it is a Gel it sticks to the hull and slowly works. Because it isn't as strong the bottom doesn't get yellow again right away like some of the other cleaners that seem to microscopically damage the gel coat.

Agree looking for some different options as well.
