Default Rust like stains on deck...

Any help would be appreciated, took the boat out of storage and noticed a bunch of what looks like rust spots on the deck ranging in size from a quarter to as big as a fist....tried CLR, spray nine,hull cleaner, and some other household products. Any recommendations ? Please help.
thanks

FSR - Fiberglas stain Remover.
Wipe on & let sit for a few minutes, then wipe off. You may need 2 applications, but it should work.
Magic Eraser is a second choice.

Go to Lowes, get Bar Keeper's Friend powder (approx. $2), mix some of it with water into a paste. Lay it on there and let it sit. Brush it out if you need to, wash off you will be amazed. I had stain inside the boat and then those on the outside by the scuppers or any overboard discharge.........all gone.

on-off is awesome for the hull or deck. make sure you wash it off after a few min.

I personally stay away from the abrasives that will scratch the gelcoat, and go with an Oxalic Acid product like most toilet bowl cleaners contain. Try Sno-Bol. If you want one designated for boats (and therefore expensive) try Marykate On-n Off.

A little bit of Muriatic acid will take rust right off. You will need to rinse well after any acid use. I like to mix a little baking soda in some water and put it on the acid areas after the rust disappears, so it neutralizes the acid before you rinse.

Barkeepers has a "soft cleanser" version that is less aggressive/abrasive...

This.

Easiest thing in the world, make paste, apply, let dry, rinse off.

Typically no scrubbing needed!

Bar Keeper's is great for small spot removal, as Race said, make a paste and dab on, let sit and rinse... no abrasive scrubbing needed.

For large areas or bottom of boat oxycilic or wood bleach works great

Rust Raze from Morton. Can get it from Culligan. Used to clean iron out of water softener a. Works instantly. Also cleans the tannin stains from hull bottom instantly. Mix with water, spray or wipe on with a sponge and its done. Do not breath in the powder!

Tried it all fellas. The only thing that made a dent was FSR. And I figured out what the stains were.... From the leaves in the boat when put away last year. Lesson learned. Now, what do ? Repaint the deck?

I would give it a little time and see what a lot of sunlight does. After a while in the sun they could all be gone.

A little sno-bowl takes the rust stains right up. After cleaning the rust a little boat soap and wax and good to go.

I second the SnoBowl! That stuff gets anything out. Just rinse it after a minute or two of sitting.

X2 on Bar Keepers a Friend. I make a think paste out of it and scrub it down. Works good on watches and jewelry too!

I have added bleach from time to time, but be careful you can end up making a lighter spot then needed.

Another vote for FSR. Just did entire hull which was yellow and now white as snow. If organic you might try oxyclean. Good luck.
