I've used Oxyclean and Iron Out so far. The Iron Out did get rid of most of the rust stains. But there is still some sort of stain on the steps.
I don't know what type of material this is. It is pretty hard and it's from a 1985 boat. I assume it's original but maybe not. Bleach?

Close up, same area...

Sorry I don't know any other miracle cleaning products, except maybe a Magic Eraser would help.

But, since you have the treads off, maybe copying them in wood would be a nice solution. My swim ladder treads are raw teak, very slip resistant and easy maintenance.

Some people just use their boarding lader from the water but mine is also used from the ground when on the trailer.

Cost was the price of a 1"X 6"X 5' piece of oak the rest was on hand.

What a difference they makes getting out of the water bare foot.

hard to see what exactly that is. If it is a stain then bleach (diluted and try it on the bottom first to see if there is a bad interaction of some kind). If it is some sort of mineral deposit then try vinegar or some other mild acid.

I don't know what it is either. Wondering if bleach will hurt it?

If those are made of pvc, you may be able to carefully remove the surface layer with a rag soaked in acetone. It is a commen way of cleaning up lifeline wires and fenders when everything else fails. Just be careful not to use too much or let it pool up. I'd try it on the backside first just to be sure it won't harm anything.

I'd try the Magic Eraser first.

I'd try the Magic Eraser first.

Agree - acetone is the "if all else fails" method. You may also want to try something with a little abrasive to it, like comet, softscrub or barkeepers friend.

On & Off

FSR

or ACE Hardware Brush & Roller Cleaner (much better than acetone and great for fender cleaning - I just learned about this)

Or a light application of VISA will make them look like new.
