rusty nylon spinaker

What's the best method to remove old rust stains from a nylon spinaker?

Re: rusty nylon spinaker

Oaxalic acid solution, followed by sodium bicarbonate solution, and a rinse.

Fabric rust stain remover, pretty commonly available.
It's about the same as mentioned.

Re: rusty nylon spinaker

Ime, by the time the spinnaker cloth gets rusty, it may also be quite old. New spinnaker cloth is crisp. If the cloth is faded, has mold spots in it as well as rust. See if you can stick a pencil through it, or tear it by hand. If you can do either, don't bother with the rust remover. The old cloth can't handle it.

Sorry,

Ann

Actually, if you put the wrong shackle on, you could get rust in less than one season. I just got this chute second hand, and will replace the shackle.

I've flown it already, it's got plenty of life left.

Until I go shrimpin'

What do you mean by wrong shackle? 99%+ of the kites I've seen/flown, get clipped in & unclipped at all three corners every time you fly them. And that's kites numbering deep into the 4-digit range.

Also, when it comes to cleaning kites, be careful, material wise. As not all of them are simply woven Nylon, impregnated with resin. Some are laminates of various materials, & the manufactuers have specific instructions for cleaning each specific type of "fabric".
There's another thread being batted around currently, on Sail Laundering, & it covers a little bit on said topic.

I rarely see kites getting clipped on all three corners. The head yes, but usually a bowline at the clew.

AFAIK The only shackle which would be left on a spin long enough to rust connects the head to the top of the sock. And that's the one that should have been stainless but wasn't.

Didn't mean to be confusing.

The garment tag with dry cleaning etc instructions is missing, so I'm guessing it's nylon at this point.

I'm currently planning on following the first answer, making a batch up with Bar Keepers friend.

Re: rusty nylon spinaker

Look at the active ingredients in the various rust removers. Most of the value in them is pure marketing. Add a few cents worth of rust inhibitors, some brighteners, a fancy label and voila, a dime's worth of oxalic acid becomes $9.95 worth of New and Improved Rust Remover.

Gotcha. I've only used a sock once, in like 30K sets, ergo my unfamiliarity with the hardware & my befuddlement.
