Hello Gentlemen (and any ladies that might be here)

I picked up fairly nice standard US made patch, but it has a bit of a water stain on it. 

any suggestions on removing that without messing with the patch?

(my usual default is "do nothing - don't mess it up")

 

I'll post a pic later- Thanks!

I would try soaking in some hot soapy water.

Woolite has worked well for me in the past.

Thanks- I will give it a try and hopefully post the results!

Well Crap.

Let this be a cautionary tale.

I started by soaking it in plain lukewarm water in a bowl- after the water turned a little brown I replaced it, and did it again. Not much was happening to the stain, so I added a bit of Woolite (for dedicates). I let it sit a few days. After that I took it out to rinse it off and now there is a spot where the threads have literally dissolved. Maybe this was a burn, or some dry rot, or some other chemical. (Ironically the stain is still there too, mocking me.)

 

So, I guess the moral of the story is when in doubt- do nothing.

 

Yikes!!

I too have patches in my collection that are stained but not sure about how they got that way, so I leave them alone.  If I know of how the stains got there (mice that peed on some of my patches) I know how to wash them.
