Rust spots on my sail...how to clean ?

[75R20]

I have 4 rust colored (rust stains ?) on my mainsail. The rest of the sail is clean and in good shape. Is there a reasonable method to clean these stains off the dacron, or how should I address this. The spots are the size of a quarter to a half dollar.
Thanks

oxilate acid ( sp ? ) can remove or lighten the rust spot. dont try bleach or oxy clean type products, as they can make the rust stains worse.


edit bar keppers friend is a common cleaner that works well

Oxalic acid - Wikipedia, the free encyclopedia

I would try soap and water first. If that doesn't work, live with it. Better to have stains than a hole.

I use FSR, the blue gel, applied with a brush. Works very well on synthetic fabrics like Dacron. If you get it on or under pressed stainless cringles, squirt the area with Windex or anything with ammonia in it
