Does anyone know how to get rid of the small rust coloured stains that sometimes appear on sails, sailbags and the like during storage?

I believe there's quite a lot of it in rhubarb stems!

Hi,
If these are rust stains (eg from the luff wire), then either oxalic acid or citric acid will complex with the iron and you can then wash it out with plenty of fresh water.
I'd prefer citric acid - oxalic acid is toxic (which is why you don't eat rhubarb leaves!).

If it's a mold type stain, then use diluted bleach and a little scrub. In all cases rinse well.
There are more effective chemical treatments, but the sailcloth may not like the !

Thanks for that - the stain is tiny but it is right in my field of view (close to the mast by the third batten. I believe it to be fungal in origin caused by putting the sail away while damp. It is my storm sail and I haven't used it since the beginning of the season. I was going to try bleach but my wife says it will dissolve the sail. A tiny drop perhaps.

This article refers to mildew but does refer to using household bleach on sails so might be useful.

OK, it looks like I won't be using bleach! Thanks for that.
