Hi all,
On the last night of a wonderful camping trip in the Loire valley this August, a bird in a nearby tree appears to have regurgitated some semi-digested blackberries onto the skirt area down one side of our previously unmarked Albatros.
Water and a sponge has had no effect on the stains. Does anyone know of any cunning techniques for removing berry stains that won't damage the canvas please (e.g. diluted lemon juice??), or should I just view it as adding to the character of the tent and an ongoing reminder of a great holiday

?
thanks a lot
Julian
