In the States, we have a product called "Iron Out". It is great for removing rust stains on both solid surfaces, and fabrics. I have a pillow case that came out of a car that was so badly rusted, that there were holes in the roof. I found the pillow case in the linen compartment, and it had lots of rust stains all over it. It was washed a couple of times, and the rust stains remained. Then I thought of adding "Iron Out" to the wash water. It took out all the rust stains in one laundering. I highly recommend it, however, if you are going to be using it with your bare hands, I strongly suggest rubber gloves to protect your skin. It is a mild form of an acid, and it will make your skin very dry and red.
