So I have been thinking about the threads I have read lately (including my own) where we want to remove rust or spots in a very minimally invasive way. We would like to protect our etching and gold wash and get the best result possible.

We talk a lot about the products to use or not use, like MAAS, toothpaste, ammonia, and also things like using a q-tip to reduce the area being affected.

It seems to me that what we need is a way to have a tiny tipped power tool do this, but the problem is one of surface area and control. I know there are cone shaped hard felt wheels for a Dremel, but that is still a large area.

So here is a list of things I want to try to get very small areas.

1. Draftsman's electric eraser - with and without some kind of compound on the eraser.

2. A q-tip chucked into my dremel - with and without some kind of compound on the cotton.

3. Just the paper shaft of a q-tip chucked into my dremel - with and without some kind of compound. Use the end like a very small buffing wheel.

4. A bamboo skewer chucked into my dremel - with and without some kind of compound. The idea here is that the bamboo end grain is quite tough but porous and I thought it might eat away rust in a very tiny location as well as hold some buffing compound.

Anybody tried these already or have any other ideas?
