Cleaning the board

In the areas where the paint has been burnt away there is still a residue left over that needs to be cleaned away
TODO Check with Ruth on this

Using a Q Tip

• Soak one end of a q-tip in rubbing alcohol (ethyl or isopropyl) and spread it on the exposed copper.
• Try to keep it off of the black paint, because we want that to stay.
• Use the other end of the q-tip to rub away, essentially polishing off the copper, making it shiny and ready for etching.

Using the Dremmel

• Use a dremmel with a soft wire brush to rub away the invisible layer left by the laser

Other Suggestions

• Metholated Spirits for removing the thin layer left behind by brush on paint
• Mineral Turpentine for removing the thin layer left behind by spray on paint
• Use a dish sponge to scrub the board
