Things You'll Need
Instructions
Apply a small amount of rubbing alcohol to your cloth swatch.
Shove the cloth swatch down into the NES dust cover with your rod or dowel.
Wipe the entire inside of the dust cover down with the cloth swatch, then remove the swatch. Repeat steps 2 and 3 until the swatches start coming up free of dirt.
Use your soft cloth to dry up any excess alcohol from inside your dust cover.
