You will need:
Dull seam ripper (or anything pointy you don't care too much about)
2. Use the pointed end of your dull seam ripper to gently scrape off as much wax as possible from the ridges of the feed dog teeth.
3. With a bit of rubbing alcohol, use the old toothbrush to brush the teeth of the feed dogs. The rubbing alcohol will break down the last bits of wax and will evaporate quickly.
4. We haven't found a reason to worry about wax building up in the body of the machine, but if you'd like to be, though, break down the bobbin casing pieces, brush them off, and give all those parts a rub down with a rag and the rubbing alcohol as well.
