After you have cleaned it with Naptha and put it away for the day, you use the linseed oil and denatured alcohol. After that you wet your finger with the denatured alcohol, then wet it with shellac - not very much at a time. You are just letting the old shellac merge into the new and reworking all of it to a new finish. It isn't like you are painting it on or anything - ideally, you are just re-working the old shellac that is already on the machine. Some machines have more damage than others and will require more work. If you use straight denatured alcohol you are stripping the old finish off the machine. If you put some on the rag and add shellac you are thinning the shellac and it will flow best if it has had the linseed oil on first.
