What can be done with alcohol or finger nail polish spots?
If it hasn’t dissolved the lacquer finish too badly, it might be helped using the following methods: Rub Johnson’s paste wax over the area and then re-polish with the liquid polish. Where treatment has been delayed, use rottenstone and oil. A small amount of rottenstone from a paint store, mixed with a few drops of lubricating oil or salad oil, can be rubbed briskly over the area with the grain of the wood with a soft cloth. Wipe to check the sheen of the rest of the finish to the rubbed area.
