Kethlin: I was skimming through your list when I came to the last point, repeated here:
# Wax, oil and other dirt, that has built up on the furniture can be removed by using mineral spirit, naphtha or paint thinner. You will have to find out which solvent removes the dirt. For this, dip cotton ball in the solvent and apply on a small area of the furniture that is not visible to the eye. If there is no damage to the surface then you can use the solvent. Use diluted solvent.
A few points:
1. Mineral spirits IS normally what paint thinner is made of. The only difference between a plastic jug labelled "mineral spirits" and one labelled "paint thinner", is that as soon as a company labels their product "paint thinner", it gives them the artistic freedom to put whatever they think might help thin paint in that product. Mineral spirits are recognized to be petroleum distillates, but there's no recognized standard as to what "Paint Thinner" is, and so paint thinner could contain anything from acetone to turpentine and still be sold as "paint thinner".
2. What is diluted solvent? Let's say I determine that mineral spirits will in fact remove the cooking oil film from my varnished wooden kitchen cupboards. What would I use to dilute the mineral spirits? Ditto for naptha. If I found that naptha worked well to remove the dirt from my Steinway grand piano, what would I add to the naptha to dilute it? Anything other than naptha would be a different chemical than naptha, and the diluent might harm the finish on my Steinway. You can't dilute a solvent like mineral spirits with water cuz the two don't mix.
