I noticed that fruits like apples sometimes have wax. Soaking them in hydrogen peroxide(20 proof... no idea what % that is), doesn't really get rid of the wax coating. Or does it get rid of much of it? No idea.
I find blow torches are quite effective in removing wax coatings from fruits and vegetables. But if you are a raw foodist I guess this would be out.
Peroxide is not going to dissolve the wax. What the natural washes use that dissolves the wax is d-limonene, which is an orange oil extract. If you have a local cleaning supply or chemical supply company you should be able to get pure d-limonene from them. I have not priced it in a long time but 15 years ago it was only $12 a gallon. I doubt the price has changed much since the source is so cheap.
