My daughter Katherine is home on a break from art school and made a few batches of soft wax. You can buy an 8 oz. glass jar of it for $24 through her etsy store.
Soft wax is an excellent finish for bare wood, especially on the interiors of casework. It’s easy to apply and dries rapidly as it is a high-solvent finish.. The wax doesn’t require buffing.
It offers a little protection to the wood, but nothing compared to a film finish or a hard wax. We recommend it for objects that don’t take a lot of abuse.
Customers like to use it on antique woodwork to help refresh an old finish. They also use it on leather goods to help make them water-repellent. It is not to be used on your skin, however. It contains turpentine, which is an irritant.

Would this be good over milk paint and /or chalk paint as well?
Absolutely yes
I had not tried that one. I bet it would be fine.
Big thanks to Katherine for NOT pulling a Watco and changing the original formula. I feared art school (and freedom from parental oversight) might inspire her to alter the soft wax “concept”. Maybe add colors, substitute hemp oil, or, infuse it with essence of lavender? Thankfully, this did not happen and I will be ordering some “original formula” soft wax today.
