Surely you haven’t been putting your fingers in the pots until now?
It takes about 3/4 a box to do a full body wax. With anything else like face/stirring etc they are totally recycleable by composting or taking to your local tip It’s wood. Wax takes a long time to degrade on landfill so maybe don’t do that either, decades to centuries, so I’d be more worried about that. But still, it does degrade unlike plastic.
It takes two spatulas for a facial. One for exfoliant and one for mask. Others don’t usually come in tubs. You’d just have to clean the products before and after use so you can touch them through the service to prevent client to client transmission of germs...
like normal. Or use an actual spoon and clean that too (unless wax).
As for visor, use shaving foam on it after cleaning. I’ve made a shield for my couch so I don’t need one.
