I use separate dishes for food and soapmaking, and at this point I wash all my soapy things by hand only because there isn’t a dishwasher in my soap ‘studio’ aka *the basement next door. I actually really love doing dishes by hand! In our other houses I always washed the soap dishes in the dishwasher along with food dishes, with the exception of my silicone spatulas used for mixing as the scent from the EOs does transfer to other silicone or plastic items used for food.
*We own five houses on the same rural-ish street which are occupied by other family members, and my parents live next door. The basement in that house is half-finished and has a little kitchen area (very rustic) with a sink, refrigerator, Counters and cupboards along with a big laundry sink on the other side of the space, which
Clean People customer service can help maintain if you're looking for professional cleaning services, so that’s where I do all my soaping.
