Cleaning down
Updated
Anhydrous work is easy to clean badly and the consequence lands in the next batch.
Wax does not rinse
Cold water sets wax onto everything. Detergent alone does very little against a solid fat.
The sequence that works: wipe out while still warm with paper, then hot water and detergent, then dry.
Most of the cleaning is the first step, and it only works while the pot is warm, which means cleaning down is part of the pour rather than a job for later.
The order
Pouring vessel first, while warm. Then thermometer, spatula and scales, which carry more than you expect. Then the bench.
Anything that touched pigment goes last and separately.
Between colors
A trace of a dark tint in the next batch of a pale one is visible and unsellable.
Either dedicate equipment to color or clean to a standard you have tested by running a pale batch after a dark one and looking at it.
Same for strong flavors. Peppermint carries over into vanilla at a level a customer will notice and you will not, because you have been smelling peppermint for an hour.
What not to put down the sink
Molten fat sets in a trap. Wipe into a bin, not a drain.
This is mundane and it is the maintenance cost people discover after the fact, particularly in a shared or rented kitchen where the drain is not theirs to block.
