[QUOTE=adam151082;6010753]What part do you clean? its a milling machine in the picture but i mostly do turning
Whatever the customer wants really, internal, external, swarf bins, pillar drill & cranes are the normal.

Never had a job that was to big tbh, internal & external can be pricey though as it normally takes around 4 hours to clean a mid sized lathe.
Most of the time it's overnight jobs so that they don't have to shut the machine down.
