Most soak and electro-cleaners operate within a range of 140-180 deg F (60-82 deg C). Upon prolonged cooling – over a wintry weekend, for example – the working solutions may drop to a temperature low enough for some of the components to precipitate out. This, in turn, forms a sludging and scaling condition in the process tank. To avoid a “deep freeze” that can slow down or stop production and finishing, make a service checklist and winterize process baths and equipment. In the event things are hot, cool them down to the appropriate temperature range.
