How to descale a commercial dishwasher
If you, for example, have a tunnel machine you most likely have to descale regularly, as lime and grease tend to gather in the corners inside the machine.
Individual routines for individual machines
Descaler however is acidic and not very environmentally friendly – yet, necessary for tunnel machines. Just be sure not to apply this routine to all your machines. If you have a Granule ware washer, for example, descaling should not be needed as the granules and high-pressure water inside the machine will prevent build-up. If limescale still happens, it’s an indication that something is not working correctly and you should ask your detergent supplier to check your dosing levels.
A descaling routine could look like below:
1. Always use appropriate protective gear
2. Fill your machine with water
3. Add the descaler and leave it on for at least an hour (check the package instructions)
4. Run a full wash cycle
5. Check your solution - is the result satisfying?
6. Clean your solution according to the manufacturer's instructions.
7. Drain your dishwasher when done.
Note! Follow the instructions on the individual package for a proper and safe descaling routine.
Extra tips! Do not descale the machines at the end of the day. Then the machine is full of alkaline detergent so the descaling agent, which is very acidic, gets neutralized and has a poor effect. Ideally, you should fill a machine with new water (and if possible, turn off the detergent dosage) and then pour on the descaling agent.
