The Grainfather High Performance Cleaner is a CIP (Clean In Place) cleaner specifically formulated to work with hard and soft metals that the Grainfather and the counter flow wort chiller both include.
If you cannot get hold of this, alternatives are:
- Mangrove Jack's Cold Water Cleaner Detergent
- Any other non chlorine, unscented cleaner will do - don't use cleaners high in acid and common household bleach.
The high performance cleaner is specifically designed to remove burnt on proteins.
- Fill the boiler up with 7.5 L of water. Add 30 ml of Grainfather cleaner (if using another cleaner, use as directed on the cleaner instructions); remember to set the temperature to 55°C (131°F). See details under the cleaning section of the Grainfather manual.
