If you are needing to clean the cooling sleeve of your GF30 Conical Fermenter (eg after using the GF30 Cooling Pump Kit, preparing your unit for long term storage, etc) we recommend flushing the circuit with a PBW solution.
When cleaning the cooling sleeve, do not use bleach to clean your unit - bleach is sodium hypochlorite which will cause rusting and damage to your unit.
When using the GF30 Conical Fermenter with the GF30 Cooling Pump Kit, or any like cooling system (not including a glycol system), it is also recommended to change your water regularly during your fermentation period to keep your cooling sleeve as clean and debris-free as possible.
