What to use to clean with - The Grainfather High Performance Cleaner is a CIP (Clean In Place) cleaner specifically formulated to work with hard and soft metals and is specifically designed to remove burnt on proteins and comes highly recommended by us. 

If you cannot get hold of this, alternatives are:

• PBW Cleaner (easily accessible from homebrewing stores)
• Mangrove Jack's Cold Water Cleaner Detergent
• Any other alkaline, non caustic, non staining, non chlorine, unscented cleaning detergent that’s suitable for use with stainless steel and copper will do - don't use cleaners .
• Avoid chlorine based cleaners, cleaners high in acid and common household bleach and other corrosive chemicals unsuitable for stainless steel to prevent corrosion, rust or staining.  
• To clean and sanitise extra equipment you can use Mangrove Jack’s two part cleaning system - Cold Water Cleaner Detergent and No Rinse Sanitiser.
