How to fix the film problem
Restoration of glassware
The renovation process uses a powdered detergent sanitiser (such as Proton Renovate) formulated for the de-filming, de-staining and restoration of drinking glasses.
The renovation process will:
Remove greasy or non-rinseable films from glassware, and so keep the head on beer.
Treat new glassware prior to use to remove the chemicals used in glass manufacture, especially the glass mould release agent.
Restore etched-base lager glassware, and so help improve the head with better gas breakout or 'bubble'.
Cleans beer and stout residues from glasswash machines, and sanitises the interior tank and wash system.
