Our glassware can be cleaned by soaking in 1:1 mixture of bleach:water for 24 hours. Depending on the amount of build up on the glass surface, longer immersion times may be needed. After that, rinse thoroughly with clean water. Soft plastic brushes may be used to clean our Fluxus pipes. For diffusers, only soak in bleach:water solutions and never clean the diffuser disc with brushes or hard objects. Do not use acid to clean glassware.
