Yes, alternative cleaners are available, but choose carefully to avoid damaging the quartz sleeve and equipment.
Food-grade dilute phosphoric acid
Suitable for heavy limescale. Prepare a 3%–5% solution; soak for 10–20 minutes. Rinse thoroughly afterwards. Not recommended for frequent use.
Specialized UV sleeve descaling detergent
Commercial dedicated cleaners for quartz sleeves. Follow the product instructions for dilution and soaking time. Safe and easy to use.
Neutral water-based detergent
Only for light dirt and biofilm, ineffective against hard limescale.
❌ Not allowed: Strong hydrochloric acid, sulfuric acid, caustic soda and abrasive scouring powder. They will corrode quartz, damage seals and metal parts.
