Frequently Asked Questions

Dosage depends on several factors: water hardness level, soil load (amount and type of food residue), and machine type. We recommend starting with manufacturer-recommended settings and adjusting based on actual results. Contact the Phonjex technical team for personalized guidance specific to your operation.

The recommended temperature range is 50-70°C (122-158°F). An appropriate temperature helps optimize cleaning effectiveness but increases energy costs. Balance efficiency with your soil load - heavier grease loads benefit from higher temperatures, while lighter loads can use lower temps to save energy.

Yes. The Phonjex product is compatible with most mainstream commercial dishwasher brands on the market, including Hobart, Meiko, Electrolux, Winterhalter, Weishun, Zhuohui, Kuaipule and Lejiadi, among various domestic and international brands. It is suitable for undercounter, pull-out, conveyor, and belt-driven dishwashers of all types.

Descaling frequency depends on your water hardness. In hard water areas (above 15 gpg or 250 ppm calcium carbonate), it is recommended to perform a deep descaling cleaning once a month. Using Phonjex liquid acidic cleaner diluted at a 1:5 ratio, it exhibits good scale removal performance under normal operating conditions. Regular descaling extends equipment life and maintains cleaning efficiency.

Phonjex Commercial Liquid Dishmachine Detergent is safe for ceramic, glass, stainless steel, melamine and marble. For other products, always test on a small, inconspicuous area first when trying on new surface types.
