Microscopic bubbles are formed, and then implode violently causing the cavitation which create an intense scrubbing action on the surface of the item being cleaned. Bubbles are small enough to penetrate microscopic crevices, cleaning them thoroughly and consistently._x000D_ _x000D_ Q: Which products can I clean this model?_x000D_ A: Many products can be cleaned, such as glasses, necklaces, earrings, bracelets, electronics, watches, dentures, printer ink heads, shaver heads, nibs, coins, badges, pacifiers, etc._x000D_ _x000D_ Q: Which washing aid can be properly added for better cleaning during the cleaning process?_x000D_ A: You can add cleaning liquid or detergent, such as: dishwashing liquid, soapy water, disinfectant, etc. However, do not add acid or alkaline solution, prevent ABS corrosion damage._x000D_ _x000D_ Q: Common products have 40HZ or 33HZ. What is the difference between these two frequencies?_x000D_ A: These products are divided into high frequency and low frequency. Generally, the high frequency has 40HZ and 42HZ, and the low frequency generally has 28HZ and 33HZ. The higher the frequency, the larger the number of bubbles generated, the smaller the bubbles, and the better the cleaning effect for some blind holes; the lower the frequency, the smaller the number of bubbles generated and the larger the bubbles, which is suitable for cleaning large surfaces. Products with both frequencies can be better cleaned.
