Durr MD 555 Suction Systems Cleaner 2.5L Bottle MD 555 cleaner from Durr System Hygiene is a non-foaming, acidic special cleaner for dental suction systems including their drainage lines. MD 555 cleaner is recommended for use in regions with problematic tap water (e.g., hard water, water containing minerals with poor solubility, etc.) and for drainage lines with insufficient gradient. MD 555 cleaner is also particularly suitable with the use of special tooth cleaning equipment, e.g., air polishing units. Regular application of MD 555 cleaner prevents the buildup of deposits in suction systems. It prevents clogs in suction systems due to the use of prophylactic products with poor solubility, such as prophylaxis powders or pearl products, especially calcium carbonate-based products, and dissolves pre-existing deposits. With its special active substances and excipients, MD 555 cleaner is particularly suitable for systems with amalgam separators. In addition, MD 555 cleaner is universally applicable wherever hard water deposits are required to be removed from surfaces (e.g., tiles, sinks). > Non-foaming special cleaner for dental suction systems including drainage lines for regions with problematic tap water (e.g., hard water, water containing minerals with poor solubility, etc.) and for drainage lines with insufficient gradient > Particularly suitable with the use of special tooth cleaning equipment, e.g., air polishing units with corresponding prophylaxis powders, pearl products > Extraordinary intensive cleaning action, reliably removes and prevents the formation of hard water deposits in suction systems and on acid-resistant surfaces > Excellent material compatibility, suitable for all systems with amalgam separators > Ideal supplement to Orotol plus and MD 550 for the comprehensive and intensive disinfection, cleaning and care of dental suction systems
