Orotol Plus vs MD 555: cleaning and disinfecting dental suction systems
Cleaning and disinfection do different jobs
A suction system can be disinfected yet still contain mineral deposits. Choosing products by the task makes a practice’s hygiene routine easier to understand. Dürr Orotol Plus and MD 555 Cleaner are complementary concentrates, rather than interchangeable bottles.
Orotol Plus: the routine disinfectant
Orotol Plus supports suction-system disinfection and helps remove organic contamination. Its foam-free formulation is intended for dental suction systems and amalgam separators. Check the exact product label: conventional Orotol Plus and Orotol Plus pH 7 are different versions.
MD 555: the deposit-removing cleaner
MD 555 is an acidic, foam-free cleaner used for deposits including limescale and prophy-powder residue. It does not replace disinfection. How frequently a system needs intensive cleaning depends on its use and the applicable product and equipment instructions.
Build a practical routine
Keep the current instructions where staff prepare the solution. Record the product, dilution, contact time and responsible team member in the practice protocol. Follow the required water-rinsing steps and keep cleaning and disinfection applications separate. Never mix the concentrates. Use the specified protective equipment and review the safety data before handling.
When cleaning is not enough
Reduced suction, persistent odours or repeated blockages should prompt an equipment check as well as a review of the cleaning routine. Follow the unit’s instructions for accessible filters and screens. Arrange professional service when a fault persists; adding more concentrate is not a substitute for finding a mechanical problem.
Which bottle should I order?
Choose Orotol Plus for the disinfection task and MD 555 Cleaner for intensive removal of deposits. Confirm compatibility with the suction unit before ordering. Both listings here contain one 2.5-litre bottle; they are sold separately, not as a combined kit.
