Clean & Flush™

Royal Purple’s Clean & Flush is a safe, effective and inexpensive product for cleaning sludge and varnish from equipment while in service. Clean & Flush can be used in three ways: First, Clean & Flush can be added to an existing oil to clean-up soft deposits and sludge from equipment prior to draining the existing oil. Second, Clean & Flush can be used as a temporary oil fill to clean varnish, soft deposits, and sludge from equipment before refilling with new Royal Purple oil. And third, Clean & Flush can be used as a temporary oil fill for cleaning and flushing a polyglycol oil that is incompatible with the new oil to be used (i.e., when changing from a polyglycol oil to any other fluid).

Clean & Flush may be used as a temporary replacement oil for cleaning equipment. When adding Clean & Flush to an existing oil to clean sludge and varnish, Royal Purple recommends a treat rate of 15 to 25 percent. Because Clean & Flush is available in only one viscosity grade and is not a fully formulated oil, machine loads, and oil viscosity USAGE GUIDELINES requirements should be considered when deciding how best to use Clean & Flush. Cleaning time and effectiveness will vary depending upon such factors as the cleanliness of the system, the oil temperature, degree of oil agitation, the amount of Clean & Flush added to the system and the duration of cleaning.

Flushing / cleaning procedures can vary depending on the type of equipment, the number and location of oil drain points, how dirty the system is, the quality of filtration and the ability to monitor and / or change filters / screens in circulating systems and other service parameters. Clean & Flush has some anti-wear properties, but it is not a full formulated oil. It can be used as a lubricant to clean and flush equipment in service for short periods of time. Whenever possible, it is recommended that Clean & Flush be circulated throughout the oil system while the equipment is unloaded or under low load, or idle. General guidelines for system flushing / cleaning follow.
