Varnish mitigation process

A method of flushing a hydraulic system including a fluid circuit and an in-service fluid flowing therein includes fluidly coupling a kidney loop to the fluid circuit such that at least a portion of the in-service fluid may flow therethrough, the kidney loop including a depth media filter and a micro-glass filter arranged in a parallel flow pattern and introducing a solvent cleaner into the in-service fluid at a concentration level between approximately 2.5% and approximately 6%, the solvent cleaner including at least one hydrocarbon group V fluid. The method further includes maintaining a temperature of the in-service fluid between approximately 100 degrees Fahrenheit and approximately 155 degrees Fahrenheit and controlling the flow of the in-service fluid at a flow rate between approximately 3 gallons per minute and approximately 6.8 gallons per minute.
