Abstract
A method of cleaning a lubrication system of a machine includes removing existing lubricant and circulating a cleaning fluid through the lubrication system. After the cleaning fluid has been removed, a neutralising fluid is circulated through the lubrication system, whereby the neutralising fluid combines or reacts with the cleaning fluid to produce a fluid that does not adversely affect the lubricating qualities of fresh lubricating fluid. An apparatus () for carrying out the method includes first () and second () reservoirs to receive the cleaning fluid and neutralising fluid respectively, one or more connectors to connect the apparatus to the machine, one or more pumps adapted to circulate cleaning fluid and neutralising fluid and a controller to control the transfer of the cleaning fluid and neutralising fluid from the reservoirs to the machine.
