In the art of sailing vessels, various styled tracks retain an edge of a sail. A retained sail edge is prone to fouling by environmental conditions and becomes exceptionally difficult to remove. A disclosed Foiling Rabbit 100 or track conditioner, cleans, lubricates and otherwise services the sail void area of a track or other sail retention area. A cleaning wick 400 may have main body 430 attached to a thickened or rolled interior edge and outer surface 430. An inner edge of the wick may be retained within a wick retaining cartridge 7. A lubricant cartridge 1 may be attached to the wick retaining cartridge. The lubricant cartridge may define one or more reservoir bodies 2a which may contain a lubricant and cleaning fluid. By use of various direct and indirect channels, and controlled capillary action, lubricant flows from the lubricant cartridge to a workpiece removes debris and lubricates.

A method comprising providing a first fluid, second fluid, and third fluid having a first kinematic viscosity and a first BN, a second kinematic viscosity and a second BN, and a third kinematic viscosity and a third BN respectively, obtaining data identifying (i) a target kinematic viscosity of a cylinder oil to be produced, (ii) a target BN of the cylinder oil to be produced, and (iii) the kinematic viscosity and the BN of each of the first, second, and third fluids. Based on at least the identified kinematic viscosity and BN, the method comprises determining a ratio of first, second, and third fluid to produce a cylinder oil having a kinematic viscosity corresponding to the target kinematic viscosity and/or a BN corresponding to the target BN, and blending the first, second, and third fluids in the determined ratio to produce the cylinder oil.
