Overview
Fat Cat
Fat Cat Valve Oil
Fat Cat Valve Oil is ultra-refined petroleum oil that chemical tests have shown to have fewer impurities than other popular valve oils. Fat Cat's viscosity ("thinness or thickness") is similar to other "fast" oils but works better because of its purity. So much so that it OSHA considers Fat Cat Oil as non-toxic, non-carcinogenic, non flammable and non hazardous. Be assured that Fat Cat Oil will work extremely well in trumpets, baritones, euphoniums, French horns and tubas of all makes and ages. Its precision applicator tip makes it especially easy to reach rotary valve bearings.Application
When trying Fat Cat Oil for the first time, clean off all old oil with soft cloth. It might be a good idea to give your horn a bath at this time, although it is not absolutely necessary. Mild dish detergent (Dawn "Power Plus" is great for this) run though the slides and valves (remove pistons before washing) will wash out old oil and sludge. For piston valves, coat both the valves and valve casing before reassembling. Rotary valve instruments will lubricate both the inner and outer valve bearings. A good squirt of Fat Cat Oil into the first tuning slide, which is then inserted all the way in (to avoid the grease of the slide), followed by a few rotations of the horn, will allow the oil to reach all the rotors. Next, wipe your tuning slides clean with a soft rag (if the old slide grease won't wipe off, use a little paint thinner on a cloth). Apply a thin coat of Fat Cat Tuning Slide Grease on the valve slide. If you get excess grease squeezing out of the tuning slide tube, you put on too much. Wipe excess and wash hands after use
