Well so far we have various mixtures of 3in1 with other valve oils with Blue Juice being one the favorites mixer's. We have some that are useing BreakFree CLP. I have heard of Bag Balm,Vasoline,Chapstic,and Lanolin being used for slide grease. Let's hear some of the things that have been tried and failed or tried and worked well when you where in a pinch! I have conisdered trying various additives mixed with Crisco. So let's get some talk going. Does any one have some off application use's? I just emailed BreakFree's owners to tell them that some are useing their product for trumpet valves. I also asked them if their was anything inthe formula that might not play nicely with the alloys that Trumpets are made from. I recieve any warnings I will let you guys and gals know. I use breakfree when I first get a horn to soak everything down and gently break down the dried residues in the horn an don the valves etc...I have never left it on though or tried it as a lubricant. I was useing it as a cleaner prior to washing it inthe tub. Any products that you have not tried but you wouldlike to try as a valve oil or slide grease?
