hi I'm J worked in the public schools for 31 years and during that time we were always looking for products that would help keep the or instruments clean maintained and ready for a rehearsal or the next concert and we've got some great ones here from Elkhart Indiana the faqs super select first lesson lines and they're great for maintaining your instruments for both performances and rehearsals brass players valve brass players want to introduce you to a product that super slick has developed and it's the t2 it's one of the very innovative new synthetic oils that is very smooth and long-lasting and won't build up beginning brass players have so many problems with their valves and the biggest cause is that they'll get them mixed up they'll get them reversed just a real quick tip one of the things and it's a great product that you can probably just pick up at any place and this is just a yoga mat and it'll keep things from rolling away one of the things that is a danger and I'm going to use this t2 which is a synthetic oil won't build up and is that you only pull and Porsche a part way out and let the oil run down on the valve guides don't do them multiple do one at a time and then carefully and you'll feel where it goes back in and just safely screw on this valve cap all the way don't try to do all of the valves at once where where students get into real problems is that they mix them up take your time don't take the valve all the way out because once it's here that's when younger players drop them and if you'll just let it come out and then graduate couple drops back down and you can notice that the valve guide in this case is on the top if you get them spun around you're going to go to your teacher and say my horn doesn't work and it'll take only a second or two but that's valuable teaching time now I'm going to do valve number three this goes a long way so this this one bottle will last you years unless you happen to spill it but you can just again down gently turn the valve put it back in and you'll save yourself hundreds of dollars in repairs just by doing that simple trick of how you're gonna oil your valves by not taking them all the way out but one at a time and carefully let the oil roll down you
