It is a shame that my first post on TMP has to be a negative one. The experienced players of brass instruments on the forum may not touch budget-priced care kits such as this in the first place; however, there might be beginners other than me on the forum so I do think that it is worth an airing. This kit consists of small bottles of slide grease and vale oil, and a variety of brushes. The slide grease seems fine. However, the valve oil reeks of kerosene or something equally objectionable. The Blue Juice that I have now purchased seems odourless. The main problem is with the snake-brush "designed" for cleaning around bends. I soon found out that this is worse than useless, and at one point wondered if it would cost me the cornet. What I had assumed would be a continuous "snake" of intertwined wire strands turned out to be stubs at either end, which contain the brush hairs, are pushed into a flexible hollow plastic tube and held in by friction. When I gave my newly-acquired second-hand cornet a deep clean today, I ended up spending an hour and a half extracting a brush head that inevitably came off, quite deep inside the cornet. I expect that this has produced some scratches to the inner surfaces of the tubing.
