I already have Trombotine and use it to maintain my slide and tuning slide. I don't know, what to choose, but I've read a S.E. Shires Maintenance Guide, and there is written, that it's better to use Hetman Light Rotor Oil and Hetman Light Bearing and Linkage Oil.
Tell me, can I buy one of this oils and use it both for the Valve and Linkages? Because I want to save my budget, but if it will damage my instrument and my axial valve will have some troubles, I of course, buy both the oils.
And, maybe, there are some other variants of oil? Thanks
