Waxy flanges

Hello All.
A new customer of mine has a 1913 Steinway Vertigrand upon which a well meaning technician has sprayed the action flanges with an apparent wax based lubricant. It obviously worked to bind up the action rather than lubricate it and has left a waxy film on the flanges. Do any of you know of a solution I can apply to disolve it and free up the action? Any suggestion are appreciated.

There is a time when half measures just won't work. It's very unlikely that anything short of replacing the flanges is going to be satisfactory. This is a Steinway after all.
The previous tech tried to get away with a quick fix and ended up making the problem much worse. You didn't cause the problem so it's not your fault that it is going to be expensive to repair.
The flange bushing felt was already clogged with vertigri and then it was impregnated with something waxy to boot. Putting a solvent on it may free it up a bit but where is the wax going to go? Usually when you wash something you have to rinse it.
Years ago I tried repinning complete sets of flanges in a number of older pianos that had loose center pins. It worked really well at the time but when I came back a year later to tune these pianos, I found that the center pins were starting to loosen again. I came to the conclusion that the old felt had lost its’ resilience. That resilience is what gives the combination of friction and give that is present in a new tight action center. You can bet that this gummed up felt has lost its' resilience big time.
This is one of those times when you need to take charge and tell it like it is.

Wax is dissolved by mineral spirts or paint thinner. I had some damper wires someone had used Johnsons paste wax on. I took a pipe cleaner and thinner and the bushings worked and looked fine afterwards. Just lucky I guess.

Thank you both for the replies. I'll try the thinner and if it doesn't work I'll recommend she upgrade or sell to a rebuilder, PTG chapter or one of the traveling wholesalers.

Take the action outside and flush it out with VM&P naphtha (very flammable, don't do this indoors! Messy too.) This is cheap enough to be worth trying. Try it twice, even.

If the solvent is only partially successful, you may be able to remove a small amount of felt on the bushings with your reamer, to get new-ish bushing felt, then re-pin.
But by that time, you may as well rebush...
