Wax Removal Help
As we've previously discussed, Renomat is oft recommended as a product capable of removing old, built up layers of wax. While waiting for Kirby's site to start carrying the full Saphir line, I picked up a bottle of Lexol's PH Balanced leather cleaner. My goal was to remove built up layers of dark brown Kiwi wax from a pair of walnut colored Allen Edmonds Westchester loafers.
The shoe was one of my early attempts at a mirror polish and I made two mistakes. I went too heavy on the wax and applied wax too far up on the vamp. We all know that too much wax (esp in this) area won't look great once the shoe starts to crease. Here's an image of the shoe in question after polishing and before wearing.

I started applying the lexol with a round horsehair dauber and working it into a lather. By the time I finish the 2nd shoe, I start wiping it off the first shoe with a damp cloth. The I repeat the process...and repeat...and repeat...and repeat. After I remove the wax, I'll condition with renovateur, apply a couple of coats of AE's walnut cream polish, then add a lighter brown wax just to the toe and in much smaller amounts than before.
I'm just wondering how to remove the old layers of wax without risk of damaging the leather underneath. Should I let the Lexol do the work or use more elbow grease? I can see the wax coming off onto my soft cloth so clearly it's working. But the low hanging fruit is the easy part. I'm now at a point where I can see the dark brown wax in certain spots but very little is transferred to the cloth when I wipe the lexol off. How much pressure is too much? Can I damage the leather with too much rubbing or too much product? Should I let the lexol sit for a period of time or work into a lather then wipe clean/remove the product immediately?
My initial goal was to achieve a mirror toe, like this:

By the time I polished the dark brown blucher above (AE Kenilworth) I knew not to apply too much wax and not to apply too much wax up the vamp.
Thanks for any help.
