Last week, I had just gotten off a long video conference call for work when my Wife comes down to my office. (It's in the basement) She asked if I had my cage on. A rhetorical question I assume as she has the keys. So I scoot back from my desk and bring my pants down so she can see. Not uncommon considering I very rarely leave the house these days. Now for the discovery, she, rather deviously, pours wax from a tea light I had burning onto the cage. The good news was, it wasn't very hot so even though I did flinch a little from the shock, there was no pain. The great discovery was that the wax/paraffin (I think) was a great lubricant, and made wearing the cage more comfortable. I was wearing an A231 at the time. I haven't tried this with a plastic cage but it works great with steel.
