Hi,
I would not recommend it. The potential to create a problem is too great. At 94k mi., the wiring is likely to be brittle from Heat Cycling, or you could cause internal damage in trying to remove them - you could actually cause a malfunction.
I'd recommend leaving them alone until you get the CEL and then try cleaning them, worse case, you have to replace them, but not prematurely. Hope this helps...
Happy Motoring!... Jim'99
