I wiped down my seats today with Meguiar's leather wipes. The leather looks great except the driver's seat cushion...it looks like it didn't do anything to it. What could cause this? It's been really humid up here today...could that do it?
Since the driver's seat usually suffers the most use it may need a second or third treatment before your results equal the other areas of your interior.
I agree. Sounds like the leather absorbed the conditioner. If you have some, you might want to try adding a little conditioner from a bottle to a wipe to make it wetter, and trying again.
