I have some Greased Lightning Orange Blast citrus degreaser, and I was wondering if it's safe to use on tires? The bottle says it can be used full-strength on tires, but my concern is that it would dry out the tires, and cause premature cracking. I tried it on the tires on my Accord, and they turned really brown and discolored (wouldn't rinse off), but after I followed up by washing them with Meg's GC soap like usual, they looked fine again. Any thoughts on whether or not this is okay on my tires?
