LS460 interior
 

I have an 2007 LS460L and the last couple of years the dash material has been acting/reacting strangely to heat. The texture on the black “soft touch” panels develop a shinny, sticky coating on them once they get hot (primarily a summertime issue in TX). I’ve tried several cleaning techniques and products to no avail. Has anyone heard or seen this before? Any resolutions? TIA
