Shut down the vents and break out a little tile cleaner that we just so happen to use in the bathroom.....nothing fancy....give her a lit shine once in a while....speaking of your red dirt..... I love red dirt, gritty country music....shames those twangy Nashville folks.... I spend a lot of my time in Austin and fell in love with the whole outlaw music scent - REK, Gary P, McMurtry, Ray Wylie, JJW, good stuff if it appeals to you... Sent from my iPad using Tapatalk
