I'm very lucky in that I work 2 minutes from my barn (about a 20 minute drive from home). I see my horses before and after work every day. I keep a duffle bag of spare barn clothes, and a bag of "work clothes" in my car, and I keep multiple pairs of boots and shoes in my trunk in plastic shopping bags. That way I always have smelly "barn clothes/boots" and clean stuff to swap into if I get slobbered on. The biggest thing is the boots/shoes. I also keep baby wipes and body spray in my car to clean up with.
