I never used to have to valet them so frequently but my new housemate is Pigpen from Peanuts. Everything he touches even if he tries to verbs after himself gets ruined. What will carry out the tough stains without wearing the material threadbare after many launderings?
Answers:    Try Oxyclean. It really works. Otherwise, when he messed them up, spray them next to spray n wash next to oxy. Hey if it can get red cool aid that have set for weeks, it can clean anything. Gentle on fabric too.
put plastic wrap on mats previously mr piggy sits down, eats or anything else, and report to him to clean up his mess when done, that near is no free ride in the cleaning dept
