I would NEVER do this, but...
With the microfiber like behavior of faux fur, and its ability to absorb a lot of water....
Use a fursuit to wash a car! I can see it now! A whole double row of furies all soaped up running towards your car. Then they start rubbing up against the car, cleaning it, with the suit they are wearing...
Personally I like Honey Sage Oat double conditioning dog shampoo, if you want to know. leaves a nice long lasting scent.
(FYI: Tails can get into tight spaces like a thin brush, good for cleaning those tires and rims.)
Wow....
