Just went to this Washman today and super impressed! The gentleman working was so nice and professional and took great care to help clean our super dirty car from our road trip. If the manager reads this, please let him know he’s awesome!

I brought two extremely dirty cars into this location and was so impressed with the quality of clean. The person who washed them did an incredible job, spending extra time hand washing the dirt and tree sap off. It was just an extra $3 "extra soil" fee on top of the cost of the wash. He even did a second hand wash round, free of charge. The cars turned out just about as well as spending a ton of money at a professional detail shop, but way cheaper here! This is definitely my new go-to spot to wash my cars.
