I go to Danny's on Bell rd. & 3rd ave a about 3 or 4 times a month for a car wash.
I have always been treated well and with respect. They used to really push the up sale hard but lately not so much. Which is a pleasant change.
They usually do a good job on exterior cleaning. Interior cleaning can be hit or miss. Sometimes fantastic, Other times not so great. If I'm not satisfied I ask that it be cleaned properly before I drive away. There is never a problem with that. They seem to want you to leave satisfied with the work.
Also quality seems to depend on how busy they are and/or staffing levels. Try to go at off peak times and avoid weekends.
Additionally the mornings seem better before employes are worn out at days end.
For an assembly line car wash Danny's is well above average. Like most things there is room for improvement.
They also provide many other services including oil change and detailing. I have no experience with anything other than the actual car washing.
