I don't give 5 stars lightly, but this coin op accepts credit tap payment, only costs $3 and is high quality all-around. I drive a sports coupe so I wash my car every other day in the summer and re-ceramic and/or wax buff my car constantly. I spent an entire summer looking for the best coin op in Oakville, here's what I found-
3rd line and Speers is cheaper, but is also low quality, barn style. One or two of the bays is alright but only during sundown or you'll get water spots a good winter spot because who cares in December, but in the summer you'll wish you didn't. Might as well wait until you need to take a long pee and spray your car with urine. It's actually that bad, minus the smell.
Winston and royal Windsor is good, too. But is more expensive iirc and is too busy most of the time.
The other one across from Oakville GO is usually closed. Don't know what their issue is, don't care. They need to be open consistently or I'm not turning all over the place to check. Otherwise my 2nd favourite coin op.
A tip, don't go to any coin op when they're busiest. It'll be impossible to microfibre-dry your car in the shade and you will get water spots. Even if you use detail spray, and in some cases the spray makes it worse.
