Update: I found out about a promotion that if you sign up to a Circle K account, you can get free car wash 1/day for 3 months. Not sure if you can go with your different cars but very neat. So take advantage of that for the winter.
I've been meaning to get a car wash for a while, and Circle K has an amazing deal... $50 for four premium washes, normally $20 each. Be sure to grab the car wash booklet early! I once asked for it, and they only had 8-10 that day. They sold out by the evening and restocked the next day.
The lineup is long around 2 pm on Sundays, with 8-9 cars waiting. A gas station attendant mentioned that nighttime is a better bet for shorter lines.
Don't forget to scan your Optimum card at checkout to collect points. The car wash takes no longer than five minutes, making it a quick way to clean your car and protect the paint in winter --until it's warm enough to wash and detail it yourself. read more
