My husband and I went to wash our dirty car after a road trip to Montreal. We were one of the first one there , there wasn't anyone there to give us direction on how to use it since it was our first time . also it was confusion there was a sign in front of us that said $2 and another that said $3 so we decides to put $3 in the machine which only takes coins , then chose high pressure water it took a minute to work , then it lasted for about 2 minutes then we put $3 to use the soap with the brush . I have to say that the place is run down and the equipment are old but the water pressure was good . The problem we realized is that u need to bring ur own cloth to dry the car but luckily they had a vending machine where we purchased one for a dollar it wasnt great but it got the job done . We drove the car out into the main lot to use the vacuum and to dry it with the cloth . The process took us an hour and about $8 I didn't think it was worth the hassle and the mess although my husband lovedit . The end result is car is very clean and it was done the way we wanted .
