About these prices

The cheapest unlimited monthly plan we found in Wentzville is at FastLane Car Wash - New Melle on 4659 State Hwy Z, at $20 a month. The cheapest single wash is at Scrubbles Car Wash, from $5. A typical unlimited plan costs about the same as 3 single washes, so it pays off if you wash more often than that each month.
