I was recently fortunate to get involved with a major manufacturer of chemicals. For the first time in a long time I can aggressively go to washes, see what they have, and sell something superior. It's made me look closely at all self serve locations. What I've noticed kind of surprised me. I would guess that only about 20% of then really have a decent product that is adjusted properly. It's no wonder that driveway washing is still the major competitor. To those of you here reading this, don't take offense this. Most of the forum regulars would fall into the 20% doing it right. It's just been kind of eye opening.
