There's a lot of variance but I wouldn't be too preoccupied with them. It's like a hairstylist being concerned about the barber. People who regularly use Chem dry generally don't cross over and vice versa.
I only know what i hear from the others, its just like here, theres always someone who claims to be getting ridiculous prices and others working to cheap.
I know of a few that really get .75 a foot and deserve it. They are excellent cleaners that care.
Has nothing to do with the cd process, just happens to be great cleaners that got stuck with a cd franchise.
I will tell you that the rinse product for us is getting close to two dollars a gallon, and is basically water. With that in mind there has been a big push to get more for what we do, so they have pushed the zees tp try to up the game and go high end.
Some are doing that successfully. Others are holding on to the old. If you see ads for "legacy" cleaning from a cd thats the old bonnet system, usually a lower price point. It can be done very inexpensive.
