Josh, it seems you were also asking about price, and not how to clean things.
The material cost and needed time to create as safe an environment as possible when dry cleaning should factor into your price.
However, I've never been comfortable with the following scenario:
"Wet Clean costs less money and cleans great"
"Dry Clean costs more money and doesn't clean"
First, the two terms stink. Few people want to think of things being "wet", and dry cleaning isn't "dry"....its oily and often feels that way longer than something you "wet" clean.
Instead, look at it this way:
To safely use water based products (hate "wet cleaning" as a term) it requires:
1. Knowledge and Experience
2. More expensive cleaning agents and dye stabilizers
3. More time to do the job safely.
4. More time to do finishing work, such as texture restoration
Therefore, even if you aren't using 20.00 + per gallon dry cleaning fluid, you are spending more time and taking more steps.
So you might have a "Special Care" price that covers any high value/high risk cleaning procedure, and a "Standard Care" price that covers the safe and easy synthetic fiber fabrics.
The other thought might be to simplify things and have one premium price that covers all cleaning you do, because your customer pays for you to know what to do and what products, tools, and procedures best suit their needs.
That's a marketing and management decision rather than a production cost decision, of course.
