There is no need to Dry Clean the upholstery in the TM it is easily cleaned with Hot Water Extraction.
1. remember the TM is a small area so consider using hypoallergenic products to clean to prevent allergy issues.
2. If you use a home machine make sure you rinse well with water only since most products used with hom units leave significant residues.
3. Never wash any part of upholstery in washing machine unless you don't care about color match since a washing machine will cause unnecessary color fade & some wear on fabric.
4.Dry Cleaning solvents don't just go away so I would never suggest sleeping on them this is just my opinion though.
We use this after every trip & we also protect all upholstery & curtains.
