How to protect bisque fabric on side doors??

I went through that when I had a 2011 Prius. If you have work done at Discount Tire or a similar place this is what I did because they will get it dirty. I cut a good size piece of plastic and fitted it over the door handle and used scotch tape to tape it to the non fabric area, near the window etc. before going to the garage. I did not spray mine with Scotchguard but that is certainly a good idea. If you use my idea with the plastic cover before going to a garage be sure to cover the armrest area because that is particularly the area that a worker with dirty hands will get it dirty. I also cover the driver's seat with a large beach towel. I have had dirty workers to get my seat dirty as well. We all hate that kind of inconsideration.
