I am remodeling a new house and during the process, purchased a couple couches on sale from dwr. They were moved under the patio cover when the floor was being done. They were out there for quite awhile as the floor had to be redone. They were covered with sheets and did not get wet. Unfortunately, the sheets would blow off. I live in AZ and the dust is everywhere and when it's windy, it is really bad. I dont know the best way to clean these. Should I just vacuum them?

Thank you for any help.
