A question on cleaning beddings for Airbnb

[Leon Lee]

Hi, STR investors

I have a question on cleaning bedding sets and would appreciate your inputs:

Currently, I have bedding sheets set like this: mattress protector, fitted bedding sheet, flat bedding sheet and a comforter on top of it. We also have a fleece blanket for each bed. Because comforters can be bulky, it is almost impossible to wash all comforters for a house with 4 bedrooms within a couple of hours each time. So, what we did is to wash only bedding sheets and pillow cases for each batch of new guests, and only wash comforters and blankets when necessary. We used to use duvet covers to protect comforters, but our cleaning team complained that it takes forever to put the duvet covers back on. So, my questions are: 

(1) Is it acceptable to wash comforters and blankets only when necessary?

(2) What are your solutions?

Thanks in advance!
