Of course you will use the Resolution Center and charge them! If you start deciding to eat the price of the property damage that is caused by your guests, you will burn out of this business very quickly. Besides, it will often turn itself around where the guest is very gracious and provides apologies with the compensation which allows you the opportunity to write them an even better, more sincere review that they will benefit from and be encouraged to "do the right thing" again in their travelling future.
I like grey towels and there is no bleach to be found in my listing space. I have it in my house rules that bleach is not allowed to be used on any of my textiles also : )
P.S. I had guests come and stay once when I had just purchased new, very nice sheets. Apparently, he takes pride in getting "ink" in every city he visits. What an awful surprise! They did pay for the damages and were quite embarrassed. Hopefully he has learned to travel with his own sheets...
