Hello @Tami1
What a dreadful guest😱 In answer to your last question about house rules, I have included the following:
Permanent damage to towels/linens due to skin treatments or hair dye will be charged.
I lost 8 towels over a few months last summer due to teens using acne treatment and after querying a guest over the possible cause of the yellow stains on the towels, she admitted that it was due to her son's treatment and that she had the same problem at home. 😮 BUT, she did kindly offer to refund the amount for the replacement of the towels😊 yeah a sweetheart. Not so lucky with the second lot of guests with teens😡
Have you tried baking soda and vinegar for the bath and sink countertop?
Hair dye and skin treatments seem to be the #1 cause of ruined towels and some hosts will tell you that it's the cost of doing business but at least it's in my house manual and the guests are forewarned that a charge may be applied.
Hope the stains come out🤞
All the best
