@Adrienne174 That's sort of opening a whole box of worms and indicating that you are willing to cater to all manner of personal preferences and allergies, some of them real and some imagined.
There isn't anything wrong with putting a line in your listing saying "Please let us know if you have any particular allergies and while we can't promise to be able to accommodate everything, we are willing to do our best."
If guests have serious allergies, it's really their responsibility to look after their own health and ask questions before booking.
As far as your laundry routine, and other scents, it's really advisable to stay away from heavily scented products and try to use more neutral products. An Airbnb should be as scentless as possible. I have no allergies myself, but no way can I sleep in bedding with a strong scent of the detergent, fabric softener, or dryer sheets. They just smell disgustingly chemical to me.
I use regular laundry detergent myself, but I line dry everything, so after a day in the sun and the breeze, they just smell like fresh air.
