I have MCS/MCAS so I too need a non toxic environment. I contacted one place...non airbnb...a cabin in the mountains. She worked with me. She only used vinegar to clean and do the laundry. 5 min into the place and I had to leave. Even walking in I was hit. But, I needed to rest before i got back on the road. I could not rest. It seems if the place has had fabreeze and other toxic chemicals used for years, there is a built up. It was in the walls, furniture etc. A costly experience for me. Since i rented it for a week and there was no refund. I paid ahead of time.
I am still looking for places to stay that will not make my health worse. I had no idea there were so many products on the market that use toxic chemicals. Products I had used all my life until health went south.
Products that are known to cause health issues. I thought since it was on the market it must be fine. Wrong.
