I am terribly allergic to some cleaning supplies. Others are okay. If you have ones you use at home that you can tolerate, ask if they can use that instead. I am guess she won't care what she gets to use, as long as it's something ...

I have always been this way. At my last office, they hired a new cleaning crew who came and used Tilex to clean everything, and I literally had to go outside for half an hour as I was ill, and dizzy and had an instant and massive headache. After that, we just bought 409 to have in our office, which I can tolerate, and they used that.

My sensitivities are so bad that I used to need an inhaler if I went to the supermarket when it was late and they were washing a floor in part of the store. Anything with ammonia in it is sure to get me. And when I was in college, and a certain Boston MBTA station smelled like urine, I had to hold my breath going in and out or I'd be wheezing up a storm by the time the train came.

At least I am not as sensitive as my sister, who cannot even use soap without a bad allergic reaction. She uses Lowilla or "Pear's Soap" which is actually glycerine, not soap.
