Interestingly when my tech chap called to service my concentrator he went through a check list with me which among the ususal of not cooking with 02, no smoking near etc also included not using - hair sprays, cleaning sprays, spray deodorants etc. Admottedly this is all for 02 users but it makes sense for the rest of us.
I have not used sprays for years now and insist my cleaners use wipes; not mixing cleaning liquids eg bleach and disinfectants. I also use a pump action hair spray Naked which has none of the breath catching smells to it at all.
Perhaps we should be lobbying the supermarkets for things like this to be placed in the "free-from" aisle??
