The stuff the cleaners use trigger an attack. If I'm walking past them, I can hold my breath but if they come into our area to start cleaning desks or windows, there's nothing I can do except move away (if I spot them before they start).
Also eveyone in my team knows Flash wipes badly affect me (they are citrus) and my manager got one out on Friay. I moved away as soon as I smelt it but it was too late and I had to take my inhaler 4 times before my breathing improved. I'm taking in some wipes I know are OK but I wasn't at my best on Friday (I was supposed to go and visit - and talk to - several people but only managed the most urgent and that was late) or on Wednesday when a cleaner arrived and started spraying the windows.
