I am allergic to chemicals which cause respiratory distress.
I use the 505 which has the least amount of odor. I place a big sheet of paper in the bathroom and turn on the fan.
Lay everything in position, hold my breath and spray. The fan takes it right out of the room. I always let the fan run for awhile after I'm finished spraying so it doesn't migrate into the rest of the house. I only do a little at a time. But atleast I have worked out a method that I can tolerate so I can do my machine embroidery.
