I haven''t used aerosols in my house for years because of my asthma. I was very sensitive to all the cleaning compounds at work, especially when the one cleaning lady added
BLEACH !! to her mop water. Holy cats! I'd go into an asthma attack as soon as she got in the room. Had to sic the bureaucrats on her to get that stopped.
Now, I use vinegar and baking soda to clean everything at home. No cleaners allowed.
Starch comes in spray or liquid. I just put the liquid in a spray bottle to use it and hold my breath.
As for spray baste - I don't use it. Never even looked at it.
