Asthma, acute
"Just started using this one particularly, but every brand of MDI has similar issues people are complaining of here. I saw lots of reviews about it clogging and being useless. Just thought I&#039;d recommend what I&#039;ve learned to others to fix this problem. If you put warm/hot water in a cup and let it soak for a few seconds.. (I&#039;ll even shake it around in the water to help clean it) then dry it on a window sill or somewhere warm. You&#039;ll find that it will unclog the dispenser and is good as new  (as long as it is dry before you use it again). Happy breathing. Xoxo."
