It's probably a good idea to run new clothing through the dryer at a moderately high heat just in case any bugs - like bedbugs - hitch hiked into the store with a customer and took a ride to a new home (yours) on your newly purchased clothing. My dryer is right next to the garage, so I can conveniently do that before the clothes gets in the house.
Anything fabric item frome the thrift store is washed and dried before it gets into the house.I don't know where it was before the thrift store and so many of the items are "scented" (a) via the 'air fresheners" that can be bought through any store and placed in an electric outlet in your home, (b) colognes used by the former owner. I am particularly sensitive to fragrances; not allergic according to my Dr, just 'sensitive'.
The air fresheners creep me out - breathing all those fragrant chemicals all day long doesn't seem like it would be good for me.
