I'm with Kalama. The inside of my dryer is stainless and very slick. The clothes are being tossed around constantly. I doubt any pet dander would stick to it. I do toss clothes that have been worn in to de hair or de wrinkle them, but it's not like they are all sweaty or icky and I do take showers on a daily basis so my clothes aren't all icky after being worn for a short period of time. A lot of the time, it will be a jacket that wasn't in contact with my skin at all so it doesn't bother me.
