I did a quick search for "lint" on Google and didn't see much interesting but on the third page found info from Snopes regarding lint. Yes, Snopes, the Web site subtitled "Rumor Has It." Snopes verifies or nullifies gossip, emails, and the like.
The Snopes lint entry is regarding the claim of lint filters on clothes dryers getting clogged when you use dryer sheets. Turns out, it's true. Dryer sheets can clog the mesh screens on dryers with a film that causes the heating element on the dryer to overheat and go out.
I personally don't use dryer sheets, so I guess my dryer's good to go. Do you use dryer sheets?
