Product review (5 stars): Ruined white t-shirts was the worst for me
Another part of what we needed to fix our dryer.  This part had worn off or something and was putting smears of something on our clothes, before we realized what was causing it.  Ruined white t-shirts was the worst for me.  But, thankfully, this is a do it yourself project, and my son fixed it for us (yay him!) and we now have heat and no more smears.
