Rust colored mark or short line on tee shirts

To all victims of the brownish colored streak marks: I share your frustration!!! I have the same problem with my dryer which started when my dryer was only 3 or 4 years old - - totally unacceptable for an expensive top of the line dryer! A repair guy showed me how the brownish streak marks come from the felt liner which goes around the drum. Look inside your dryer for the beige or tan colored felt which sticks out around the circular drum. If you rub the felt with an old white t-shirt or paper towel, you will see the same brownish colored marks. My repairman recommended getting the felt replaced eventually, but until then, he gave me the following tips which really help avoid getting the streaks: For white or light colored clothes susceptible to the brownish streak marks: I dry these items as part of a very lightweight dryer load - with just a few other lightweight items. By doing a small lightweight load, clothing is less likely to get caught up & rub against the felt edges. For example, I dry 4 light colored men's dress shirts with 2 or 3 other lightweight shirts. OR for white or light colored athletic "dry fit" type athletic apparel, I dry 6 - 8 total lightweight shirts/shorts. If I throw my white Nike top or white pair of summer pants into the dryer with all my "whites", they will be doomed to getting brownish streaks due to the heavy load pushing them against the darned felt liner! Whenever possible, I wash susceptible items on permanent press to avoid wrinkling, then hang dry. Prior to putting these clothes in the dryer, I also "pre-clean" the felt with an old white cotton t-shirt by reaching into the dryer and rubbing along the felt edges until I'm not getting as much brownish color on the t-shirt rag. For a permanent fix, call a repairman or see the following do-it-yourself YouTube video on "Dryer Repair - Replacing the Lower Front Drum Felt Seal": http://www.youtube.com/watch?v=XoYP_YsGP68 . I have a repair person coming today to fix 2 other appliances, so I'm finally getting my dryer fixed, and I will post an update soon.

Most likely coming from your washer....when clothes are wet it harder to see marks....washer needs new seals.
