How do i deoderise my dryer?

Question:all my clothes have this awful gym sock smell to them after being in the dryer. I have found the towels to be the worst affected as once they get wet they really smell like they have not been washed at all pls help.

Answers:
Make a solution of 50% water and 50% white vinegar. Use a sponge or towel to wipe out the inside of the dryer. Vinegar is a great, inexpensive deodorizer. The vinegar smell dissipates when it is dry.
