The delicate cycle would be for clothing that should really be washed by hand so that it will not get ruined, snagged, etc. Example, a ladies bra that has underwire would normally be washed by hand; but it can go in the gentle cycle for washing and it should really be hung up to air dry and not go in the dryer so it will keep it shape and not mess up so quickly. So clothing that you want to make sure it keeps it shape and not be damaged should go into the gentle cycle. This includes thin cotton clothing, pantyhose, nylons. Also, nice dress shirts or blouses work well in the gentle cycle. Get the idea? Hope so. If you want to know more go to Tide.com.
