If it is dry cleaning, choose a dry cleaner with oil. When using tetrachloroethylene for dry cleaning, there will be high temperature, which may dissolve beads, but oil will not. However, the oil stains on woolen clothes are quite difficult to deal with.

Also, the wool content of your clothes is not very high. If you wash it with water, wash it by hand, don't stir it in the washing machine, wash it with water yourself, and then dehydrate it in the washing machine for two to three minutes, it won't shrink.

As for the non-rotating cage turnover drying, this has no practical significance, so don't care too much.
