Why
Standard disposable Solo cups are made of thin polystyrene or polypropylene, which can warp, melt, or become misshapen in the high heat of a dishwasher. Even reusable versions may have printed designs that fade or peel. Most manufacturers advise hand washing to maintain appearance and structural integrity.
How do you wash Plastic Solo Cup?
Hand wash with mild soap and warm water, then air dry or dry with a soft cloth. Avoid abrasive scrubbers to prevent scratching.
