with a soft cloth. In case of heavy soiling, soak a cloth in
neutral detergent diluted with water, wring dry and wipe,
followed by wiping again using a dry cloth.
Pay attention to the following to prevent the cabinet from
deteriorating in condition, getting damaged, or the paint
from coming off.
● Do not wipe with a stiff cloth

using a vacuum cleaner. Wipe using a cloth if a vacuum
