1. The guitar bag can be used to remove dirt from the concealed area and the gap with a toothbrush that is not used, or you can use a "nylon shoe brush".
2, after the guitar bag brushed off the dust, for stubborn stains, first rinse with water, then brush off, and then spray with the care solution. (Try to avoid contact with metal fasteners during brushing to prevent rust.)
3, after the guitar bag cleaning, it is best to dry outside the house, be sure to avoid direct sunlight exposure.
4. Do not place the wet guitar bag near a heat source such as a fire or heater. Otherwise it will destroy the fabric structure, not as strong as before.
If the guitar bag is not going to be used for a long time, it should be placed in a ventilated, cool place to avoid sun exposure, but the environment in which the guitar bag is placed should not be too humid, otherwise it will make it moldy and become more difficult to handle.
