Dry cleaning should be used very sparingly. What matters much more is how you care for your suit at home. Following the simple maxims below will extend the lifetime of your suit—and save you many trips to the cleaners.
Give it a brush. Use a soft bristle garment brush to gently remove dirt, dust and food particles after every wear. Start at the shoulders and slowly and softly brush downward, taking care to ensure that the brush is parallel—not perpendicular—to the jacket. Not only does this method keep the jacket clean, but brushing away food particles will also make it less likely to draw moths.
Hang properly. In order to preserve the drape of a suit jacket, you’ll want to hang it from a substantial wooden hanger or a plastic hanger with rounded edges. In the closet, leave an inch between each jacket to prevent its lapels from being crushed and wrinkled.
