Start by disconnecting or powering off the device associated with the vent plug, if possible. This prevents accidental damage to the device during cleaning and ensures safety.

Use the soft-bristled brush to gently sweep away loose dust from the plug's surface. Move the brush in light, circular motions, focusing on crevices or textured areas where dust tends to accumulate. Take care not to apply too much pressure, as this could push dust into the plug's micropores or deform its structure.

For slightly sticky or stubborn dust that remains after brushing, dampen the lint-free cloth with a tiny amount of distilled water. Wring out excess water thoroughly so the cloth is only slightly damp—moisture should not seep into the plug's interior, as this could compromise its waterproofing or damage the breathable membrane. Gently wipe the plug's surface with the damp cloth, following the direction of any visible texture to avoid spreading dust or leaving lint behind.

After cleaning, allow the vent plug to air-dry completely in a cool, well-ventilated area before reusing or reattaching it to the device. Do not use heat sources like hair dryers to speed up drying, as high temperatures can degrade the plug's materials. Once dry, inspect the plug's surface to ensure all dust is removed and check that its structure remains intact.
