How should I clean and store my wood stove or fireplace for the summer?

Remove ash after 48 hours into a metal bucket with a tight lid, store it outdoors for a week, then dispose. Vacuum the firebox and glass (use a fine-filter shop vac or ash vac; avoid abrasive pads on glass). Inspect firebrick, door gasket, and flue—schedule a pro sweep if creosote is over 1/8 inch. Close the damper, store catalytic combustor in a dry bag, and leave the door slightly ajar to prevent moisture.
