Lifting dark stains out of finished wood with an oxalic-acid cleanser paste instead of refinishing.

Restoring airflow to a bath fan clogged with dust and grime.

Clearing the filter and spray arms so a dishwasher works properly again.

Cleaning up spilled screws and nails fast with a bagged magnet.

Keeping fine dust out of the pleats so filters last.
