Cooker hood grease filters should be cleaned at least every two months, or more often with frequent use or frying. Some AGA models signal cleaning after around 30 hours of use. To clean metal filters, remove them carefully, soak in hot water with washing-up liquid for at least 10 minutes, then gently scrub with a soft brush. Rinse thoroughly and allow to dry completely before reinstalling. Alternatively, place filters in the dishwasher at 65°C (alone) and dry after.
Avoid abrasive tools or harsh chemicals. To reduce build-up, wipe filters regularly once cool and consider using a splatter guard. Charcoal filters cannot be cleaned and should be replaced every four months. Regular cleaning improves performance and prevents heavy grease accumulation.
