How to Clean a Hood or Range Hood
It’s important to follow the right cleaning process to prevent fires and remove harmful airborne particles. This step-by-step guide will help maintain your system and protect your investment.
How to Deep Clean a Hood
- Turn Off Power and Prepare
Before you begin, switch off the power to your hood. This small step keeps you safe. Cover nearby surfaces to avoid splashes, and wear gloves to protect your hands.
- Remove All Filters First
Your hood filters are grease magnets. Slide them out carefully and set them aside. By removing them first, you give yourself better access to hidden buildup inside the hood.
- Clean the Hood Surface
Now, focus on the hood itself. Spray a degreaser across the surface and wipe with a microfiber cloth. Work slowly, paying attention to edges where you often miss hidden grease.
- Wash Filters Thoroughly
Place your filters in hot, soapy water or a degreasing mix. Let them soak, then scrub gently with a brush. Next, you need to rinse them until they look clean and you see no residue.
- Dry Everything Completely
Don’t rush this part. Dry your filters and hood thoroughly with a clean towel, or let them air-dry. When you reinstall, everything should feel fresh, dry, and safe to use.
