A shiny, efficient range hood is the crown jewel of a modern kitchen. However, it is also the hardest working appliance, silently trapping grease, smoke, and odors day after day. Over time, that sleek stainless steel surface can become sticky, and the motor can struggle under the weight of accumulated grime.
Neglecting your range hood doesn't just look bad—it's a safety hazard. Grease buildup is a leading cause of kitchen fires and can significantly shorten the lifespan of your appliance.
In this comprehensive, step-by-step guide, we will teach you how to deep clean every part of your hood—from the exterior casing to the internal fan blades—restoring it to showroom condition.
The right tools make the job half as hard.
Phase 1: Preparation & Safety First
Before scrubbing, you need to prepare the area. Cleaning a range hood can get messy.
What You Will Need:
- Degreaser: A specialized kitchen degreaser or a DIY mix of warm water and dish soap.
- Baking Soda & Vinegar: For tough stains.
- Microfiber Cloths: Essential for stainless steel to prevent scratches.
- Soft Bristle Brush: An old toothbrush works perfectly for corners.
- Plastic Drop Cloth: To cover your stove top.
⚠️ Safety Warning: Always lock the control panel or unplug the unit/turn off the breaker before cleaning the interior to prevent the fan from accidentally turning on.
Phase 2: Cleaning the Exterior (Stainless Steel Care)
Most Brano Range Hoods feature premium stainless steel. Cleaning it incorrectly can leave permanent scratches.
1. Identify the Grain
Look closely at the steel. You will see faint lines running either horizontally or vertically. Always wipe in the direction of the grain. Wiping against it forces dirt into the tiny grooves and creates scratches.
2. Apply the Cleaner
Spray your degreaser onto a microfiber cloth (not directly on the controls to avoid electrical shorts). Wipe the exterior surfaces gently. For sticky dust on the top of the chimney, let the degreaser sit for 5 minutes to break down the bond.
3. The Polish Finish
Once the grease is gone, use a dedicated stainless steel polish or a drop of olive oil on a dry cloth to buff the surface. This restores the shine and creates a protective layer against fingerprints.

Phase 3: Addressing the Filters
The filters are your hood's first line of defense. If they are clogged, the motor has to work twice as hard, which creates noise and reduces suction power.
Whether you have Aluminum Mesh filters or Baffle filters, they need deep soaking. We have written a dedicated, detailed tutorial on this specific component.

Phase 4: Cleaning the Interior & Fan Blades
This is the part most homeowners ignore, but it is crucial for E-E-A-T (Expertise, Experience, Authoritativeness, and Trustworthiness) maintenance standards. Grease eventually makes its way past the filters and settles inside the housing.
1. Access the Interior
Remove the filters. Use a flashlight to inspect the motor housing and fan blades. You will likely see a thick layer of sticky, brown residue.
2. The Steam Method (Chemical-Free)
If you have a handheld steam cleaner, this is the easiest way. Blast steam into the crevices to melt the grease, wiping it away immediately with a cloth.
3. The Spray & Scrape Method
If you don't have a steamer, spray a heavy-duty degreaser onto a paper towel (do not spray up into the motor directly). Wipe the interior walls. For hardened grease, use a plastic scraper (like a credit card) to gently lift the gunk without scratching the metal.
Note: Be extremely gentle with the fan blades. Bending a blade by even a millimeter can throw the fan off-balance, causing loud vibrations later.
Phase 5: Troubleshooting Odors & Noise
Sometimes, a clean hood still smells bad. Here is the expert checklist:
- Check the Damper: Ensure the backdraft damper isn't stuck shut with grease.
- Inspect the Duct: If you use a ducted range hood, grease might have accumulated in the ductwork. This requires professional duct cleaning.
- Replace Charcoal Filters: If you have a ductless/recirculating system, you cannot clean charcoal filters. They must be replaced every 3-6 months.
Is Your Hood Beyond Saving?
If your range hood is over 10 years old, the motor is rattling despite cleaning, or the buttons are failing, cleaning might only be a temporary fix. Modern hoods are significantly quieter and more energy-efficient.

Frequently Asked Questions About Cleaning
1. How often should I clean my range hood?
For best performance, wipe down the exterior weekly. Clean filters every 1 to 3 months depending on cooking frequency. A deep internal clean should happen once a year.
2. Can I put my range hood filters in the dishwasher?
Most stainless steel baffle filters and aluminum mesh filters are dishwasher safe. However, check your manual. Aluminum filters may discolor (turn grey) in the dishwasher due to detergent chemistry, though they will still function.
3. Can I clean charcoal (carbon) filters?
No. Charcoal filters used in ductless hoods cannot be cleaned. They are designed to trap odors in their pores. Once saturated, they must be replaced, typically every 4-6 months.
4. What is the best homemade cleaner for sticky grease?
A paste made of baking soda and a little vegetable oil is surprisingly effective. The oil helps re-liquefy the old, hardened grease, and the baking soda acts as a mild abrasive to scrub it away.
5. Why is my range hood still dripping grease after cleaning?
This often means grease has accumulated in the motor housing or the ductwork above the hood. You may need to disassemble the motor cover to clean inside, or call a professional duct cleaner.
6. How do I clean the fan blades safely?
Use a damp cloth with degreaser. Do not remove the blades unless necessary, as they are precision-balanced. Do not spray liquid directly onto them, as runoff can damage the motor bearing.
7. What kind of cloth should I use on stainless steel?
Always use a clean microfiber cloth. Paper towels or rough sponges can leave micro-scratches that make the surface look dull over time.
8. How do I remove white haze or streaks after cleaning?
White haze is often caused by leftover soap residue or hard water minerals. Wipe the surface again with distilled white vinegar, then buff dry with a drop of olive oil or stainless steel polish.
9. Is it safe to use bleach on my range hood?
No. Bleach can corrode and pit stainless steel. Stick to dish soap, vinegar, or dedicated stainless steel cleaners.
10. Why is my hood making a rattling noise after cleaning?
You may have accidentally bent a fan blade, causing it to wobble, or a filter might not be seated correctly in its latch. Check that all parts are secure.
