The Surprising Power of Cola
Coca-Cola contains phosphoric acid and carbonic acid mild acids that can break down old grease and loosen stubborn oil particles. When the filter sits in cola, the acids slowly dissolve the sticky layers trapped inside the mesh. This means the grease lifts away without harsh chemicals or heavy scrubbing.
What Happens When the Filter Soaks in Cola
As the cola starts to work, you’ll notice the liquid becoming darker. That’s the grease dissolving and floating away from the filter. Areas that were completely clogged become clearer, and the filter starts to regain its original shine. After soaking, even thick, sticky residue wipes off easily.
When Cola Works Best
Cola is especially effective on:
- greasy extractor hood filters
- baked-on oils
- old residue that dish soap won’t remove
It’s not meant for burnt food, rust, or extremely damaged filters but for everyday kitchen grease, cola can work surprisingly well.
How it works
Cleaning your extractor hood filter with Coca-Cola is easy: Start by removing the filter from the hood and shaking off loose dirt. Place it in a large container or sink and pour Coca-Cola over it until the filter is fully submerged. Let it soak for one to two hours so the acids can loosen the grease deep inside the mesh. After soaking, wipe the filter with a sponge or brush, rinse thoroughly with warm water and let it dry. You’ll notice the filter looks cleaner, brighter and far less greasy all without using strong chemical cleaners. If you’re looking for an inexpensive and surprisingly effective way to deep-clean your extractor hood filter, this trick is definitely worth trying.
