A rangehood filter can look clean on the surface and still feel greasy because cooking residue sits throughout the layers of the metal mesh.
If the wash water is too cool, the cleaning solution is already loaded with grease, or the filter is rinsed too quickly, loosened residue can remain inside the mesh and spread back across it as it dries.
Use warm or hot water and a cleaner suitable for the filter material, give it time to work, then gently clean and rinse from both sides. More scrubbing is not always the answer; thorough rinsing is often what removes the final greasy feel.
Check the manufacturer’s instructions before using strong degreasers or a dishwasher, especially with aluminium filters.
