I.Water filter for faucetsCleaning steps
1、 Add 40ml of concentrated dishwashing detergent to a 1-liter clean, airtight bottle. Then, add 1 liter of warm water and seal the bottle. Gently shake to mix thoroughly.
2. Pour the diluted cleaning solution into the container, and then place the separator and related parts flat on the container. If the dirt level is high, you do not need to dilute the concentrated dishwashing detergent; instead, you can pour the concentrated dishwashing detergent directly into the container for use.

3. Soak for 20 minutes. Remove the separator after soaking.
4. Use a toothbrush to clean the water filter, diverter, and related components. For stubborn stains, apply cleaning solution directly to the affected areas with a handle-style sprayer and then scrub with a toothbrush.
5. Rinse the separators, dust screens, and related components thoroughly with clean water.
6. Inspect and clean the surface again using a new cleaning solution and repeat the steps above.
7. Reassemble the white and black gaskets. Return the reassembled gaskets to the separator.
8. Reinstall the white mesh (with the concave side facing up). Reinstall the dust-proof mesh.
9. Reconnect the parallel water pipes with the diverter and reinstall the diverter in the faucet. After allowing the water to flow for 5-10 seconds, the faucet should function normally.
Two. How to clean water stains on the faucet.
1、Mix vinegar, baking soda, and water in a spray bottle. Shake well until a white, foamy substance forms. Place the spray bottle aside. Place a paper towel around the faucet. Then, spray the mixture onto the paper towel-covered faucet. Allow it to sit for 30 minutes to 1 hour. Remove the paper towel and rinse the faucet with clean water. Finally, wipe the faucet clean with a clean cloth.
2. Use a clean sponge to scrub the affected area. Slightly dampen the sponge, then apply a small amount of toothpaste. Scrub the area thoroughly. You will notice that the scale gradually disappears. Finally, rinse thoroughly with clean water.
