1. Remove rust spots
Whether the suction plate or the electromagnet is rusty, the first thing to do is to find a way to remove these rust spots. The common ways to remove rust spots are as follows:
(1) Scrape with a knife: Use a knife or a small fruit knife that is not used at home to carefully scrape off the rust spots on the door suction;
(2) Soak with vinegar: Pour an appropriate amount of vinegar directly on the door stopper, or use a soft cloth to moisten the vinegar, then wring out some, and wipe the door stopper vigorously until the rust spots on it are gone.
(3) Sanding paper: You can also use sanding paper to sand the rust spots, but you need to choose a finer grained sanding paper, so that the sanding effect will be better.
2. Clean the door stopper
After removing the rust spots, wet the door with a soft cloth and clean the door to make sure it is neat and tidy. Finally, wipe off the water stains with a dry cloth.
3. Test whether the door stopper can be used normally
After carrying out the above two steps, the next thing to do is to test the door. Open it and see if the suction plate and electromagnet can suck properly. If you find that the door stopper still cannot be sucked after the test, you need to replace it with a new one.
4. Polish the door stopper
If it is determined that the door stopper can be reused, you can use professional polishing powder to polish the door stopper to make the door stopper look like new.
