  • Apply your regular car wash soap or clean.
  • Rinse your car thoroughly.

  • If you are using a polishing compound, you don’t need to wash again your car. Simply get a microfiber towel and gently wipe off the surface.
  • Continue wiping until the chemical is thoroughly removed.
  • Inspect your auto’s paint for any water spots you missed. If further work is needed, simply repeat steps 3 and 4.

I have included a video below on how to remove water spots from the car. Take note, however, that the water spot remover product used in the video is different from the one I have recommended above.

Personally, I would prefer the polishing compound because it is not only good at removing stains and marks but as well as hard water spots that have been troubling you all these times! If you use a compound, you don’t need to wash your car to remove the product after application.

The polishing compound serves as your final touch to polish your car’s paint and protects it from marks, stains, and sunlight. To complete your routine, don’t forget clean your windows.
