Remove Water Marks on Auto Glass – Do It Yourself

All vehicles will be contaminated from water marks on glasses eventually either through improper drying methods or due to rain water left over on the auto glass for a period of time. There is no exception to my Toyota Vios glasses too. I’d never remove my Toyota Vios’s water marks on the windscreen and glasses since I bought the car more than 2 years ago. You can see how obvious the water marks on the rear windscreen at below image:

It is so irritating to see the watermarks on the glass and it is dangerous to the driver as well because the watermarks prevent the driver from having clear vision through the glass especially when the driver driving in the night time.

Let’s check out how I removed the watermarks on the windscreen and glasses.

I bought a Waxco WaterMarks Removers from 99’s Auto Accessories Shop which cost me only RM15.90.

The package came with 2 hand gloves as a protection for the users’ hands because the mixture of the remover is acidic and may burn the users’ hands.

Step by step to remove the watermarks on the car’s glasses:

  1. Clean up the windscreen surface and ensure the surface is dry.
  2. Put the water marks remover on the cloth and scrub the cloth on the affected windscreen. Poor the remover on the cloth if the liquid is not sufficient. The watermarks can be removed easily if you pour more of the WAXCO Watermarks Remover onto the cloth.
  3. Keep on scrubbing the windscreen with the cloth until the watermarks are removed completedly.
  4. Ensure the remover does not get on the body paint or plastic parts as it may etch the outer layer away.
  5. Once completed, rinse the glass and car body with plenty of water to ensure the acid is completely removed from the car, especially the car body.
  6. Proceed the removal process to other glass parts that contaminated with water marks.
  7. Repeat steps 1-5 or each part.

    Hi Kelvin, I tried using the waxco watermark remover but I accidentally dropped droplets on the windshield and the marks won’t go away even after washing with a lot of water. Please advise on how to remove the marks left behind by the watermark remover please. Also, I feel like my windscreen become more oily? I tried washing with car shampoo to no avail. Please help!

      Hi Stephanie,
      The Waxco watermark droplet can be removed with Waxco watermarks effectively. Just pour the content on the surface, and scrub hard on it and wash it away with clean.

      The oily on the surface windscreen can be removed with dish detergent. Let me know the result, Step 🙂

    My car windows previously have rain x applied to them. Can I still use watermark removal of it will cause further damage?

      Hi Kelvin,
      we got same name 🙂
      No worry, the watermark removal won’t cause any further damage.
      The watermark removal will remove the watermark on the screen together with Rain X coating.
      It is advisable to re-apply again the Rain X after you had removed the watermark.

    Hi
    Kelvin,
    I have a problem with my Toyota Vios tail-light and brake-light system.During night driving my left side tail-light goes off when I applied my brake.
    Please advise what is the reason for it.

    Thanks & best regards.

    Ken

    1. Kelvin Ang says:

      Hi Ken,
      Thanks for drop by.
      Your break light issue might be due to bad connection from the break light switch. Did you perform any installation or modification recently?
      The best is head back to that accessories shop and let them fix it.

      our brake light got 2 bulb filament, 1 is normal brightness, the other 1 is brighter for the moment you applied brake. i guess the brighter filament is fried, just change the bulb will do.

      1. Kelvin Ang says:

        Thanks Selson for the explanation!
        you are awesome! 🙂

    Nice tip, but in Penang, very likely birds’ poo will land on our cars, any tips of preventing that? hahahahaha! #justaskforfunanyway 😛

    1. Kelvin says:

      hahaha! That is a funny question, Ken!
      I think there is only ways to minimize it, don’t park your car under the tree!
