Step 2 – Apply the Shampoo

Be careful when applying, you want to use the needed amount of cleaning shampoo. A few drops should be enough for a single trim. 

Apply the cleaning solution to every window trim, and then let it sit for a while. 

Step 3 – Scrub with the Brush

After a few minutes of applying the shampoo or other cleaner, take the brush and start brushing the trim. As mentioned before, the brush needs to be soft, hard brush will scratch the trim.

Once you are done scrubbing, wipe off the cleaning solution with the microfiber cloth and rinse it thoroughly. Then check if the trim is cleaned properly, if not, repeat the process again.

Once the exterior trims dry properly you can apply the trim protectant. 

Importance of Cleaning Rubber Trims Regularly

  • It improves the functioning of rubber trims, hence the windows remain clean.

What’s the Purpose of Rubber Trims around Car Windows

It is hard to find a thing in vehicles that don’t serve any purpose. Doesn’t matter how tiny or insignificant it looks, it surely comes with a purpose. 

Rubber trims are meant to keep the window clean and seal the windowpane.

Vehicles are always into the dirt, insects, moisture, etc. You must have noticed that there is a gap around the window which the rubber trim seals, right?  Without the rubber trim, dirt, moisture, insects, etc., would have gone inside and slowly cause corrosion.

And the worst part is, you won’t even know until you open and check inside the door. 

You also know that these rubber trims keep the window a little squeezed, and that is because when the window rolls down, the trim can remove dust, dirt, or anything. 

Though rubber is a long-lasting material, rubber car trims wear out and get hard sooner than expected.

When trim gets hard, it loses the ability to seal and clean the windows. One major reason behind rubber trim’s short lifespan is the UV-ray. 

How Often Should You Clean the Rubber Trim?

Well, there isn’t a rule or time frame for that. You should clean the rubber trims whenever you feel the need. Check the exterior trims around the window, and if you see they are dusty or fading, then it is time for a thorough cleaning. 


When should you replace the rubber trim on your car window? 

Anything that reaches its threshold point starts breaking off. So, if you see your car window rubber trim has become flaky and breaking off, it’s better if you do replacement rather than restoration.

Can you use regular shampoo instead of automobile one?

Yes! You can. But automobile shampoo is made for a purpose, and it stays longer on the surface, helping to wipe off the dirt easily. Regular shampoo can be a substitute but don’t expect the same result as an automobile one. 

Why is window rubber trim important?

Rubber trims are essential for keeping your car clean and safe from contaminants. It keeps dirt out of your car and keeps the interior temperature sturdy.
