Rain X Rain Repellent Car Window Cleaner

Fancy improving not just how clean your cars windows are but how clean they stay when it rains? With Rain X rain repellent you could improve the visibility through your cars front windscreen by applying this product to your cars glass.


What is Rain X? It’s a product you can wipe on to your cars windows and it will help improve visibility in wet weather conditions.

The application of it is different to a car glass cleaner, you buff then solution in on to your cars glass in a circular motion and then let it dry. Then buff off with a clean, dry cloth and you will have then created a hydrophobic layer on your cars glass that helps repel water, bugs, dirt and even ice and snow too.

Review of Rain X Rain Repellent

Our review is mostly good, actually, it’s a very good product. We applied it just like the instructions and guide told us how, we’ve mentioned that above (we didnt use paper towel). We used the Rain X on all of our cars glass, including the side mirrors and front head lights.

It took all of 20 minutes to apply, let it dry off and then buff each window and before we applied it we made sure that the windows were already cleaned, we just used another product we were testing to sort this first step of the instructions out.

After we had finished, we filled up a watering can and played around with pouring water all over our car, oh what children we are. We were just very excited to see what this hydrophobic layer did to our cars glass and whether it would help.

On first inspection, it was really really good. Not only were our cars glass crystal clean, when we had poured the water over the glass it would run down and not leave a single trace it had been there, it also seemed to move quicker, maybe it did, maybe it didn’t, but it seemed like it did. We are thoroughly impressed with it, now it’s time to wait for the rains to arrive and to have a quick drive about.

Field Test of Rain X Rain Repellent

We waited a few days and eventually it rained, we went for a long hour drive out to a beach we like to walk our dog down the coast. As it rained and we drove through it, it was as good as it was the day we applied the rain-x, we were still very impressed.

On our return home, with just short of an hours drive being undertaken the front windscreen started to make a noise when the wipers were used, so this was all the time. When we got back, there seem to be some streaks on the front windscreen as well, which meant that the front glass was not as clear as when we had left.

We had driven before in the rain after using other car glass cleaning products and this hadn’t happened so we are led to believe that it was the rain x that created this.

Summary of Rain X

What we recommend and what we have learned about rain x and similar rain repellent products are that they are great and they do their job, well, but a couple of things always pop up.

Some we have read in reviews online and some we have witnessed ourselves.

It seems that using windscreen wiper blades which aren’t brand new with rain x doesn’t work. Maybe brand new windscreen wipers do, but for us it doesn’t.

People have suggested that it may only last a few weeks, we have gone nearly 3 weeks and our side windows still show better visibility than before we applied it.

Using rain x on your side windows seems to thoroughly improve the visibility and because there aren’t wipers, it should last, unlike the front windscreen of your car.

This is where Rain X really shines and works, at some T junctions, when it was raining, I could not see out of my side windows at all, luckily with electric windows I could drop them for the time I was sat at the junction, but this is dangerous and takes my eyes off of the road and what is happening. Secondly, with having clear and visible side windows, I can now see in my rear view mirror when it is pouring down too.

These are 2 things I didnt even think of improving, yet Rain x has done just that, I thought it would be great to see out the front better, but we have decent windscreen wipers and we keep our glass clean, it doesn’t actually need much more, the wipers do their job very well.


Pros & Cons

  • Drastically improved visibility of side windows on the car, this has helped tremendously whilst at T junctions and it’s pouring down. I haven’t seen anyone else mention this online and this is a big improvement for me
  • It’s easy to apply
  • Doesn’t cost much for what it does
  • The front windscreen for us, did not work that well, after an hour or so driving it streaked and made a squeeking noise

Conclusion & where to buy

Do you need a rain repellent? If we had just tested the front car windscreen, we would probably give it a miss as it didn’t help us all that much, it looks like others have had great success though.

Where it did help was with the side windows and rear view mirrors on the side of the car. I can now see, no matter how much its raining what is happening when im at a T junction and I no longer need to open the windows to get a safe view of the road.
