Car Window Coating & Cleaner

A dirty windscreen doesn’t just look unsightly, it has an adverse effect on your ability to drive safely. It reduces your ability to see clearly, particularly at night and in wet conditions, and so you need to take action to reduce the risk of an accident.

Why Car Window Coating is the Best Course of Action

Although a vehicle windscreen appears to be hard and shiny glass, the surface of it is covered in microscopic holes. These holes attract dirt and grease that stick to the surface and make the glass difficult to see through.

A conventional solution is to use your windscreen wipers with a spray of water and cleaning solution from the washer bottles. In dusty or windy conditions, that only has a very short effect because grime quickly reappears.

Normal washing of the windscreen, either by hand or using a carwash, is also only a temporary solution. Although the appearance will be improved, dirt will soon reappear and the problem will be on-going.

The continual coating of the windscreen with dirt is partly due to the nature of the windscreen, in that the microscopic holes will continue to attract dirt. That can seriously increase the dangers of driving by making it more difficult to see clearly. To avoid this situation, use a specialist car window cleaning product.

Use Crystal — the Best Car Window Cleaner on the Market

Some window coating products are short-lived, largely ineffective and can lock in dirt on windscreens so the problem is made worse. Crystal cleaner for car windows, however, is a natural product that provides dependable protection against dirt, grease and liquids. It applies a glazed coating to clean glass surfaces and masks the microscopic holes that attract dirt.

The coating will typically last 6 to 12 months, depending on whether your vehicle is stored outdoors or under cover, before needing to be re-applied. During that period, glass will remain much cleaner, visibility will be improved dramatically and cleaning of the windows will be much easier.

Rain on untreated glass tends to form into small droplets that stick to the surface and need to be cleared from the windscreen by regular use of the wipers.

After treatment with a car window coating, rain combines into larger drops that are dispersed by natural airflow over the moving vehicle, taking any dirt with them. The result is that wipers are used less frequently and visibility is much improved with no streaking.

Cleaner and drier windscreens mean increased visibility, particularly at night and during wet weather, less glare from approaching headlights and improved driving safety overall. Seeing things better reduces response times and stopping distances in emergencies, so you’re a better driver due to using an effective car window cleaner.

This product is a professional use product, however there are no professional skills required. The detailed instruction guide with pictures is attached therefore everyone can use the product and derive the same finishing by following the instructions.


If you were not satisfied with other products for window coating, Window Crystal certainly delivers the differences to exceed your expectations.



Window Crystal is fluorine based and will never be oxidized and deteriorated



The great majority of window coating products sold in the market is silicon based. The silicon based products is going to have oxidation. A coating film on a glass after oxidization and deterioration stays as just oil film. This oil film does not have any water repellent effect and actually this is the cause of low visibility. Plus, re-coating silicon based coating on glasses will leave permanent marks and scales on glasses.


Consequently, utilizing silicon base window coating products let window conditions get worse than before applications.



Window Crystal is superior compared to other window coating products because of its pure fluorine based coating agent that is not oxidized and deteriorated.



The water repellency lasts more than 6 months, although a car is parked outdoor



Because of the fluorine ingredient, water repellency should last more than 6 months for a car parked outdoor and more than 12 months when a car is parked inside.
It is actually fun to see raindrops are repelled when you are driving in the rain. Window Crystal makes your driving easier and also more enjoyable.


If you have been using other window coating products, please engage Oily Film Clean to remove oil film on glasses before applying Window Crystal.

work as promised and great

I was so curious this window coating as never tried any car care items on windows and I thought it could be wasting. I was wrong as it actually creates great water proof protection and it is fun to see waters blew away in a rainy day and even when I wash my car. great product to use

Extremely storong

I used to use one from Supercheapauto but ran out it so that I tried this. This water proof coating is far more strong than the one from Supercheapauto, rains start flowing after 40kmh and they are completely slipped after 60kmh. Recom' to use all of glasses.

Anthony A.

Extremely strong water proof effect, no doubt.
