Car Glass Anti Fog and Water Repellent Coating Spray

The bottle lives in the door pocket, and it comes out on the Sunday morning when you finally deal with the film on the inside of the windscreen.

It is a small job with a clear order to it. Wipe the glass down first so you are not spreading grit, mist the surface from the pump, spread the liquid out and then buff it dry. Ten minutes on a windscreen and the door mirrors, done in the shade rather than on glass that has been standing in the sun.

What arrives is a single slim black bottle with a fine mist pump, 100 ml or 3.38 fl oz by the label, in a printed sleeve. The bottle reads Car Glass Anti Fog Hydrophobic Coating Spray and carries the RayHong name. The maker lists enzyme preparations as the main ingredient, and that is the whole of the composition information published.

Key Benefits

• One bottle, hand applied No machine, no pad and no cure time on the sheet. Mist, spread, buff dry with your own cloth.
• Sized for the door pocket 100 ml in a slim bottle, small enough to keep in the car rather than on a garage shelf.
• For glass, inside and out The maker names windscreens and rearview mirrors as the surfaces, and lifting oil film from them as part of the job.
• Fine mist pump A pump head rather than an aerosol, so there is no propellant and you can aim it at a cloth instead of the glass when you want less overspray.
• Labelled clearly Net content, product name and maker name are all printed on the bottle you receive, not only on the listing.

Best for: drivers who deal with a greasy inside windscreen every autumn, and anyone who would rather keep a small bottle in the car than a bucket in the garage.

Why It Works

The interesting part of this product is where it is stored, not what it promises. A 100 ml pump goes in the door pocket, which means the job gets done at the petrol station on a Tuesday rather than waiting for a weekend with a hose. That is the honest argument for a small bottle of glass treatment, and it is the one we are making.

Quick Product Facts: 100 ml or 3.38 fl oz per the label; fine mist pump bottle; bottle and carton labelled Car Glass Anti Fog Hydrophobic Coating Spray, maker name RayHong; main ingredient listed as enzyme preparations; for vehicle glass and mirrors; packing list is one bottle.

How It Fits Your Routine

Do the inside of the windscreen first, on a cool day with the doors open. Wipe the glass with a damp cloth, let it dry, then mist, spread and buff. The inside is where film builds up and where a bottle this size actually gets used.

Outside, treat the door mirrors at the same time. They are small, they are the first thing that beads over in rain, and they take under a minute each.

Store it upright and out of the sun, keep it away from children, avoid contact with eyes and skin, and use it with the windows open rather than in a closed cabin. Follow whatever is printed on the bottle you receive.

FAQ

How long does one application last? The maker does not say. There is no duration on the bottle, none on the carton and none on the sheet, and we are not going to guess a number for you. Treat it as something you reapply when water stops beading the way it did.

What is actually in it? The only composition line the maker publishes is enzyme preparations as the main ingredient. No full ingredient list, no concentration and no shelf life is given. If you need the composition before you buy, ask us and we will ask the supplier.

Does it make driving in rain safer? We make no claim of that kind. The maker panels do put a driving safety statement on the product, there is no test behind it, and nothing sprayed on glass replaces working wipers, a clean windscreen and the speed you choose.

Does anything come with it? No. The packing list is one bottle. Bring your own clean microfibre cloth, and keep a second dry one for the buffing pass.
