Glass Guard, Glass Cleaner, Automotive Oil Film Cleaning Brush
Night rain. Oncoming headlights. Total glare.
It's not your wipers. It's the oil film on your glass.
That blinding starburst at night and the greasy haze your wipers leave behind come from an invisible layer of oil film baked onto your windshield. Washer fluid can't remove it. Glass Guard can, in about 2 minutes.
Sound familiar?
- Headlights turn into halos and glare when it rains at night
- New wipers, but they still chatter, squeak and skip
- Every wipe leaves a foggy smear you can't see through for a few seconds
- You cleaned the glass yesterday and it already looks hazy again
Why regular glass cleaner doesn't fix it
Exhaust fumes, asphalt vapor, tree sap and silicone from aging wiper blades build up on your windshield. Sun and engine heat bake them into a hard, oily film.
Washer fluid and household glass cleaner only remove loose dust on top. Glass Guard's high-penetration emulsion breaks down the baked-on film itself, so water sheets off evenly instead of smearing, and light passes through cleanly instead of scattering into glare.
3 steps. One hand. No mess.
The cleaner is stored inside the brush, and the flexible pad follows the curve of your windshield. You don't need a spray bottle, sponges or gloves.
Open & press
Remove the cap and press the pad lightly against clean, cool glass (not in direct sun) to release the emulsion.
Scrub in circles
Work in small overlapping circles, section by section, including the edges and the area under the wipers.
Rinse thoroughly & dry
Rinse with plenty of clean water before it dries, then wipe dry with a microfiber towel. Water should now sheet off evenly.
Pro tip: Wipe your wiper blades with a damp cloth too. Dirty blades smear old grime straight back onto freshly cleaned glass.
Protect your paint: Press gently and keep the brush upright. Wipe off any drips on paint or trim right away.

What drivers are saying
Frequently Asked Questions
Will it scratch my windshield?
Used as directed on a rinsed, grit-free windshield, it lifts the oil film without harming the glass. Always rinse off loose sand and dust first, since grit under any pad can scratch.
Is it safe for tinted or coated glass?
Car window tint film is applied to the inside of the glass. Glass Guard is used on the outside, so it doesn't touch your tint. Don't use it directly on tint film. If your windshield has a ceramic or rain-repellent coating, the deep clean may remove it.
Will it leave streaks or residue?
Not when it's rinsed off properly. If you see a white haze, the emulsion dried before rinsing. Rinse again with plenty of water and wipe dry. Work on cool glass in the shade and rinse each section before it dries.
My glass got hazy again after a few days. Why?
Usually the wiper blades are spreading old grime back onto the glass. Clean the blades (or replace worn ones) when you clean the windshield.
Does it really help in rainy conditions?
Yes. Once the oil film is gone, water sheets off evenly instead of smearing, and headlight glare is reduced. For long-lasting water beading, apply a dedicated rain-repellent coating afterwards.
How often should I use it, and how long does a bottle last?
Most drivers clean every 1–2 months, or whenever night glare comes back. One bottle gives about 4–6 full windshield cleanings, depending on how dirty the glass is.
Will it leak in my car?
Keep the cap on and store the brush upright. Avoid leaving it in a very hot car for long periods.
Can it be used on home glass surfaces?
Absolutely. It works well on mirrors, windows, shower glass and other smooth glass surfaces.
