When to Use Gla-C

Clear Vision for the Toughest Conditions.

Bad Weather Preparation

Heavy Bug & Sap Season

Interior Detailing & Tints

Gla-C is your dedicated specialist for the moments when standard multi-surface coatings aren't quite enough for your glass.

Apply it before the rainy season or winter storms to create a hyper-slick barrier that repels water, sleet, and snow.

Use it after a long road trip to safely dissolve baked-on bug splatter and tree sap without intense scrubbing that could scratch your glass.

The perfect go-to for removing interior off-gassing haze, vape film, and fingerprints on delicate, aftermarket tinted windows.

Step 1: Lightly Mist

Spray Gla-C directly onto the glass surface or onto a clean 16" Microfiber detailing towel. A light mist is all you need.

Step 2: Lift the Grime

Wipe the glass thoroughly to safely dissolve and lift bug splatter, tree sap, interior off-gassing, or road film.

Step 3: Buff to Clarity

Immediately flip your towel to a dry side, or use a second, completely dry microfiber towel, and buff the glass to a flawless, streak-free finish.

What is Gla-C®?

Gla-C is our glass cleaner and polisher in one. It is a true cleaner, and it will leave a streak-free shine.

Can I use Gla-C® on my windshield, inside and outside?

Yes! Gla-C is made to be used on all glass, window film, acrylics, & isinglass.

Is Gla-C® safe to use on window tint?

Absolutely! Gla-C will clean and protect window tint without causing any peeling or cracking.

Why would I use Gla-C® instead of F11 or F11PRO on my windshield and windows?

Gla-C will clean and polish your windows at the same time. You do not need to wash that surface beforehand to use Gla-C, which is one of the main benefits of Gla-C.

Will Gla-C cause streaks?

No, Gla-C is formulated to leave a streak-free shine and give optimal optical clarity, so windows, windshields, glass, and mirrors are left crystal clear.

Reviews

Streak free windows

"I have cleaned my vehicles inside and out for the past 53 years as they always seem to run better when they look nice. It seems something has happened in the recent past with the traditional glass cleaners as they require more work to get a streak free finish. I bought a small bottle of Top Coat's GLA-C and it worked like a champ. So now I buy it by the gallon."

Great Kit and service!!

"Works really well on all glass, car, house windows ect. Wish I found it sooner!"

— Tom S. (5/5)

"Product seems to do as they say. Car looks great inside and out. I live on a dirt road. It's one mile drive on dirt to get to asphalt . I like my vehicles looking clean. I've only have had it on for a couple weeks and I am amazed on the tire product on how clean my tires are staying. I'll come back in a few months with pictures and give a review. I'm using nothing but Top coat products for panit,windows and tires. Living on a dirt road is a challenge for someone who wants a clean looking car. This will be a real test."
