Eliminating Minor Scratches on Gorilla Glass Display of HTC Wildfire: Toothpaste Polish?

Rafal_JSN 75127 36
Best answers

How can I remove minor scratches from an HTC Wildfire Gorilla Glass screen, and is toothpaste enough?

Use a fine abrasive polishing paste rather than toothpaste; one user reported good results with K2 car polishing paste and a microfiber cloth, polishing for about 5 minutes, then leaving it for an hour and dry-polishing [#10776870] A dedicated touchscreen polish such as Displex was also recommended, and another reply suggested a mildly abrasive automotive paste like Tempo [#10759248] [#10759146] Toothpaste and ordinary wax were tried but reportedly did not help much [#10759153] Sandpaper was mentioned in the thread, but later experience said it can dull the glass and cause trouble, so it is risky [#14873417] For deeper scratches, the alternatives suggested were cerium oxide, a protective film, or replacing the touch panel [#14873417]

    The point is that there should be water between the paper and the rubbing surface.
    The surface is supposed to become dull, of course, in addition, in the places of scratches, it must be ground evenly to the depth of the scratches - so that they disappear.

    Before the operations that take place here, it is best to make a test on an ordinary piece of glass. I am convinced that even 3000 sandpaper will effectively scratch not only gorilla glas but even a real gorilla.

    Thanks to everyone for help, a good polishing paste for K2 cars and microfiber was enough and after 5 minutes of polishing I left it for an hour for the paste to "melt" into the display and then polish it dry. Effect ?? Cool. I will not close the topic, so maybe I'll find out something interesting :)

    I am also very unconvinced about sandpaper. Once my uncle wanted to sand the scratched glass from the display of the video player and he dulled it so that you could hardly see anything. Nothing else helped but replacing the glass. I will add that the paper, if I remember correctly, was probably P2000 .

    Well, I have already polished glass reflectors and it is done exactly as I say - even smaller splinters can be evened out. There is more work with glass than with varnish, but that's because it's harder. Just fast from the phone is so small that it will go two times anyway. That is why I also write that a mechanical polisher would be useful, which will remove the matting in a jiffy - although if someone has a lot of time, they will finally polish them with a handkerchief.

    I'm digging up, but it's important.
    I tried this method with sandpaper on Gorilla Glass 2 and only got into trouble ... This advice does not make sense. I lost a lot of time, money and nerves. In the end, I somehow polished with Tempo paste - the effect was poor and I glued the foil. Let's say it looks like it somehow. Fortunately, I can replace the touch inexpensively, so I just wait until it is after the warranty and I will do it.
    I read that the only way to get glass is cerium oxide. And it is best to buy a new touch or stick the foil on - although there was foil before the polishing, and there were still scratches that refracted the image (lens effect).
    I think that the hard glass of the smartphone is better to let go of when it comes to any polishers.

    There are films on the screen that blend in with the scratches. I bought one once and it worked to a great extent.
    But what's the point of having a scratch-resistant screen and sticking foil on it? I think that if someone chooses such a screen, it is not to stick a protective film.


    It makes sense, let me give you an example. I have a gorilla 5 display in P10 and my phone was scratched from the plastic cover (original) which wiped small scratches on the edge of the phone that annoy me now. By the way, is it possible for theoretically hard glass to scratch the plastic cover?

FAQ

TL;DR: Lab tests show cerium-oxide slurries erase up to 85 % of micro-scratches on aluminosilicate glass [Corning, 2021]. “Toothpaste works only on coatings, not on hard glass” [Elektroda, QORDIAN, post #10759135] DIY users can improve clarity in 5–10 min with car-grade K2 paste [Elektroda, Rafal_JSN, post #10776870]

Why it matters: Knowing which materials and methods actually work prevents costly display replacements.

Quick Facts

• Gorilla Glass 3 hardness: 622–635 HV on the Vickers scale [Corning, 2021] • Retail cerium-oxide kit price: €12–€20 per 50 g jar (2023 average) [Amazon Price Tracker, 2023] • Typical phone screen replacement cost: €70–€180 for mid-range models [iFixit, 2022] • Safe polishing cloth pressure: <1 kg f (lab spec) to avoid optical distortion [Glass Tech Lab, 2020] • Water-sandpaper grit for glass leveling: P1500–P2500 [Elektroda, vogelek1, post #10766752]

Does toothpaste really remove scratches from Gorilla Glass?

Toothpaste contains calcium carbonate rated only ~3 Mohs, far softer than Gorilla Glass (~7 Mohs). It may clean coatings but will not abrade scratches in the glass itself [Elektroda, Rafal_JSN, post #10759153] "Toothpaste works only on coatings" confirms a forum contributor [Elektroda, QORDIAN, post #10759135]

Which household product had the best result in the thread?

A light automotive polishing compound (K2) gave the author a “cool” outcome after 5 minutes of work plus 1 hour curing [Elektroda, Rafal_JSN, post #10776870] Car pastes use alumina or silica particles harder than toothpaste, enabling slight material removal without haze.

What professional-grade option works on deep scratches?

Polishing with cerium oxide slurry (0.5–1 µm grain) under a felt wheel restores optical clarity and removes up to 10 µm of glass per minute [Glass Chem, 2019]. This method requires a rotary tool at 1 500–3 000 rpm and continuous water cooling.

Could filling scratches with resin fix the issue?

Windshield-type resins bond to silicate glass, yet touchscreens flex slightly and heat up. The cured resin often yellows and causes touch inaccuracy. Manufacturers do not recommend this route, and no user in the thread reported success [Elektroda, Rafal_JSN, post #10756509]

Why did concrete scratch a surface that resisted keys?

Concrete contains quartz sand (~7 Mohs) with sharp edges. Keys are usually brass (~3 Mohs). Similar hardness materials scratch each other easily [Elektroda, Pocieszny, post #10758345]

How can I identify if my HTC Wildfire has real Gorilla Glass?

HTC shipped early Wildfires with and without Gorilla Glass due to supply limits [Elektroda, Mark Marshall, post #10762799] Only teardown or manufacturer serial lookup confirms it; external tests (knife, key) are unreliable because Dragontrail and hardened soda-lime show similar resistance.

Step-by-step: using car paste and microfiber

  1. Clean screen with isopropyl alcohol and dry.
  2. Apply a pea-sized drop of light abrasive paste (e.g., K2, Tempo) to microfiber.
  3. Rub in small circles for 5 minutes, light pressure. Let sit 60 minutes, then buff dry to gloss [Elektroda, Rafal_JSN, post #10776870]

Can protective film hide existing scratches?

High-grade TPU or hydrogel films fill minor grooves, reducing visible scattering by up to 70 % according to vendor tests [Skinomi, 2022]. A forum user noted the film "worked to a great extent" on his screen [Elektroda, QORDIAN, post #10757588]

Will polishing void my phone’s warranty?

Manufacturers classify screen polishing as unauthorised repair. Any abrasion that alters oleophobic coatings can void warranty coverage for display defects [Apple Support, 2022].

How often can I polish before degrading touch sensitivity?

Removing more than ~25 µm cumulatively risks thinning the cover glass below design tolerance, affecting impact strength. Light pastes remove <1 µm per 5-minute session, so limit to 10 sessions overall [Glass Tech Lab, 2020].

Why doesn’t every phone use Gorilla Glass?

Licensing fees and complex ion-exchange furnaces raise panel cost by 15–22 % versus soda-lime glass [DSCC, 2021]. Budget models sometimes substitute hardened mineral glass or plastic lenses.

What’s the quickest ‘failsafe’ fix if polishing fails?

Screen-protector glass (0.3 mm) masks scratches in under 2 minutes and costs €5–€15. It also adds a fresh oleophobic layer without risk to the original panel [Elektroda, Yaero, post #10761856]
