Minor surface scratches on a glass tabletop are frustrating, but many can be significantly reduced — or even eliminated — using products you likely already have at home. The key is knowing which scratches are treatable and which need professional attention from a qualified glazier.
First: Assess the Scratch
Before reaching for the toothpaste, run a fingernail across the scratch. This simple test tells you a lot:
- Fingernail glides over it — a surface scuff or light scratch, ideal for DIY polishing.
- Fingernail catches slightly — a moderate scratch; home methods may help but results vary.
- Deep groove or crack — stop here. Deep scratches, chips, or cracks compromise the glass structurally and need professional assessment. Attempting to polish a crack can cause the glass to shatter.
Also check whether your tabletop is tempered (toughened) glass — common in modern furniture. Tempered glass is heat-treated for safety and cannot be cut or heavily polished without risk of shattering. If in doubt, contact the furniture manufacturer or a glazier before proceeding.
What You'll Need
- Soft, lint-free cloths (microfibre works well)
- Mild dish soap and warm water
- Your chosen polishing agent (see below)
- A spray bottle of clean water
- Painter's tape (optional, to protect surrounding surfaces)
Home Methods for Light Scratches
1. White Non-Gel Toothpaste
This is the most popular DIY method. The mild abrasive in toothpaste can buff out fine surface scratches.
- Clean the glass thoroughly with soapy water and dry it completely.
- Apply a small pea-sized amount of plain white toothpaste (not gel, not whitening formula with large abrasive particles) directly onto the scratch.
- Using a damp soft cloth, rub the toothpaste into the scratch in small circular motions for 30–60 seconds.
- Wipe away the residue with a clean damp cloth and inspect the result.
- Repeat up to three times if needed.
2. Baking Soda Paste
Mix equal parts baking soda and water to form a thick paste. Apply and buff using the same circular motion technique as above. This is a slightly gentler option than toothpaste.
3. Metal or Jewellery Polish
Products like Brasso (available at Bunnings or Mitre 10) contain fine abrasives designed for polishing hard surfaces. Apply a small amount with a soft cloth and buff gently in circular motions, then wipe clean. Always test in an inconspicuous area first.
4. Nail Polish (Clear, for Very Fine Scratches)
For hairline scratches that catch light, clear nail polish can act as a filler. Apply a thin coat over the scratch, let it dry, then carefully scrape away the excess with a razor blade held at a very low angle. This doesn't remove the scratch but can make it far less visible.
Tips for Best Results
| Tip | Why It Matters |
|---|---|
| Always work on clean, dry glass | Grit or dust can cause new scratches during polishing |
| Use light, consistent pressure | Too much force can worsen the scratch or damage coatings |
| Work in circular motions | Prevents directional streaking |
| Inspect in natural light | Artificial light can hide or exaggerate results |
| Don't over-polish | Excessive buffing can create a hazy patch around the scratch |
What Won't Work
Avoid using steel wool, abrasive scouring pads, or harsh chemical cleaners — these will create new scratches and potentially damage any protective coatings on the glass. Similarly, vinegar and lemon juice are acidic cleaners useful for mineral deposits, but they do nothing to remove physical scratches.
Limitations of DIY Methods
Home polishing methods work by very gently abrading the glass surface around the scratch to reduce its visibility — they don't truly fill or repair the glass. Results depend heavily on the depth and length of the scratch, the type of glass, and your technique. Manage expectations: you may achieve a significant improvement rather than a perfect result.
For laminated, coated, or tinted glass, be especially cautious — polishing can damage surface treatments. Check with the glass or furniture manufacturer before attempting any DIY repair.
When to Call a Professional
Contact a qualified glazier if:
- The scratch is deep enough to catch your fingernail firmly
- There are chips, cracks, or multiple scratches across a large area
- The glass is cracked — this is a safety hazard and the panel should be replaced
- Your tabletop uses specialised glass (laminated safety glass, low-E coated glass, or tinted glass)
- DIY methods haven't improved the appearance after several attempts
A professional glazier can assess whether polishing with specialist equipment is viable, or whether replacement is the safer and more cost-effective option. For safety glass in particular, MBIE Building Performance provides guidance on glazing standards under the NZ Building Code. You can find experienced local glaziers on tradedirectory.co.nz.
