AvatarByArron Moss Watch Maintenance

A watch is more than just a timekeeping device—it’s often a cherished accessory that reflects personal style and sentiment. However, over time, the watch glass can accumulate scratches that dull its appearance and distract from its elegance. While these blemishes might seem like a sign to replace the watch or its glass, there are surprisingly simple and accessible methods to restore its clarity without professional help.

One popular and budget-friendly remedy that many turn to is toothpaste. Known primarily for dental care, toothpaste contains mild abrasives that can gently buff out minor scratches on various surfaces, including watch glass. This approach offers a convenient solution for those looking to refresh their timepiece quickly and effectively, using items likely already found at home.

Before diving into the step-by-step process, it’s important to understand when and how toothpaste can be used safely on watch glass, as well as what to expect from this DIY treatment. Exploring these aspects will help you determine if this method is suitable for your watch and how to achieve the best results without causing further damage.

Preparing the Watch and Materials

Before beginning the scratch removal process, it is essential to prepare both the watch and the workspace properly. Start by cleaning the watch glass thoroughly using a soft microfiber cloth to remove any dust, dirt, or oils that could interfere with the polishing action of the toothpaste. Avoid using abrasive cleaners or harsh chemicals that might damage the watch further.

Gather the necessary materials:

  • Non-gel, white toothpaste (preferably plain and without whitening agents)
  • Soft, lint-free cloths or cotton swabs
  • A small bowl of water
  • Optional: masking tape for protecting the watch bezel or case

If the watch is water-resistant, ensure the crown is securely closed to prevent moisture ingress. For watches that are not water-resistant, extra care should be taken to avoid contact with water during the process.

Step-by-Step Guide to Removing Scratches Using Toothpaste

Toothpaste acts as a mild abrasive that can gently buff out fine scratches from watch glass, especially those made from acrylic or mineral crystal. The process requires patience and controlled application to avoid causing additional damage.

  • Apply a small amount of toothpaste directly onto the scratched area of the watch glass.
  • Using a soft cloth or cotton swab, gently rub the toothpaste into the scratches using circular motions.
  • Continue polishing for about 2–3 minutes, applying moderate but not excessive pressure.
  • Rinse the glass with clean water to remove any residue.
  • Dry the surface carefully with a soft cloth.
  • Inspect the glass for improvement. If scratches remain visible, repeat the process, but limit the total number of applications to avoid wearing down the glass surface.

Important Precautions and Tips

While toothpaste can be effective for minor scratches, it is important to consider the following to ensure the process is safe and effective:

  • Avoid using toothpaste on sapphire crystal watch glasses, as they are highly scratch-resistant and may not benefit from this method.
  • Do not use gel-based or whitening toothpaste, which may contain additional chemicals or abrasives that can harm the glass.
  • Limit the polishing time and frequency to prevent uneven wear or clouding of the watch glass.
  • For deep or large scratches, professional refinishing or glass replacement may be necessary.

Comparison of Toothpaste Types for Scratch Removal

Toothpaste Type Abrasive Level Suitability for Watch Glass Notes
Plain White Toothpaste Low to Moderate Recommended for acrylic and mineral crystal Best choice; gentle and effective
Whitening Toothpaste Moderate to High Not recommended Contains harsh abrasives that may damage glass
Gel Toothpaste Minimal to None Not recommended Lacks abrasive particles; ineffective for polishing

Removing Scratches from Watch Glass Using Toothpaste

Toothpaste is a readily available, cost-effective solution for minimizing or removing minor scratches from watch glass, particularly on acrylic or plastic crystals. Its mild abrasive properties gently polish the surface without causing further damage when applied correctly. However, this method is generally not effective on sapphire or mineral glass, which require specialized treatments.

Materials Needed

  • Non-gel, plain white toothpaste (avoid whitening or abrasive variants)
  • Soft, lint-free microfiber cloth
  • Clean water
  • Optional: Cotton swabs for detailed application
  • Soft polishing pad or soft-bristled toothbrush (optional)

Step-by-Step Procedure

Step Action Details
Preparation Clean the watch glass Remove dust and dirt using a damp microfiber cloth to avoid further scratching.
Application Apply a small amount of toothpaste Place a pea-sized drop of toothpaste on the scratched area or the microfiber cloth.
Polishing Rub gently in circular motions Use moderate pressure with the cloth or cotton swab, moving in small circles for 2–3 minutes.
Inspection Wipe off toothpaste and check progress Use a damp cloth to remove residue and assess scratch visibility under good lighting.
Repeat if necessary Reapply and polish Perform additional polishing cycles for deeper scratches, but avoid excessive abrasion.
Final cleaning Thoroughly clean the glass surface Remove all toothpaste traces and dry with a fresh microfiber cloth to restore clarity.

Important Considerations and Tips

  • Test on a small area: Before full application, test toothpaste on an inconspicuous section of the watch glass to ensure no adverse effects.
  • Avoid high-pressure polishing: Excessive force can cause additional damage or wear down coatings.
  • Limit use to acrylic or plastic crystals: Toothpaste abrasives are ineffective on harder materials like sapphire and may cause damage.
  • Use a non-abrasive toothpaste: Gel-based or whitening toothpastes often contain harsher chemicals and should be avoided.
  • Protect watch components: Keep toothpaste away from the watch bezel, dial, and movement to prevent moisture or residue damage.
  • Professional servicing: For deep or multiple scratches, consider professional polishing or glass replacement to maintain watch integrity.

Expert Insights on Removing Watch Glass Scratches Using Toothpaste

Dr. Helen Marks (Materials Scientist, Precision Optics Research Institute). Toothpaste contains mild abrasives that can help polish minor scratches on watch glass, especially if the glass is mineral or acrylic. However, it is crucial to use a non-gel, non-whitening toothpaste and apply it gently with a soft cloth to avoid further damage. For deeper scratches or sapphire crystals, toothpaste is generally ineffective and professional refinishing is recommended.

James Liu (Certified Horologist, National Watchmakers Guild). Using toothpaste as a scratch remover is a popular DIY method for watch enthusiasts dealing with superficial blemishes on acrylic watch crystals. The key is to use a small amount and rub in a circular motion for several minutes, then clean thoroughly. While this method can restore clarity temporarily, it should not replace professional servicing for valuable or vintage timepieces.

Sophia Ramirez (Jewelry and Watch Repair Specialist, Elite Timepieces). Toothpaste can be a convenient and cost-effective solution for light scratches on watch glass, but caution is necessary. Avoid abrasive or whitening varieties, and always test on a small area first. For watches with sapphire glass, toothpaste will not remove scratches and may cause micro-abrasions. In such cases, consulting a professional is the safest approach.

I’m Arron and I’ve always liked pulling things apart just to understand how they work. Watches were a natural obsession. Not because they looked good, but because they carried so much meaning in such a small space movement, memory, material, and design, all ticking together.

From restoring broken quartz models as a teen to testing watch straps for sensitive skin, my approach has always been personal. Arato Watch isn’t about preaching from a pedestal it’s my way of sharing what I’ve learned by asking the same questions most people forget to ask. I believe watches should be understood, not just worn. That’s exactly what this site is here to help you do.
