Here's a comprehensive guide about cooktop glass cracks and scratches:

Common Causes

• Heavy pots or pans dropped on the surface
• Dragging cookware across the surface instead of lifting it
• Using abrasive cleaning materials
• Thermal shock from placing cold items on hot surfaces
• Using damaged or warped cookware

How to Inspect

• Check the depth of scratches - superficial scratches may be repairable
• Look for spider web patterns that might indicate structural damage
• Examine if cracks extend through the entire thickness of the glass

DIY Solutions for Minor Issues

• For light scratches:
  • Clean the surface thoroughly
  • Use specialized glass cooktop polish
  • Apply with a non-abrasive cloth in circular motions

When to Call a Professional

• Deep cracks or scratches that catch your fingernail
• Any spider web cracking patterns
• Chips or cracks that go through the glass

Prevention Tips

• Always lift cookware rather than sliding it
• Use flat-bottomed, smooth cookware
• Clean spills immediately to prevent staining
• Use only recommended cleaning products
• Allow the surface to cool before placing cold items on it

⚠️ If you notice any deep cracks, stop using the cooktop immediately as it could shatter during use. This is a safety hazard that requires professional attention.
