What glass can and cannot take

  • Heat Use with care
  • Water and soaking Tolerates it
  • Acids, including vinegar Tolerates it
  • Strong alkalis Use with care
  • Solvents Tolerates it
  • Chlorine bleach Use with care
  • Abrasives Avoid

Always test on a hidden area first and let it dry before you treat the visible mark.

General rules for glass

Use diluted washing-up liquid and a soft lint-free cloth, rinse and dry. Avoid abrasive pads and sharp tools, and do not assume a coated or printed surface tolerates solvent or strong alkali.

Check the label

Identify untreated glass, safety film, printed glass, mirror backing or an easy-clean coating. Edges and adjacent sealants may be less tolerant.

Stains on glass

Glass can be damaged by a cleaner that is harmless on another surface. Identify the substrate, coating, finish and adjacent parts before treating a stain.

Use the least aggressive route

Use diluted washing-up liquid and a soft lint-free cloth, rinse and dry. Avoid abrasive pads and sharp tools, and do not assume a coated or printed surface tolerates solvent or strong alkali.

Judge only when dry

A remaining patch may be residue, a changed patina, coating loss or absorbed contamination. Stop if a hidden test changes colour, gloss, texture, adhesion or strength.
