The Seven Golden Rules of Care

  • A secure grip is essential – never hold the glass by the base or stem while washing or polishing. Always cradle the bowl gently.
  • Hand washing remains the gentlest and highly preferred method of cleaning.
  • A high-quality dishwasher with a dedicated crystal or delicate cycle is also an excellent option. 
  • Temperature matters – set your dishwasher to a gentle cycle that does not exceed 65°C / 150°F.
  • Release the steam – crack open the dishwasher door as soon as the cycle ends to let residual moisture escape."
  • White vinegar works wonders against hard water stains and dullness, restoring the crystal’s natural brilliance.
  • Use a good-quality cloth when polishing, but for the best results, pair it with our Izaak Reich Profi Propolish cotton polishing gloves.
