How should Madras® glass be looked after?
Etched glass is more delicate than transparent float glass because of its surface characteristics.
When mechanically processing: wash with clean water and immediately dry in an automatic drier after each stage of mechanical processing; this prevents cerium and scale from depositing in the micro-interstices of the satin finish.
When installing: care must be taken not to soil the satin-finish with putty, resins, sealing, etc.; each of which requires a specific solvent to remove.
Routine maintenance: use a solution of water and/or a standard glass detergent. Dry immediately with a perfectly clean microfiber cloth, wiping repeatedly but gently in the same direction.
