Proper maintenance will ensure the longevity and appearance of your shower door:
- Cleaning Glass: Use warm soapy water and a soft damp cloth to keep the glass clean. Wipe dry with a clean cloth. Glass cleaner can be used if required. Avoid scourers, abrasives, and chemical cleaners as they can damage the glass and pattern.
- Hardware and Seals: Regularly check moving parts such as rollers and hinges to ensure they are secure and adjusted correctly. Tighten and adjust where required. Also check all sealed joints to ensure the seal has not deteriorated. Re-seal if required.
- ClearMax Coating: The ClearMax water-resistant glass coating helps prevent hard water stains and minimizes soap scum buildup, making cleaning easier.
