6. Maintenance
Regular cleaning and maintenance will keep your DreamLine shower door looking new and functioning properly.
- Glass Cleaning: Use a soft cloth and a non-abrasive glass cleaner. Avoid abrasive cleaners, scouring pads, or harsh chemicals that can damage the glass or hardware finish. For best results, wipe down the glass after each use to prevent water spots.
- Hardware Cleaning: Clean metal hardware with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the finish.
- Seal Maintenance: Periodically inspect the vinyl seals for wear and tear. Replace them if they become damaged or discolored to maintain a watertight enclosure.
- Roller and Track Maintenance: Keep the top and bottom tracks free of debris and soap scum to ensure smooth door operation. You may apply a silicone-based lubricant to the rollers if they begin to stick.
