Maintenance and Care
Regular cleaning and proper care will help maintain the appearance and hygiene of your toilet seat.
- Cleaning: Clean the toilet seat regularly with a soft cloth, warm water, and a mild, non-abrasive soap.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, scouring pads, strong acids, alkalis, or organic solvents, as these can damage the polypropylene surface and finish.
- Drying: After cleaning, wipe the seat dry with a soft cloth to prevent water spots.
- Check Fittings: Periodically check the mounting bolts and hinges to ensure they remain tight. Retighten if necessary to prevent the seat from shifting.
Troubleshooting
Here are solutions to common issues you might encounter.
- Seat is Loose or Shifts:
Solution: The mounting bolts may have loosened over time. Carefully lift the seat to access the bolts and tighten them with an appropriate screwdriver or wrench. Do not overtighten. - Stains on Seat Surface:
Solution: For most stains, a mild soap and water solution should suffice. For more stubborn marks, use a non-abrasive bathroom cleaner specifically designed for plastic surfaces. Always test cleaners on an inconspicuous area first. - Seat Does Not Fit Properly:
Solution: Ensure the toilet seat is compatible with your toilet bowl model. This seat is designed for Armitage Shanks Contour 21 Splash 355mm high bowls. Refer to the technical drawing in the Setup section for dimensions.
