What are the maintenance requirements for walk-in bathtubs?

Clean a walk-in bathtub with the products and frequency specified by its manufacturer. Rinse away residue, keep the drain clear and inspect the door seal for debris or damage. Jetted models may need a separate flushing or purge routine. Do not apply lubricants, abrasive cleaners or chemical treatments unless the instructions allow them. Compare service access and warranty coverage when buying; a self-cleaning feature does not eliminate routine maintenance.
