Non-abrasive and neutral toilet cleanser: Removes yellowish and/or blackish contamination from the toilet bowl.

• †† Ceramic parts

NOTE:

• AQUA CERAMIC is a material that has a high hydrophilic nature and contaminations attached to the toilet bowl tend to be easily removed. However, cleaning is still necessary. If contaminations remain on the pottery surface or feces are fatty, it may not be easy to remove them. Clean the toilet on a periodic basis. To fully utilize the effect of AQUA CERAMIC, do not use the following cleaners and tools.
  • Strong alkali/acidic cleansers
  • Abrasive cleansers
  • Water-shedding or antifouling cleansers, or surface coating agent
  • Cleaning tools that damage the material surface, such as metallic or abrasive brushes
    

• Set the [AUTO FLUSH] and [AUTO OPEN/CLOSE] to [OFF] when cleaning the toilet to avoid misdetection.
