using the drain cleaner.
After using the drain cleaner, check if all tubes of the drain system are

Clean the drain cleaner and the attachments with water and mild

chemicals for cleaning.
Store the drain cleaner out of reach of children. Store it in a dry place
that is protected from dust, dirt and extreme temperatures.
