Wash the lower chamber once a month with soapy dishwater.
In areas with hard water, calcium scale may build up on the faucet and chambers after prolonged use. To remove them, soak the affected areas in vinegar or a 50-50% mixture of vinegar and water for about 15 minutes. Wipe away the calcium scale with a ScotchBrite pad or soft brush, then wash with soapy dish water and rinse.
