Kitchen Sink: How to Maintain and Prevent Problems

• Once a month, boil a few gallons of water and carefully pour it down the sink. Boiled water is significantly hotter than tap water and it will help dissolve soapy, greasy materials that are coating the walls of your pipes.
• Do not pour grease or fats down the drain.
• Do not wash coffee grounds down the sink. Throw them out.
• Use chemical cleaners sparingly, especially if you have metal pipes. Some chemical cleaners can cause metal pipes to corrode. We do not ever recommend using ANY chemical cleaners.
• Some mild sodium hydroxide or sodium nitrate cleaners may be somewhat effective if used no more than once every few months but we do not recommend any brand of chemical drain cleaner, ever!
• We think using a bacteriological and environmentally safe drain cleaner is the best option for drain maintenance.
