Buy and install a little strainer to place over the drain for trapping food, hair, soap, etc. Clean the strainer regularly.
Collect cooking fats in a container such as a can and dispose of it in the garbage rather than pouring fats down the drain. Fats can solidify in cold pipes and create clogs.
Pour a kettle of boiling water down the kitchen drain weekly to melt fat that might be building up.
Pour a mixture of a handful of baking soda with 1/2 a cup of vinegar down the kitchen drain weekly. This will break down fat and keep the drain smelling fresh too.
Use an enzyme drain cleaner regularly.
