Deep Cleaning the Kitchen Sink
The kitchen sink handles more daily work than almost any other surface in the home — food prep, dishwashing, and constant water exposure create a surface that needs more than a daily wipe to stay truly clean. The specific cleaning approach depends on the sink material.
Stainless Steel Sinks
Stainless steel's greatest enemy is water spot and calcium scale from Ontario municipal water. Daily: rinse and dry with a cloth to prevent water spots — letting water sit and evaporate leaves mineral deposits that accumulate into visible staining. For deep cleaning: scrub with baking soda paste (the mild abrasive works without scratching) in the direction of the grain. For heavy scale: white vinegar applied and left 10 minutes before scrubbing dissolves calcium deposits. Polish with a few drops of mineral oil on a cloth to restore the luster and slow future water spotting. Never use steel wool or harsh abrasive pads — they scratch the surface and make future staining worse.
Composite and Granite Sinks
Composite sinks (typically quartz or granite compound materials) are more susceptible to staining from coffee, tea, and red wine than stainless — blot spills immediately. Clean with a non-abrasive cleaner (Bar Keepers Friend is effective and won't damage the composite). White spots from hard water: a paste of baking soda and white vinegar, left 15 minutes before rinsing.
The Drain and Garbage Disposal
Monthly: pour boiling water down the drain, followed by a cup of baking soda, followed by a cup of white vinegar. The reaction clears buildup in the drain. For garbage disposals: grind ice cubes monthly to clean the grinding mechanism, then grind a quartered lemon to deodorize. Never pour grease down the drain — it solidifies in the pipes and is the leading cause of Ontario home drain blockages.
