The answer to 'how to maintain sink' is to regularly clean and maintain your sink to prevent clogs, odors, and other issues. This includes cleaning the sink basin, drain, and faucet, as well as addressing any minor repairs or leaks promptly.
Start by wiping down the sink basin with a mild soap and water solution, or a dedicated sink cleaner. Avoid abrasive cleaners that can scratch the surface. Next, use a drain brush or plumber's snake to clear any debris or buildup in the drain. For tough clogs, you may need to use a plunger or chemical drain cleaner. Regularly clean the faucet and surrounding areas to prevent mineral buildup. Finally, inspect the sink for any leaks or damage and address them right away to prevent further issues.
