3.Sanitize and Whiten the Caulk Line

While the solution sits in the sink, I like to do a bit extra. Grab some paper towels, dip them into the bleach water, and place them along the caulk line of the sink.

    If u have a septic tank, u should not use bleach in any of ur plumbing. It kills the bacteria necessary in the septic system to properly breakdown the waste. Use only products safe for septic systems!

      Use of bleach is not something I use in my sink. I clean it with a simple cleaner, never let it get so dirty I need bleach. And after use, I take my hand and sprinkle some running water around the sink to remove any debris. I also wipe down faucets, etc after I use it to brush teeth and wash face. That way it always looks clean. A separate towel is nearby to do that. When kids were home, they were trained to to the same, preparing the area for the next person's use.
