Tips
Borax may be substituted for baking soda.
Baking soda is helpful for keeping shower and sink drains clog-free organically. Scoop any leftover baking soda mix into the drain, let it sit for a few minutes and run hot water into the drain.
Warning
White vinegar may scratch ceramic tile. Use it cautiously, or substitute warm water for vinegar when scouring tiles with baking soda or borax.
