This post has great tips for how to clean a porcelain sink with baking soda, vinegar, and Bar Keepers Friend. Learn how to fix a stained white sink easily and clean the drain effectively!
First thing's first – wet your whole sink with water, using a sprayer if you have one. Then, I add my absolute favorite secret weapon to getting all of the gunk off and making the white porcelain shine – baking soda. Then, use a spray bottle of half white vinegar/half water and wet down all of the baking soda. This will fizz a little, which seems to help break up all of the dirt and grime. Allow this to set for 5 minutes or so.
After the baking soda and vinegar mixture has set, use a melamine sponge to scrub down everything, including the drains. Don't be afraid to give it a little elbow grease!
Just sprinkle a little Bar Keepers Friend on your scratches or rust stains around the sink drain and really rub it in with circular motions with your melamine sponge. The scuff marks and discoloration should come out really easily.
After everything's looking good, I like to wipe all of the porcelain surfaces down with a dry dish towel to finish everything up. This makes sure there's no cleaner residue or hard water stains left.
