How To Clean A Granite Composite Sink

I live in an area where the water is hard and calcium builds up and causes white rings/stains on my sink.  Since my sink is a dark grey granite composite these marks are very noticeable.  Here is what my sink looked like before the cleaning.

008I had tried everything even vinegar but that left a film.  I researched on the internet and when I found out the “secret” I was amazed that it could be that simple and inexpensive, not to mention without harsh chemicals.

Here is what I use to clean my sink.  Can you tell what the “secret” item is?

009It is not the Mr. Clean Magic Eraser, all though this is an amazing device, it is the baby oil!

So here is how I clean the sink:

Step 1 – clean the sink with Mr. Clean Magic Eraser.  Make sure to get all of the stuck food items, etc. off and rinse the sink well.

011Step 2 – spray Windex on your faucet fixtures and whip them down with a clean cloth.  I use old washcloths as they are very absorbent and don’t leave fuzzes.  Once the fixtures are clean, use the same cloth to dry out the sinks.  Make sure they are very dry.

013Now you may think you are done, however, once the sink sits for a while those nasty white marks appear again.  So here is where the magic happens.

Step 3 – Pour a little baby oil on a clean dry cloth – about the size of a quarter.  Use a clean cloth – not the same one you used to dry your sink as water and oil don’t mix and you won’t get the same effect.  Rub the sink down with the baby oil rag.  Don’t be afraid to use a little elbow grease here.  I typically will wipe down the divider of the sink, then the sides of the left sink.  I then apply another quarter size of baby oil and wipe the sink bottom and the sides and sink bottom of the right sink.  That is all you need as you don’t want it to be to oily.  Here is the finished product:



My sink will usually stay this way for about 2 – 3 months.  Then I will go through this process again.  In between treatments, I will usually give my sink a wipe down with my dishtowel after the evening dishes have been cleaned up and put in the dishwasher.  This way my sink is dry and clean and I put out fresh dishtowels for the next day.

I hope you have found this information useful.  To clean my granite counter-tops I found this product at Target. I works wonders and it often on sale for a good price.

    An oil based stainless steel cleaner simply sprayed onto a clean sink and then rubbed in with a dry dish towel is the simplest method I’ve found.

    I want to say thank you from the bottom of my heart. I loved my sink when I first got it then came the soap scum then I hated my sink. I have tried and bought everything. And this is so simple and safe. Again thank you again.
