I hate trying to keep our old porcelain tub and sinks clean.  This came as a suggestion from my sister Erin.  Thank you, Thank you!!! Bar Keepers Friend 
is by far the best thing I've found to clean any porcelain surface.
Other uses for this product:
Can be used on stainless steal, plastic dishes, stove tops, tea or coffee cups! It also removes rust and discoloration from car bumpers and automobile chrome.
Hope this is a helpful cleaning tip! I love this product and I hope you'll give it a try.

s the end result.  However, picture in you mind an old, brown door covered in dust.  I knew right away exactly what to do with it.
