I am not at all proud of its filthy, and dingy state, but because I have banished all cleaning products from our home that have the slightest possibility of being toxic, I have to confess that it generally stays this way.
In a recent attempt to expand my repertoire of natural cleaning products beyond just baking soda, and white vinegar, I have been reading Green Up Your Cleanup, by Jill Potvin Schoff. It offers a multitude of green cleaning solutions for any number of filthy situations, including dingy shower doors just like mine.
As per the instructions in the book for "Baking Soda Scrub", I mixed castille soap with baking soda until it became a pasty consistency. You can use the non petroleum based dish soap instead if you don't have any castille soap.
This is what it looked like after mixing.
I then spread it over the test area of the shower door like this,
The instructions said to leave it on for longer that 15 minutes for "Heavy duty jobs" which this most certainly was.
Well over half an hour later, after Emily had thrown the biggest tantrum of her life and I had forgotten all about it, I returned, sprayed off the paste with white vinegar, and rinsed with water per the instructions.
This is the final result.
I am seriously impressed! It is obviously not perfectly clean, but it's pretty darn clean, cleaner than it's been since well before the chemical ban at least.
