You can make your own, ultra-effective shower enclosure cleaning solution inexpensively. Just mix together baking soda with water to form a thick paste.
How much you need to make will depend on the size of your shower space, but half a cup of baking soda should suffice as a starting point.
Then, dip a non-abrasive sponge into the solution and use it to scrub your glass shower doors clean. Once you’re satisfied the enclosure looks clean, you can use vinegar and/or fresh water to rinse the glass surface down.
