We've all come across these problems some time or another.
Most users looking into this online for the best ways to remove this obstacle may be using solutions such as lemon juice, baking soda, and laundry detergent drying cloths, just to name a few.
In our experience here at LA Maid Pros, the all time best way to get the job done is by using 2 single products combined. CLR + Magic Erasers.
You will need a pair of gloves to accomplish this task as you will most definitely get a chemical burn if you do not use these.
After putting on your set of gloves, rather than wetting the Magic Erasers as described on the instruction box, you will want to drench the magic eraser with CLR. From there, like the product says.. its magic!
You will want to start one section at a time, wiping the magic eraser sponge across your glass window with the applied CLR solution. After completing each section you will want to wipe off the solution with a clean cloth.
Finally, after making through each section on the shower glass windows, use your favorite glass cleaning product to give it a once over, and just like that, you're glass doors will look sparkling new!
