How to clean shower doors and windows without having to replace them.
The best way I have found on how to clean shower doors, from personal trial and error and recommendations from cleaning professionals, is to take it sections at a time.
Do not try and clean the entire shower in one swipe. Remember some of these minerals have been on the glass and hard surfaces for months, if not years. I like to use somewhat of an abrasive pad, like a 3mil pad.
How to Clean Shower Doors Effectively:
I use a circular motion and work in sections when scrubbing. I only use a small amount of water when scrubbing. Most people seem to use water with their product, however this dilutes the product. The Bring It On Cleaner is used by professional glass cleaning companies for some of the most difficult jobs.
I let the Bring It On Cleaner sit on the shower for a few minutes after scrubbing, ( this allow the oxygen bleach to pull out stains and help break the bond between the mineral and the surface.) Also, for tile and grout, this will help pull stains from your grout lines. Another great aspect about this product is that you can use it on a number of different surfaces. Tile and Grout, glass, windows, stone and brick, plastic furniture, even to remove stains.
Next, I use water and a rag to wipe down the shower.
Another way to remove hard water, mineral buildup, and water spots are these amazing Drill Brushes, by Bring It On Cleaner. They work fast and effective and have multiple uses around the house. Also check out this video of the Bring It On Drill Brushes in action. They clean tile and grout, sinks, tubs, counter tops, baseboard, couches, pots and pans, just to name a few.
