Bio-Clean Hard Water Stain Remover

Depending on the nature of the deposit this works really well. One client of mine tends to get silicate deposites and this wont touch them. Another gets calcium and magnesium deposits on windows next to their flower beds and this does great. I prefer this when I can use it because of its non toxic properties.

Works great!

Started with my own shower door to test it out. Was NOT disappointed. Will be ordering larger quantities in the future.
