Bio-Clean Hard Water Stain Remover

Outstanding Performance

35 years with my window washing business and this is the best mineral deposit remover that I have ever used. Also, has a really nice scent that my customers and me like very much. Highly Recommend

It worked very good, have to do it a couple more times to get it spotless

Bio-Clean

I use this product not just for hard water stain removal. I use it everyday during the regular window cleaning. Mixed with my window cleaning solutions, it creates a water barrier on the glass that repells water.
