I am interested in trying your product, Masonry Cleaner 3427, to clean heavy soiling and water stains from interior flat concrete walls. The building, the New York Hall of Science in Queens, NY, is constructed of cast-in-place concrete with pre-cast concrete panels with inset cobalt art glass. Is this product safe to use on smooth-surfaced decorative glass? Is this product safe for interior use?

I unpacked the chemical samples Sunday and have not been able to use them until today. I want to test them on some really bad apartments I have coming up this week. I will take some before and after pictures and send them to you. I did however use some of the spot remover. I used it to remove some asphalt in the doorway. It has a pleasant smell and does not have that typical heavy chemical smell to it. This is a plus as I hate to come back over a spot and extract it to remove the nasty chemical smell. it did a really nice job of removing the asphalt from the carpet, in fact it dissolved it pretty nice.-Gary

The best compliment you can receive on your carpet cleaning and deodorizing job is to have the customer say, "This room smells so fresh!"..
