Dominion Products
I use products from Dominion, for the past year, and have achieved from good to great success. I use both cold and hot water cleaning systems and hot water is the way to go when cleaning concrete surfaces. It not only cuts your cleaning time it also cuts the amount of cleaning product you use in half. Had I known this I would have changed to hot water three years ago. As for DR-60 my experience is it cleans as the advertisement would suggest, if it is fresh stains. It becomes too pricey if you have to reapply to almost remove old stains. As mentioned before it must be applied to a dry surface, trust me you might as well dump the product down the drain if the surface is wet. Don't try to use it as a spot cleaner, to possibly to save money or to give a lower quote, you will clean the spot but once dry you will end up with a nice bright, almost white, spot in the middle of a contere slab. If you are fortunate to land a contract where you clean every 6 to 8 weeks DR-60 will make the surface look new after a few visits. Then once you get the surface clean you might be able to sell sealing the surface thus reducing the amount of product you use.
