Products - Rob Parkers Best

After the builders had left my newly laid Indian sandstone a complete mess with cement ingrained into the stone I was at a loss as how to clean this given the general advice not to use brick acid. There seemed to be very few alternatives on the market until I came across this product. Having pressure washed it twice to no avail (prior to using the cleaner) I must admit I was a little sceptical that anything other than a really strong chemical based product would clean the stone. However after having applied two coats the stones have gone from a generic white powder colour due to the cement to having their natural colour restored. There are still small traces of cement but the results were amazing.
