Hi all,
I'm in the pipeline of quoting to clean up a school yard. The yard has york stone and in the winter it gets very slippy due to it hardly ever getting any sunlight. The school in the past has just pressure washed the yard. But this time they want to push the boat out and treat it with some sort of detergent before pressure washing it. Now can anyone on here reccomend any sort of detergent tha would sort this problem out ?.
thanks in advance
