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

you dont want a detergent you want a anti fungal stuff which inhibits growth of moss and stuff but to be honest you would be better trying to get a regular clean once a year im not convinced the sprays do their job!!

Thanks for the info i'll try and convince them that a once a year clean is the best option

Best product i have seen was on some steps at Leicester racecourse,
steps where p/washed then 1/2 were treated with a product called greenBgone,
2 years later 1/2 treated has no green on them,
available from  here   http://www.worldofclean.co.uk/index.php?productID=446
sorry just checked, now called Stayclean
