Multi Surface Algae Remover

This arrived earlier than expected and as it was a dry day I used it straight away on my York stone flag paving that was very slippy with algae after all the damp weather. It seemed to start working straight away on some of the less green areas so impressed, hopefully it will complete the job as stated in a few days.It's a small bottle {1litre} but it will do a second round in the Spring. I managed to do a small patio and front garden area and stone walls with one 1/2 litre. The moss between the paving has started to die back after only a few hours too! Great stuff and safe after it is dry for animals....important as I have a visiting squirrel who's preparing for Winter!! :)
