Cleaning Limestone patio? Best product?

Hi Folks,

The spring clean and garden cleanup have started in earnest round mine. We have a limestone patio that has grown a huge crop of algae and staining over the winter along with some black spotting.

My usual course of action is to use Mossgo patio cleaner. 2.5ltrs diluted 1-1 and sprayed on. Left 20mins and then brushed before I pressure wash it.

This year the result from the Mossgo hasn't been great, and I don't want to get too trigger happy with the pressure washer.

I want to give it the best clean I can before I lay down a sealing coat.

Any suggestions on a products that I can use will be very much appreciated.

I picked up some Gold Assure Chloro-clean at my local Co-Op and in the main, its done an excellent job. There are a couple of lingering spots of Black Lichen but, I'll get those sorted with some more targeted and less diluted Chloro-clean.

Long story short, the €17 spent on concentrated bleach was by far the best money laid out versus the other patio cleaning products tried.

You need Path Clear from Kilco. You can get it from any Farm and Home store place. 25 litres is 30 quid, and you mix it with water 10:1. My patios get very heavy blackspot that power washing alone won't shift, so what I do is a general power wash and then pour the Path Clear mixture over the affected area. I can guarantee you within 10 minutes the spots will disappear, it's actually mad to watch. I'd post a link but I'm not here long enough, sorry.

I would worry about the damage to garden plants from run off water from these products 😐️
