Sodium Hypochlorite 5L Patio Cleaner | High Strength, Swimming Pool Liquid Chlorine 5L

Sodium Hypochlorite by far the best path cleaner that I have ever used - and it gives a far better and longer lasting treatment than any other preparation I have tried over the last 50 or so years!I sometimes use a jet washer to clean my Indian stone, cobbles and other path and patio surfaces, but it does not clean as well or last for as long before it need's doing again.Once the technique of finding the right strength of solution is found it is an easy task to clean any stonework (including walls!).I always water it down a little before applying it over a dampened area with a watering can and brushing it over with a stiff brush to agitate it .I also find it easier and less time consuming than jet washing, so for me it is the best way to keep my outside hard surfaces looking clean and tidy for longer.

Perfect product which I have started using every year now. It gets rid of the stains created throughout winter and is easy to use. I wet the patio then sprayed on at a ratio of 5/1. Left for 45 minutes or so and went over with a hard brush then washed off with a hose. Great results. Some stubborn stains need a pure solution but all in all great product and well worth doing.

My paving slabs have been green, dirty and full of black spot for years .I jet wash them every year but they soon get dirty. I rolled the solution on and I could not believe that it started to work right away. Dirt, moss and black spot disappeared. Less work and l saved loads of water not using the jet wash. I have a lot of slabs and brick paving. Just ordered my third pack of two as I am slowly removing old brick sealant. Brilliant and a cheap alternative to patio cleaner and better.

Good.product although foaming types are easier to.see where you have used the product . You.may need 2 or three tries before black spot comes.off somorder more than you think. Overall my.drive.looks very good now

I used it my block paving and it’s excellent. Cleans brilliantly and kills the weeds with a couple of hours. Highly recommend.
