We get ours from a farm supply shop it’s dairy hypochlorite 10% strength and £12 for 20 ltr , we dilute it 4-1 . 

Wet the area down with a hose pipe first then apply hypo mix with a sprayer or watering can leave for 20-40 muinits then pressure wash and rinse down.  Hope this helps .

Mix it 4or 5 ltr of water to 1 ltr of hypo , before applying  it soak all the plants in the area with garden hose apply hypo mix to path yoh might need two or three applications leaving it 10-20 muinits between applications just keep it wet by applying a bit hear and there , between applications of hypo wet the plants down again they only need a mist spray to keep the hypo off them , I have never killed any plants in 15 years of softwashing you might catch the edge of the lawn if it buts up to the path , but it won’t do much harm .

5.3 litres of hypo and top up to 20l with water is a 4% mix which will be perfect.

Soak the plants thoroughly with a hose so they have a good drink and don't soak up the hypo and then rinse them off again afterwards.
