Sodium Hypochlorite 14-15% 5L, Patio Cleaner | High Strength, Swimming Pool Chlorine

Strong industrial strength bleach hard to buy anywhere but on-line & this cleans the patio better than anything else I've ever used.Just don't let the run off get on any lawn or plants.

I had rather a lot of white spots on my patio, so I tried this. Yes, it cleaned the tiles to nigh-on perfection, but the white spots remained, however; what I did notice that after a couple of sprays (3 max) and then leaving each spray for 30-60 mins, it becomes considerably easy to brush the white spots away.To make sure it was the sodium hypochlorite that was helping I tried brushing away an untreated spot and that was nigh on impossible, so yes; if you have troublesome white/lime green spots you may find this an advantage.Update 08/05/24 (or 05/08/24 for our American cousins). Whilst my back garden had white spots (once upon a time) I noticed even more troublesome black spots in the front garden. They do eventually disappear too, but it'll take 3, maybe 4 attempts to finally clear them... completely... and that's without scrubbing at all (50/50 strength).

Saw a neighbour using this product so bought it myself. Delivery expedient, used product to clean o/s walls. Very effective.

I thought would smell more than bleach, but the smell does linger on. Good stuff, used to clean wetroom tiles and black spot on the patio. Do wear gloves and open windows whilst using. Happy to buy again, I think this works out just as cheap as a well known domestic bleach (in blue bottles), considering it should be 7 to 15 times stronger

Arrived on time

Excellent product, used 3-1 and it cleaned my brickwork to look like new, will be buying more

Very good

Cleaned my path and window ledges to like new. FANTASTIC product. Would have been five stars but the product was shipped with a loose cap, leaked all over. Don’t get on clothes etc or it will bleach then. Applied with a garden sprayer. Well recommend.
