Sika Brick & Patio Cleaner 5Lt

I don't know about cleaning brickwork or patios, but its a great drain cleaner/unblocked. Cheaper than the "off the shelf" drain cleaners/unblocked. Just pour down the sink/bath drain and leave for 20-30 minutes, rinse well with water and it should be free flowing again. If not, rinse and repeat

The product is fine , however it is not the manufacturer’s product that I ordered and not as effective as the Sika brick and patio cleaner which I ordered , and utilised previously.

This works brilliantly it’s perfectly priced. I use it for my patio and it makes it look like new I also use it for cleaning my toilet which makes it gleaming. All you have to do is empty the water out of the bowl completely and then pour it this cleaner up to the waterline and leave for an hour if you leave it longer it will work better for more stubborn build up of limescale make sure to wear rubber gloves and use a hard bristle brush to coat all areas and leave 20 minutes for that to work in after the 20 minutes just give it a quick scrub with the brush then flush it

Not strong enough

This stuff cuts through patio grime like it owes it money. Moss, algae, general filth – gone after a soak and a scrub. It’s not the kind of product you want to sniff for fun, but it works fast and rinses off cleanly. I used it on a wall too, and it came up brighter than I expected. Just don’t wear your good shoes while using it.
