Sika Brick & Patio Cleaner High Strength Brick and Patio Cleaner, 5 Litre

Excellent gers the bricks brand new again. Would recommend. The smell isn't great but once washed of the smell is gone .would definitely recommend

Used to clean driveway in preparation for sealing. I haven't used any chemicals before always just jet washed so I am unable to comment on how effective it was especially as accumulated tire dirt was slightly still visible in high use areas. However, I would still use as its environmentally friendly and water based. Found another use for it .......😳 I award it 5-starts however, for getting rid of limescale build-up in my toilet! I cannot even describe how extremely happy I am to see the bottom of a clean toilet bowl after years of trying every hack imaginable all of which failed until I read another review and thought I'd give Sika a try ....wow!

Well my hubby said it’s excellent so it must be.

Not strong enough

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

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

Does not work very well pretty useless to be honest. Used at strongest ratio very ineffective, white ginger was better and that was diluted. Wont buy again

Works great for my purpose - which may be different to others.' I need it to clean (dissolve) adhesive from the backs of porcelain tiles so I can reuse them. For that it works well for 2-3 tiles (60x60cm). After that the active ingredient, hydrochloric acid, is neutralised too much by the base of the adhesive to do more. That's not the fault of the product by any means. UK law restricts Sika from increasing the HCl concentration; that is, making the cleaner any stronger without requiring the customer to obtain a special Government licence. You probably wouldn't want it any stronger to clean a patio, anyway, as you'd risk killing lawn and plants nearby.
