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

I had to apply this cleaner multiple times and neat on these white efflorescence stained bricks.. I wasn’t expecting it to work as this brickwork has been stained for decades but I was pleasantly surprised with the results so far. On the very heavy white efflorescence it really fizzed and then with scrubbing, rinsing and repeating the process I’m slowly getting results. Before and after pics attached

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!

Does exactly what it's supposed to and at a reasonable price

very good cleaned all the surfaces I needed to do

Not strong enough

Clear instructions, great results. Dress appropriately - when you see how clean the bricks come, you know this is strong stuff that really works!

Utter rubbish. Don't waste your money, can't remove anything

It works but takes longer than it should, Better used neat on a wetted surface I found
