SIKA Everbuild SALT5 Salt Away Treatment Remover of Salt and Efflorescence From Bricks, Stone and Concrete, 5 Litre

I am SUPER pleased with this product. After months waiting for workmen to clean runoff from porous asphalt drive onto my block paving and an attempt by them at power hose cleaning and the use of two chemicals (with hardly any effect) I bought this Sika remover and did it myself. I am 82 and in ill health but following instructions it was not difficult .

Applied this, let it soak and it did nothing, nil, nought, zero, no way hose, you get the picture ? Brushed till my arms fell off. Did it all again. Legs fell off. Useless.

Bought due to patio having salt deposits all over it, apparently the extreme weather conditions this year have effected a lot of paving during manufacture, this is £10 cheaper than the local builders Merchant, given 4 stars as have used but waiting for final result, pavers have lightened and a lot of salt came out but after the heavy rains it's just watch and see, hopefully it's worked- Hint - easier to brush on as a spray leaves spot mark's, and it leaves a stick residue so be careful to remove any plant pots etc, wear protective gloves and ensure arms and legs are covered and wear wellies.

I have read quite a few negative reviews, but thought I would try it - I paid £13 odd for 5 litres, so not expensive.I tried it on the smallest bit of slate first, to make sure it wouldn’t damage it as some people have said their paving got stained. The results speak for themselves- look at my before and after pics - years of calcified water deposits were removed from a second hand water feature - it was a bit of a labour of love and the build up needed a few goes, but I did it with one 5 litre container. This is my method: I painted it on the first time, then pressure washed off after a few hours- removed some but not all of the salts, so repeated a few times over the week Smaller bits of slate were submerged in a bucket. Finally, with the awkward bits, I soaked kitchen roll in salt away, and packed it around and into the awkward areas - covered it in plastic bags to keep it moist over night, and again pressure washed off, and that worked a treat - I maybe should have done that earlier. This product is made of Citric acid and water according to the packaging - NOT ammonia as stated in the listing. Whatever its made from, I recommend it, but you do need to put in a bit of time and effort.

This salt‑stain remover works only to a point. On newer stains it helps loosen the white residue, but unfortunately older, deep salt marks on bricks or concrete don’t come off — even when using the product undiluted. I tried multiple applications and the result was the same. It’s fine for light, recent buildup, but don’t expect it to clean long‑standing stains
