Lithofin KUKÜ Cement Veil Remover Extra 1 Litre

I had heavy cement stains on my porcelain patio tiles and nothing would remove it until I found this product. Instructions say to dilute it for use, but I found that the only way it would remove the stains was using it undiluted. I was worried that this would damage the porcelain tiles, but not only did it remove the stains it did not mark the tiles. Admittedly I had to use a strong bristle circular brush in my drill to scrub the tiles, but as I said previously nothing else nothing else worked. I need to order more due to use undiluted to finish the task.

does what it says on the tin and then some, small issue was that I was unable to open the screwtop which had a safety feature, so I had to punch a hole in the lid

Does what it says

This product was quite expensive and didnt remove efflorescence from my brickwork as promised.In the end, I purchased the far less expensive Spirits of Salts and this worked very well for me.

Does not work on limestone.... Loss of money
