Grout Magic Primer and Cleaner - Increases Porosity of Existing Grout for Correct Adhesion and Penetration of Sealer - 500 ml

Great for cleaning old grout to prepare for the grout restorer. Wear good quality rubber gloves and a quality face mask and open doors and windows. I used this on my floor tiles so had to lean over it to scrub and it really does take your breath away and stinks the whole house out. Can be used on other stained materials like gravestones etc Once done rince well with water and allow to fully dry. Great product for the price

Watched an English you tube clip how to paint my grout and this item alone with the paint of my choice worked wonders . Total revamp of my bathroom and a very cheap Price .

This product is totally unnecessary & totally toxic; using it is incredibly dangerous & the warnings alone made me realise it would unwise to try. I used the grout magic absolutely fine with just simple sugar soap cleaner on grout & so this product is unnecessary. Sadly the return of the unused product was far too difficult (printing multiple labels; expensive postage). Save your money & do not buy!

I have tried several ways of cleaning the kitchen floor grouting over the years. Most methods have been labour intensive with minimal results. My first attempt with this product removed a significant amount of scum. I scrubbed the product after three minutes with a heavy duty scrubbing brush. You could see the dirt coming away which was very satisfying. After a couple more attempts on the stubborn areas the overall result has been quite impressive. There are sections that are a little darker but I think that depends on how even the original grout was. I’m usually quite cynical about these products but this one is worth a try. I don’t feel the need to go over with the whitening product as for me the results are good enough.

Bought this along with grout magic paint it done such a good job cleaning the grout I haven’t used the paint yet. I have black tiles and black grout in the shower room, this cleaned all the limescale from the grout with ease. Very easy to use but do read the instructions, will buy again.

Very good but be careful when you are scrubbing the floor as it sprayed up on my chrome table legs and has marked them. My fault for not covering them!

I've read lotts of the reviews on this item , this is the cleaning solution and it's normally paired with the paint magic. Maybe it's just me , but I found it hard work and useless. Paint rubs off , I've cleaned grout afew times and put paint on . Some stays on and some comes off . In the end I used matt black paint on it and it worked like a dream , excess on tile wiped off. So much easier and cheaper. And don't believe ytube videos on this product, looks so easy. Believe me it's hard work and messy 😪

We decided to paint out light grout in the kitchen brown, but needed to clean the grout first. Did put on glasses and mask as quite strong. Used a tooth brush and cloth. Gets the dirt and stains out really easily with not that much effort.
