Lithofin Intensive Cleaner

[On one]

I've got job where the original tiler on a job has been kicked off for among many things leaving some horrendous grout haze on the 600x600 porcelain floor tiles(1 wash over and left it by the look of it)

I have had success in cleaning off the kitchen floor with diluted Intensive Cleaner 1-4water,but cleaning the utility floor has not been so successful.
If I went 1-1 dilution on Monday and this didn't clean the haze up what would be the next option @Lithofin BOB (A very expensive kitchen has already been fitted on the floor as well!)

Try and test the intensive on one tile at 1-1 or neat, if there's a spare tile on site test it on this first -10-15 mins application , white pad -stiff brush
This will break the polymer binder of the grout, if it still remains you can try an acidic product,this will try to break the cementisiouse part- we have cement residue remover, it may need a combination of the two one after each other- poss several times- if it remains ( are the tiles polished or textured?) if polished ,you could try one of the magic sponges

Fraid I can't go down the spare tile route as the tiles are already fitted.
The tiles are only slightly textured.........magic sponge tho ?????

U could just get the big guns out and brutalize it with brick acid if nothing works I've cleaned a load of trowels with the stuff recently it's good stuff

You may get Clean tiles Kyle ,but you might have to pay for new trims fridge,light,sockets, tv if stainless
Brick acid is generally hydrochloric acid , the vapour is the bit to watch for, fine external for tools and bricks

Even just carrying tubs of hydrochloric acid ( for swimming pools) around in my old van the mesh bulkhead went rusty!
I just pick them up when I need them now and have one at each client instead of taking it around with me.
