Cleaning dried Bal grout off of Topps Stratum Anthracite tiles

[tired]

I Have a problem I hope you will be able to help me with!

I have tiled my new walk-in shower walls with Topps Stratum Tiles in a dark slate grey colour, but some one helped with the grouting
and didn't clean it off before it set. I have since bought topps extra strength grout cleaner but although it is helping a little it is still
not off and all the tiles have a white coating of powder over them........................help what do you suggest???

Tired:yikes:

Lithofin cement away . But test first for results.

Cover anything up that can get damaged.

Dilute first and increase in strength till it works.

Wear appropriate ppe.

Welcome to Tilers Forum.
Although I cannot advise you to do this and every care should be taken to follow the instructions on the container, I would consider the brick cleaner from BQ or similar! It's contains up to 15% acid and so the 'warning' calls should be heeded. Well ventilate the room as fumes can taint chrome, use plenty of water to wash off and DO A TEST AREA FIRST OUT OF SIGHT. Please take care but it does work for missed built up areas of grout.

I was gunna suggest brick acid TJ.. but thought i better not as some mightbe shocked... but yes it is the cheapest residue remove about but IMO for pro use..

those tiles are a nightmare I am using them on a new build job at the moment we had a similar problem we used brick acid and a scrubbing brush and it got into the crevices of the tile really well , it took 2 attempts to get them perfect but they will come clean

You are right Dave - I was hesitant to suggest the brick cleaner in open forum and although I've used it for years, it can have its problems. Many years ago we had to replace the chrome coated plastic shower attachments that were etched by the acid!
Not really for the DIY but it works with care!

Expert Tiling Tips from Toby

"These tiles are designed to be butted up together for minimal grout lines - apply grout with the finger to fill the odd spaces which may naturally occur. If you’re using in a wet area, we recommend waterproof matting before the product is affixed."

Yep......you read it......to coin a Richard Littlejohn phrase........you couldnt make it up
