HG Terracotta Cleaner Extra Strong, Product 87, Concentrated Cleaning for Removal of Grease, Polish, Protective Films & Ingrained Dirt, For All Types of Terra Cotta Floors - 1 Litre (194100106)

Seems to have worked very well

Use gloves, may need to use more than once to get best results. I had 3 goes to get desired result.

A last gasp chance at cleaning some filthy quarry tiles - 4 sqm - in our porch I followed the instructions,very easy to use. Because the tiles were so engrained, I used it neat with a scrubbing brush It worked beautifully - but it did only just do the 4sqm

Performed exactly as advertised

Used to clean old terracotta tiles found under carpets in the floods on 1/January/2025,they cleaned the tiles very well but I would follow the instructions carefully as leaving on too long could damage the finish on the tile,the cleaner removes ingrained grime so quite strong leaving the tiles clean and bright with negligible smell but I did have the doors open,the cleaner was good value for money as I now love the terracotta tiling on show,Highly Recommended.
