I stupidly bought some self adhesive tiles from Home Bargains about 6 months ago, and covered my floor with them. As they were looking worse for wear, I've removed them today, and this is the state of the floor.
So far I've used floor cleaner, pink stuff, soap and have been scrubbing and steam mopping for the past 2 hours.
I've currently got a mixture of lemon juice and baking powder on it. Does anyone else have any other suggestions please?
