No tried that it took the morter out but nothing else

Hi footprints, no I am quite sure it's not, it was there when I took the top layer off with a scraper, then alot of hard work mainly with stainless steel scourers.

I Cleaned some tyrolean render off some engineering bricks and its left a residue on the brick, I have used brick acid, thinners, turps, wire brushes and nothing moves the residue, has anyone had any experiences like this.

Hi MPG I see you had problems with engineering brick years go did you sort it? I had tyrolean render on my engineering bricks, had a nightmare getting it off, now left with a white residue on the brick.
