Hi, If anyone can assist I'd be grateful. I have Victorian tiles which I purchased reclaimed to Finnish a job. when they arrived they seem to have a pattern stain lime that of underlay. I can't wash it off. I have tried many different methods. I did try baking soda mixed with washing up liquid and a drop of water - this did with effort remove the stain. but it seems this method is taking a slight layer off the top of the time. I will try enhance the time with perhaps linseed oil ?
Anyone come across this staining and perhaps recommend the right way for its removal.
Many thanks
