I am also looking at other options to remove Lithofin Slate Seal.
Up to very recently, I WAS the West Yorkshire Tile Doctor. I noticed there was also another Tile Doctor on here who mentioned Aqua Mix products. I bought the Aqua Mix seal and coating remover and am due to try it on a slate floor soon.
I tried to contact the other Tile Docter via a web site in Surrey. Sadly, he didnt bother replying.
Jeremy Taylor claims he "stumbled" across my thread on the Surrey website and told me to remove the thread as it didnt make Tile Doctors product "Remove & Go" look good.
Thats because it doesnt work Jeremy!!
In my opinion and experiance with the product, it doesnt remove slate seal.
As I have now been given the elbow by Tile Doctor, I am free to talk as much as I want about the products.
So, in my opinion, you could do a lot better than trying Remove & Go to remove slate seal, I have tried it numerous times with no results.
I have to admit to taking an interest in the water based product that has been mentioned on this thread. Water based products in peoples houses has to be a bonus.
