So after many hours of scrubbing I finally shifted the residue.
I used the solution Lithofin Wax Off Wax & Oil Remover
Here's what I did, I hope this helps someone too (but proceed with caution, I'm certain my approach is not industry standard, haha).
1. Cleaned the floor to prepare for the solution (lots of cleaning!)
2. Did a test in the corner of the room and saw how easily it shifted paint
3. Cleaned tiles that weren't so bad and watched in awe as they came up like new
4. Proceeded to tackle the bigger stain... not so easy
5. Applied a small amount and left for 5 minutes
6. Scrubbed like a crazy man for 15 minutes with a very hard stiff brush
7. Repeated this processed, increasing both the time and quantity of solution
8. Took a day off to rest (haha)
9. Came back engaged 'crazy-cleaning-mode' and scrubbed again with some solution
10. Dried the tiles and then applied viakal limescale remover, letting it sitting for about five minutes and then gently agitating with the stiff brush
11. Repeated this process
12. With a 5 in 1 decorator's tool gently scraped the final bits of muck and scale from the tile
13. Applied yet another solution
All in all I spent about 4-5 hours and about 600ml of Linthofin solution.
I now need to seal the tiles with stain stop and then apply some grout reviver.
Can anyone recommend a good grout reviver for the floor tiles? I used the pen, which is terrible on the walls, also used 'Forever white grout reviver' with some impressive results on the walls, but not so happy with floor.
