Floor adhesive removal

[AMS1]

Hello

A few years ago the council converted my pensioner father's bathroom into a wet room as he could no longer manage climbing in and out of the bath.

The white capping strip (I'm not sure if that is what it is ... a horizontal plastic strip that separates the curved flooring from the ceramic bathroom tiles?) is very discoloured in places with a yellowy brown stain. I'm wondering if this is the glue that the council used to glue down the floor. There's also a similar yellow brown stain on the woodwork at the bottom of the door frame, and on one of the white ceramic tiles.

I've tried all sorts to clean these stains but nothing seems to work. Is there a specialist product that might do the trick? The stain on the door frame I'm not too bothered about as we can sand it down and then repaint the whole frame, but I'm more concerned about the marks on this white strip.

OK - not the answer you want, but......

council installed wet rooms are notoriously done on a shoestring.
their contractors get so little money that loads of corners get cut

....result - they quickly start leaking

if they think you have done anything in there that allows them to blame you for the leak then you will get a huge bill

SO PLEASE LIVE WITH IT!
