Kev,
Sorry if my comment upset u
but again seems over the top for one bath
...as most guys do not have Aqua mix sealing blah blah ..... handy.
Your comment
You need Aqua Mix Sealing & Coating Remover. We have also carried out dozens of refurbs mainly cubicles and hence its based on our experience
results similar with trade Upvc solvent cleaner (as you know these do vary considerably with suppliers- who stock various grades) or nail varnish remover very very cheap and easily obtainable for one bath seemed the easiest and simplest solution, I can assure you it has worked for us every time.
