I thought it would be a good idea to put a little caustic soda down the

Would be a big job to get to the trap. I've tried a plunger, and tried
neutralising with spirits of salts (NaOH + HCl H2O + NaCL, ie salt
and water). -still no joy. The drain hole has a white disk a little
below the opening which prevents direct poking.
Any ideas?

An acid such as brick cleaner. Not too much.

Spirits of salt *is* brick acid. Or hydrochloric acid. Doo keep up.
