I have recently seen the sulphuric acid to clear blocked drains.
Having googled around, it seems I should not mix the 2. I am trying
the caustic soda today followed by boiling water and detergent.

If that fails, how long should I wait before i move on to the acid?

Theres also the option of a flexible wire rod. Screwfix sell them for
about £15 or so.

Could well be worth a go. You could "borrow" some "curtain
wire", or use a bicycle cable, just for an experiment....
