I have a slight tacies of mould in the grout of the vertical wall of my 
shower unit.

I have scrap[ed the old grout away. What is the best way of knocking out
any traces left?. Bleach only whitens but does not kill.

Have you tried "Dettox Anti-Bacterial Mould & Mildew Remover"? I have
found this product works exceptionally well. Just spray it on, and
within a few seconds you'll see it starting to work.

Be careful not to get any on your clothes, towels etc, because it'll
bleach them. The 'trigger spray' often leaks mind, but I understand
they have redesigned it now (?)

I second the above.

It's the ONLY product I have found that works on shower mats.
