...and lime scale in the toilet bowl?
I asked my cleaner not to come during the covid times and she would have dealt with these problems.

Any good limescale remover should work (e.g. Domestos). And consider using a rim block or cistern block to prevent future re-encrustment.

I can't help with the shower though.

Harpic limescale remover for the toilet and any mould remover spray. Be sure to follow the instructions and keep your shower room as ventilated as possible

Beware cistern blocks. They can 'gum up' things.

Black mould in the shower- first you need to attack the moisture problem, which enables the mould to thrive. Dry the tiles and sealant and shower tray and window condensation after every shower (maybe a karcher window vac followed by a cloth); ventilate the room.
When it starts to reappear, you can use a paste of baking soda and a drop of vinegar, applied generously with an old toothbrush and left to do its work.
If the mould appears on the walls and ceiling, there's definitely a ventilation problem. You can get anti-mould paint and that will help.
