Shower cleaning advice please

[Sonnet]

I am after some advice on a method of cleaning my shower. It is a double shower with a fixed head and 3 tiled walls and a double glass door. It is really difficult to clean as you have to be in it and rinsing is really hard using a cloth.
Am I missing a trick?

I am planning on giving it a deep clean as it is looking surface clean but grubby if you look closely.

Has anyone any tips please?

Bump .. I am going to have to start in a minute :) I keep putting it off

We use the Method shower and bathroom cleaner. Just spray, leave for a few minutes and wipe wipe with a damp cloth.

You could use a washing up bowl/bucket of water to have fresh water to clean.

I clean the shower while showering - makes it much easier! After cleaning I spray grout, etc with dettol mould and mildew remover, leave it for a while and then rinse - makes everything white again

I have a RINSEROO! It's an amazing slip on handheld shower rinser that fits all shower heads, tub faucets and sinks. Slips on and off in seconds and rinses my entire shower in seconds. I use one for all the showers in my house. Best money I ever spent.
