My shower cubical was installed about 18 years ago, and is looking a bit grubby.
It's got a decent sized rectangular tray made of something fairly solid with a glazed surface. It's in a corner of the en-suite, with two walls tiled and glass of some sort in (powder coated?) metal frames on the other two sides, with a door in the long side.
The grout between the tiles is a bit discoloured. It can be improved by scrubbing it with an old toothbrush with some Jif on - but this is a bit tedious. Likewise the tray. Likewise the metal frames. The glass sides are suffering from limescale from hard water, and previous attempts to clean them with Jif, Cillit Bang, etc. haven't been very successful.
Any bright ideas as to how to liven it up without too much effort? I have in mind something like a pressure washer (or steam cleaner?) but a full-size pressure washer as used outside would be a bit unwieldy and may cause some damage. Anyone ever seen a smaller, less powerful, one for indoor use?
Any other ideas - spray-on chemicals, etc.?
TIA.
