Cleaning build up of limescale on shower tray

[RavenVonChaos]

Help! Please. Has metal rim so can't use anything that will affect the metal.
Thanks

Viacal is pretty much the best for pure dissolvability, but I quite like the cilit bang in the orange bottle too - works a treat if you leave it on for a while. Then use to keep it clean and it won't build up again. I use it on my sink and it doesn't affect the metal around the plug.

Magic erasers are quite good too if it's making it a bit stained.

Don't use harsh cleaners try the rubber first. Only put limescale removers on it for a small amount of time maybe 2 minutes and then repeat, you want it to attack the limescale not your shower tray.

Limelight (sp?) is very good

Another vote for limelight!

Thanks have just spent an hour cleaning my disgusting bathroom

Will try your suggestions x

this is not the sort of answer you expected, but if you can afford a water softener you will be amazed at what a difference it makes (the big ones with a salt reservoir that work by ionic exchange, not the little magnetic things that work by magic and faith)

Ecover Toilet Cleaner painted on works amazingly fast.
