No, not me but for my niece who says the limescale is bad in her bathroom. I searched Limescale here on AB and a few products came up. But that was in 2018 - has anybody bought anything really good recently as I could buy it for her.
I use white vinegar in a spray bottle, multiples of 100ml vinegar to 50ml water with a drop of oil essence to mask the smell. Spray on and leave for about 15 mins, wash of with some cilit bang soap suds remover, then rinsed. It has got rid of all the build up in my shower and now keeps it at bay.
her mother has tried the white vinegar and baking soda but it sorta remains there, do think niece should be treating it every day but isn't so I believe it builds up quite quickly.
I had been thinking perhaps of tablets you could put into the cistern every night (if there's such a thing)
There is a make called Astonish which only costs around a £1 and they do a limescale remover. I have tried a number of their products and they seem to work quite well.
JJ, once she has cleaned it off make sure she doesn't let it build up again. Wipe everything immediately after use with a dry microfibre cloth. Takes seconds and saves much aggro.
