Hi
I don't want to throw a curved ball in here, but has anyone tried Harpic Power Plus toilet cleaner to remove limescale.
I put some around the basin taps the other day where there is always a buildup of limescale, left it for a few minutes and wiped it off. I've always scrapped it off before.
Is see it contains Hydrochloric acid and needs to be treated with caution and handled correctly.
The Americans recommend Muriatic acid for cleaning windows which is the same stuff but warn against uncontrolled use as it will kill plants nearby or animals if they ingest it. So I won't consider using it if there was a fish pond in the vicinity.
I have just tested some on the corner of our kitchen window. Put it on with a paper towel on the glass, rubber and upvc, left it for a few minutes and hosed it off whilst in my bare feet. No effect yet recorded and window components seem fine.
As take no responsibility for the recomendation or use of this product at all. Used entirely at your own risk.
