Crumbs, your eye sight's good, I couldn't even make out the price on the label in real life!! In fairness, it has been kicking around for a while - used to clean the hard water streaks off the kettle with it, but then discovered WD40 did it better. I may have to dust it off and give the windows a clean...…….... sometime
Phosphoric acid will get limescale off when all else fails. Great stuff. H G limescale remover's about 15%, but for the heavy artillery a lab bottle (~80%) of it from fleaBay will shift anything
80%?? Flippin’ heck, I only clean the kettle scum if there’s visitors coming, I don’t want to actually dissolve the whole blinkin’ kettle!!
