Kilrock Mega-K Multi-Purpose Descaler Multipack 6x1 Litre (72 Doses) - Limescale Descaling for Kettles, Toilets, Shower Heads & Coffee Machines - Biodegradable and Phosphate Free

Definitely buy this product to get rid of ugly limescale in your loo. Purchased it years ago in Aldi or Lidl in the central specials aisles, but never saw it again. Was looking for a descaler for my loos which are really quite bad and cleaning and soda crystals and vinegar wasn't working. BUT THIS STUFF DOES. Buy it, you won't regret it. Don't need to use lots of it either. 100ml for your first OVERNIGHT soak and break up the hardened soda crystals sitting on the bottom of the bowl! Then a bit more for a 2nd soak to get the final bits off (that were under the soda crystals) and ta dah! a white bowl

Not super-strength, but adaquate.

I've always used smaller bottles before which usefully had marking on the outside of the bottle so you could use a known volume. The large bottles don't have this :-(

I’ve tried vinegar and baking soda etc but this cleans my glass kettle best. But just too expensive. So hopefully will find something else. So one star off.

Followed instructions and result was sparkling. kettle needed double go but result excellent
