Kilrock Big K Multi-Purpose Limescale Remover 400 ml, Yellow, Pack of 2

Very effective at descaling my kettle even using half the quantity suggested on the measure so goes a long way and economical.

I am so sad that I look forward to defuzzing my kettle as watching Big K work its magic is honestly one of the most satisfying things ever! I live in a super hard water area, so limescale is a nightmare in all my sinks, toilets, shower and kettle, but this sorts it out with zero effort in a matter of seconds! My advice is to use the instructions - it works much better when mixed with hot water (especially in the toilet bowl). I used a plant spray bottle to make my own mix up, so that I could do the walls and silver wall attachments in my shower, and that made it last far longer. Also things like around the base of taps where water leaks - give it a go!

Good descaler

I've bought these before. In my opinion the best descalier on the market.

The product is fine however, I ordered 2 and when they arrived, one container was almost empty as the lid was loose and it had leaked out. NOT a good seller.

Quick delivery and another great product by Kilrock

Easy and quick to use. Bottle packaging was slightly suspect and one of the bottle tops leaked.

Honestly I've tried so many descaling solutions so this was a last ditch attempt. It's quite frankly magic. Oust descaler took most of a day and still didn't descale my kettle properly. This took less than 30 seconds and it looks brand new! Poured it on my taps, used it in the coffee machine, cleaned the shower and more. Even bought the gel version for things where it can't stay immersed. Genuinely shocked how good it is.
