Oust All Purpose Descaler
Disadvantages: Doesn't work
Alright, I admit it. My kettle's a state. It's about a year (!) since I last descaled it and both exterior and interior are crusted with nasty, chalky limescale. The time has come to test some descaling products!
Oust Descaler consists of a small box containing three 25ml plastic sachets of liquid, costing around £1.50 for the lot. The packet boasts that the formula is new and improved, to remove 20% more limescale.
To descale a kettle, you simply half fill it with water, add a sachet, and leave it to work for ten minutes. If not all of the limescale is removed, you can then just heat the water gently until the remainder starts to fizz, removing any residue.
Does it work?
Well, if this is the formula designed to remove 20% more scale, I dread to think what this product was like before! Two sachets of it barely tickled the crust in the kettle.
The first sachet I used, I followed the instructions to the letter. It removed a couple of large pieces of limescale, but the crust of it on the base of my kettle was left largely untouched. I reheated the solution, and removed a little bit more, but I doubt that anyone seeing 'before' and 'after' pics would have seen much difference. Refilling the kettle and boiling it again with fresh water didn't produce any further results.
So I tried a second sachet. As my kettle is quite large in its capacity, I decided to put in a lot less water, so the solution would be more concentrated. Ten minutes later, a couple more pieces had flaked off, but there was still no great improvement.
Annoyed, I rinsed out the kettle, boiled a load of clean water, threw it away, and turned to using Ecover's limescale removing spray. This did a terrific job, and you can get a whole bottle of it (enough to descale your kettle many times over) for £3.
Oust might work to maintain your kettle if you use it regularly, but if you really need to remove limescale quickly and easily, there are much better and greener products on the market that do a superior job.
Summary: Not recommended.
