Oust Powerful All Purpose Liquid Descaler, Limescale Remover – Ideal for Kettles, Coffee Machines, Irons and Shower Heads (500 ml x8), multicoloured

Love the fact it’s citric and not chemical.Nice safety cap to deter any unwanted visitor.No nasty steam inhalation.Does the Job perfectly.

This is the best coffee machine descaler on the market, and at just over £21.00 for 8 bottles it's also tremendous value for money.

Works really well removing hard limescale, does take a few goes if limescale builds up. But persistence works. Well worth the cost

Oust has been a leading descaler for many years. Brings kettles up like new. removes limescales from all surfaces with no bother at all. Highly recommended.

Ideal for coffee machines & kettles

1. Thumbs up to Amazon for quick delivery!2. It does the job well, although 100-150ml of the descaler is required and less concentrated than those 3x 25ml sachets. No fizz during 1hr descaling process though.3. Would be great if Oust released more concentrated descaler in bottles.

Removes lime scale

Have bought Oust products from the supermarket for years and they have always worked well. The product from this seller did not match expectations and appears very dilute, to the point that it failed to remove scale from the inside of the kettle and the shower head. I even tried using a more concentrated mixture, leaving it for far longer than instructed but still to no effect. A waste of money.
