How it compares on the home care & cleaning shelf

The typical home care & cleaning product on our shelf scores 4.6 out of 5, measured across 50 rated products. This one comes in at 4.6. Mid-table, in other words. The stars aren't going to pick a winner here, so it comes down to pack size, cost per unit and the details further down.

That score rests on 11,232 ratings. The median for this shelf is 6,941. That's enough for the score to mean something without being the last word on it.

On money, this sits in the middle third of a shelf running from £0.72 to £27.00, with the midpoint around £5.38. That's where most sensible buys land, neither the cheapest thing on the shelf nor the one you pay a name for.
