Carplan Demon Clean

CRACKING price for a big litre pack ensures Demon Clean goes one better than last year and takes the test win. While a price advantage certainly helps in a closely matched test, this spinoff from the Demon Shine rinse aid proved very effective on our test tailgate panel. The citrus-scented formula goes on in a wide spray and made good progress on the tricky chocolate and butter. We also like the fact you can use it on the car exterior, too. A worthy champion.
