Arrived as scheduled & good product.
It got a great foam that settled quickly on the paintwork. It didn't remove any dirt that I could see after rinsing but when I moved on to the wash stage with shampoo and mit the dirty removed very easily and quickly. My first time using snow foam so I may have a.few.lessons to learn yet to get the best out of it but I am.happy that the dirt that had been stood on the car several months came off so easily. The car has the Gtechniq sealant applied from new at the dealership so felt this product was a good way to enhance that treatment and protect it. There was a light citrus scent, it was easy to pour into the sprayer, car is shining well after the full wash.

Good
When I get to use with a pressure washer it will be great. From a pump bottle it was ok.

Not cheap but does a great job
Not cheap but does a great job.Had to wait an age for a dull, cool day.

Not Good Enough
Decent enough foam but just doest really shift light grime after not doing many miles and fairly dry summer conditions and a bit of rain.I wouldn't buy again as it's not worth the high price tag

Ottimo se usato con una foam gun
Ho preso questo prodotto per la mia auto...L'ho utilizzato con una Foam Hose (pistola schiuma classica no idropulitrice)Il prodotto è ottimo ma credo che dia il massimo con l'idropulitriceNon funziona con un erogatore spray manuale o/e pressione.Ottimo prodotto se si hanno gli strumenti corretti.

Thick and slick
I used this with a foam cannon on the end of a gas powered pressure washer. The foam was thick and did a great job of cutting through road spray. It is nice and slick so you are less likley to scratch your clear coat

Gute Reinigungsleistung
Die Reinigungsleistung ist wirklich bestens. Das Mischungsverhältnis ist zumindest für die Kränzle Schaumpulle etwas mager. (Das kann aber auch an der Schaumlanze liegen, Vergleiche habe ich nicht).Der Schaum tropft da etwas zu schnell ab. 50% mehr Reiniger und es wird erheblich besser. Selbst mein sehr selten ( halbjährlich) gewaschener, 20 Jahre alter Kangoo glänzte nach einer Wäsche besser als aus der Waschanlage mit Premium-Programm. Grobes mit HD vorwaschen, etwas abtropfen lassen, einschäumen, 3 Minuten wirken lassen, ein Umlauf mit der Waschbürste und Abfahrt. Den Rest macht bei mir der Wind. Gutes Produkt!!
