w4 Citrus Foam

First time using this but have to say it’s really good stuff. Seen a few comments about beading and water not running off on other Gtechniq products, seriously, do people think the rain will dodge their cars after applying? It’s good but not that good!!

One of the best snow foams I’ve used. Combined with next day delivery and the same price as direct purchase. This was a win win purchase.

I've used a lot of different snow foams over the years, and this is one of the fairly good ones. I only say "fairly good", because to be honest, I've never found one which particularly astounding. Most don't produce a really thick, clinging foam without using a fair bit more than the advised amount. This Gtechniq W4 is a bit thicker, so likely a bit more concentrated than others, so you do need to use less than other brands, but it does cost a bit more (1l of this might be 2.5l of another brand, but you'll use 2.5+ times as much with some other brands). Gtechniq W4 does a good job of softening baked on insects, mud, grime and bird muck - which is basically what it is for. It isn't a contactless wash, meaning you will still need to do a regular contact wash afterwards (e.g. buckets and a wash mitt), but it does make it that much easier and quicker. The other plus is that it smells pretty nice too!

This snow foam does not produce the most luxurious foam, but it does possess a very powerful degreasing agent which most snowfoams don’t. It does produce a deep clean on the car without stripping any coatings, so I'm not intending to use it for every wash but instead will use it 2 or maybe 3 times during the year, such as after the winter months, to get rid of any collected grime, salt etc . Nothing to say you couldn’t use it for every wash but for most maintenance washes I’ll stick to my Bilt Hamber Autofoam. It does provide something “ extra” and it’s very good at what it does.

Great product never had a bad purchase from Gtechnig

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

I really like this car shampoo. A little goes a long way and I love the fact that it doesn’t leave any streakiness on the car. It rinses off really well. Cleaning power is great and it doesn’t appear to strip any of the existing protection already on the paintwork. It’s now my go-to shampoo.

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'idropulitrice Non funziona con un erogatore spray manuale o/e pressione. Ottimo prodotto se si hanno gli strumenti corretti.

Produit qui s'applique bien avec mon nettoyeur haute pression. Je suis content du résultat. Le flacon était très bien emballé.

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!!

All gtechniq products work amazing! Just tried this and I love how it breaks down dirt and grime 👌 and the foaming was great!

I had my SUV professionally ceramic coated with Gtechniq products and I can't say enough great things about it! All their products are amazing. It's all I use now and couldn't be happier. Love Gtechniq!
