## Questions & Answers

**Q: Is it safe to use on bicycle? A specially on disc brakes?**
A: It's a pH neutral cleaning product. It's safe use on anything. Not sure why you'd wanna use it on a bicycle though.

**Q: Can this be used on metallic matte paint?**
A: yes it's purely biological, no chemicals so lifts dirt, leave 5 mins and towel dry. suggest you do it in stages. It dries in 5 minutes so unless your Usain Bolt you will have trouble getting round the whole car before it dries and could leave smears. Worth getting the hand glove to make sure the foam spreads across all surfaces and you will need either a snow lance for a high pressure washer or at least a pressure washer bottle if you are to get foam rather than washing up bubbles. Used on two cars both metallic with success my son say's the trick is to use it regularly and you will spend 15 minutes washing a car rather than an hour and the hard work is done for you.

**Q: Can this be used in a similar way to citrus pre wash but in a snow foam lance instead?**
A: Yes it can I use it as a pre wash through a foam lance

**Q: Hi what’s the dwelling period for this product?**
A: 3 to 5 mins, don't let it dry.  By 5 mins the foam has generally slid off the car, it's not like snow foams that hang on the bodywork for a long time.

### ⭐⭐⭐⭐⭐ Great stuff!

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!!

### ⭐⭐⭐⭐⭐ Good performance and value
*by J***S on 7 August 2025*

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.

### ⭐⭐⭐⭐ Good, and smells nice, but need to use more than instructed for a proper thick foam
*by A***R on 23 July 2024*

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!
