Koch chemie green star review

Hi all

First things first, I bought this product with my own money and have received nothing free from any retailer or manufacturer (unfortunately!).

I've recently been trying to find a pre wash which really works and takes off the crud as I keep finding that snowfoam just doesn't take that much off. It's great to see a decent clingy foam but if you rinse and let it dry it's just as dirty.

So that's why I decided to try Koch Chemie Green Star.

First things first.. getting hold of it. OH MY DAYS. The biggest pain in my a... everywhere was out of stock. I messaged the KC Facebook page and they said there should be some coming soon. I eventually found some after seeing the KC Facebook post about it being in stock and got myself 3 bottles from a different retailer as I needed to buy some extra bits too.

So I got it through in a few days £5.15 per litre bottle. Pretty cheap really, but when adding postage it can be a bit of a pain.

Anyway! My car was sealed with fusso soft 99 about 5 months ago and hadn't been washed in over 2 months. Over 2 months of grimey crud being baked on, mud from country lanes and all the usual you find. As you can see, it was really caked on!









I diluted 250ml of green star with 2l of water and applied it with a cheap pressure sprayer. I rinsed with a nilfisk titan 120 pressure washer. And these were the results:







Those were the best pictures out of the ones I took due to reflection etc. I tried to let it dry naturally before taking these as it always looks cleaner when wet. As you can see it still has some crud on it, but it is massively reduced and better than any snowfoam I've tried (Valet pro, magifoam and avalanche)!


I was actually really surprised how well it worked and I'm glad I got the 3 bottles!

I finished by washing with megs gold class and it was still beading & sheeting so the fusso soft 99 has been unharmed at that dilution ratio.


Bit of a write up for you there but hopefully someone finds it useful and if you see it being sold next time you're restocking I seriously recommend getting some to try it.

Is it my PC or are these the biggest pics I've ever seen on DW?

I was looking forward to the review but it's spoilt by the huuuuuge pics embedded onto the thread.

Any chance you can make the pics smaller Ben?

Worth noting that the OP has used a powerful APC at a 12.5% dilution - nothing wrong with that, but it should be expected to clean very well! It won't strip LSPs off in one hit, but I'd be astonished if it didn't knock it back faster than a "normal" snowfoam. Not that this is a problem per se, LSPs can always be reapplied, but worth bearing in mind if you're thinking of doing this.

Thanks to the OP for showing us one way to deal with a properly manky vehicle

Done. Samsung s7 has no resize function which was a PITA and I couldn't be bothered to download separate tool

Ha ha, cheers pal.

Looks like you weren't disappointed with the KC then.

It's come up a whole lot cleaner for sure.

I wouldn't usually use that strong, but as it hadn't been washed in a long time I decided to give it a wack. Next time will be more like 5%.

Worth noting that neat snowfoam has never cleaned like this stuff.

I always tend to find snowfoam only takes off the loose stuff which the pressure washer would take off anyway. I've never found one that really wowed me.. but this stuff has.

Definitely worth it for the price. Probably my best buy in a while. Other than my DA haha

I actually bought it because I saw your review as I'm a bit fed up of using a load of foam and getting nowhere.

Then when I tried it I thought it was good enough to make me want to write something up to support your review.
