KOCHCHEMIE Green Star - Highly Concentrated Universal Cleaner; NTA, Phosphate, and Solvent Free, Clean Auto Interiors and Exteriors, Engines, Commercial, Home, and Industrial Use (1 Liter)

Great dilutability, versatility, and price point.

Great all purpose cleaner. I have used this in so many ways. Have added GS to GSF to increase the cleaning strength in my contact wash. Have also used this on wheels/tires at 1:10. Being able to dilute this product is fantastic.

this is a great apc. i used green star on my mats. the first set of mats are black, 7 years old out of a work truck. the second set of mats are brown from a one year old personal truck. after using gs, i didn’t need to wash mats again. how i cleaned these mats: 1. sprayed with Gs and agitated with a drill brush (i purchased a drill brush set from harbor freight). had the brush rotating clockwise and then switched to counter clockwise with the last pass. to dilute: i used the two finger rule on my spray bottle. 2. i set the mat outside, upside down in the sun for it to dry while i worked on the next mat. 3. after the mat was fully dry, i sprayed Guf (Gummifix) with a Continuous Mister Spray bottle on entire front surface of the mat and periodically sprayed my detail brush as well and worked guf fully into the mat. let it sit for a few minutes and wiped it off with a microfiber cloth. these mats looked amazing! they weren’t slippery nor glossy! my husband didn’t think i could get the work truck mats to look clean. they look better than clean, they look brand new!

It can be diluted for engine bay, wheel wells, or as a pre wash, great product.

Excellent all purpose cleaner that can do almost anything - you can use it as an additive in your foam cannon, clean engine bays, interiors, tire cleaner, even use it as a bug/tar remover. I mainly use it for heavy grime areas like door jambs and for bug removal and it works perfect. Takes bugs off better than most dedicated bug/tar removers that I've used in the past. Just make sure you dilute it properly and you're good to go.

My truck has been parked under trees for years now. I still drive it. It just gets parked at home there. With all the sap, leaf debris and whatever else drops on it, the roof was almost black. On a light grey paint. I diluted this solution 1 to 5. Made roof wet, then sprayed this mix oj & let sit for about 10 to 15 minutes. All that gunk came off with ease of a scrub brush and push broom for what I couldn't reach. Then sprayed off and amazingly it was all gone! Also used it on hood that had collected same stuff too. Amazing product. Make sure to dilute it & wash right off after scrubbing.

Does everything they said it would.

Good product, needs dilute
