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)

An excellent APC (All Purpose Cleaner) that’s very safe and effective. You can clean an engine bay and scrub the biracial plastic trim. It’s also highly dilutable. Turns out that’s it very cost effective as well. Always test on a small area first.

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!

Great dilutability, versatility, and price point.

The ish. Works on everything.

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.

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.

Good product, needs dilute

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.
