Koche Chemie (GS) Green Star 1L

Koch Chemie (GS) Green Star is a highly concentrated, phosphate and solvent free, alkaline universal cleaner that removes tough dirt, oils and more. Safe for exteriors, interiors, engine bays and more.

This all purpose cleaner doesn’t play around when it comes to shifting stubborn grime. Whether you’re degreasing engine bays, stripping down exterior trims, or deep cleaning interiors, Green Star can be tailored to suit nearly any task. Its pH of 12.5 gives it enough punch to cut through heavy oil, grease, and embedded dirt, yet it's balanced out with corrosion inhibitors to make it safe on sensitive surfaces like anodised aluminium.

Being phosphate and solvent-free, it's also more environmentally conscious than traditional degreasers. But this isn’t just a cleaner for wheels and engine bays. It's equally at home on plastics, trims, vinyl, and rubber when diluted correctly, which makes it a staple in both workshop bays and mobile setups. From daily maintenance to heavy detailing jobs, Green Star is a product you keep in bulk because it never stops being useful.

One of the most popular uses for Green Star is to supercharge your pre-wash routine. When combined with Koch Chemie GSF Gentle Snow Foam, Green Star gives your foam cannon mix the degreasing power it needs to break down traffic film, grime, and residue before you even lay a mitt on the paint. Just a small amount of Green Star added to your foam solution helps strip down waxes and surface oils, making it perfect for maintenance washes or prepping a surface for ceramic coatings. It creates a more effective cling and clean without affecting sensitive finishes, and it’s especially handy on ceramic coated vehicles where you want the foam to actually do something useful.

Note: The 1L variant does not come with a spray trigger
