Koch Chemie Eulex is a professional-grade adhesive remover and solvent cleaner trusted in detailing shops and automotive workshops worldwide. It rapidly dissolves sticker residue, tar, tree sap, rubber marks, grease, oil, ink, and other stubborn bonded contamination from paint, glass, ceramic, chrome, and metal surfaces. Fast-acting and thorough, it handles removal jobs that standard cleaners and degreasers cannot touch.

Evaporates quickly without leaving behind any oily film or residue, so surfaces are ready for the next step immediately after use. Contains no halogenated hydrocarbons, making it a safer formulation compared to many heavy-duty solvents. Daimler approved for professional automotive use, which speaks to its quality and safety on vehicle paintwork and surfaces.

If you are looking for the best automotive adhesive remover for professional detailing, a tar and tree sap remover safe on car paint, or a Koch Chemie solvent cleaner for workshop and reconditioning use, Eulex is the benchmark product from one of the most respected names in professional detailing chemistry. Available in 1L and 5L.

Koch Chemie Eulex Usage

Eulex is Koch Chemie's adhesive, tar, tree sap, and bug splatter remover — powerful solvent-based decontaminant for stubborn surface contamination that survives a normal wash.

• Application: Spray directly onto contamination. Allow 30-60 seconds dwell. Wipe with a clean microfiber.
• Heavy tar or adhesive: Repeat application and dwell. For adhesive residue (stickers, emblems), saturate, dwell 2-3 min, wipe.
• Follow-up: Wash area with shampoo (CES/GSF) to neutralize. Eulex can strip wax/sealant in the treated spot.

Frequently Asked Questions

Is Koch Chemie Eulex safe on paint?

Yes, at normal dwell times (30-60 sec). It's solvent-based so it can strip wax/sealant from the treated spot — reapply protection after decon. Don't let Eulex dwell more than 2-3 minutes on paint.

Koch Chemie Eulex vs Goo Gone — which is stronger?

Eulex is professional-grade and purpose-built for automotive surfaces. Goo Gone works on adhesive but is slower and not automotive-tested for paint safety. For detail shop use, Eulex. For home use on non-auto surfaces, either.

Will Koch Chemie Eulex remove tree sap?

Yes — tree sap is one of its primary use cases. Spray, dwell 1-2 min, wipe with a clean microfiber. Repeat if sap has hardened. Always follow with a wash to remove solvent residue and restore protection.
