Strength.
Problem solved.
Full-Bore Solvent Strength. Tar · Sap · Rubber · Grease · Adhesive. When you need it off in one shot — this is what you reach for.
Eulex is Koch Chemie's full-strength tar and adhesive remover — the product you reach for when the job calls for a single, decisive pass and you need the contamination gone. Tar spots, tree sap, rubber transfer, oil, grease, badge adhesive, dealer stickers: Eulex removes them from any surface capable of resisting a solvent-based cleaner.
The application is straightforward. Apply to a clean towel and hold against the affected surface for a moment, then wipe away. Stubborn contamination gets a soaked swatch left to dwell — the solvent does the work. What you don't get here is a product you're nursing along for results. Eulex is decisive by design.
Know your surfaces before you use it. Eulex is not for powder-coated finishes. Shake before use, and use a towel you're prepared to retire from paint duty — solvent-contaminated microfiber is floor cloth from that point forward.

"When you need it off in one pass — not two, not with a follow-up product, not while wondering if it worked — Eulex is the answer."
— Detail Division · on Koch Chemie EulexWhat Eulex removes
Tar & Road Contamination The core use case — road tar adhered to paint and lower body panels. Full solvent strength means a single dwell-and-wipe removes what accumulated over hundreds of miles, without requiring repeated passes or a second product to finish the job.
Tree Sap Hardened sap bonds to clear coat and is effectively immune to wash chemistry. Eulex dissolves it. Apply to a towel, press and hold, then wipe — the dwell time does the work. Do not drag dry across the surface.
Rubber Transfer Contact marks from rubber against painted surfaces — curb strikes, tight garage clearances — respond to Eulex where detailing clay and paint-safe dressings don't cut it. The solvent lifts transfer without mechanical abrasion.
Oil & Grease Petroleum-based contamination on exterior surfaces — whether it's road film buildup on lower panels or grease from a service point — lifts cleanly without the surface work that a decontamination wash alone requires.
Badge & Sticker Adhesive Dealer badges, manufacturer stickers, aftermarket additions — the adhesive left behind after removal is where detailers spend time. Eulex dissolves residue cleanly, including the ghosting that panel wipes and IPA don't fully resolve.
Eulex vs. TEA — Choosing the Right Solvent
Koch Chemie makes two solvent-based removers for a reason. Eulex is the stronger product — it's the one-pass solution for serious contamination on surfaces you know can handle it. TEA (Teerwäsche A) is the controlled option — dialed back for situations where full solvent aggression is the wrong call, particularly around plastic trim or when access is tight and surface risk is higher.
If you're uncertain which to reach for: start with TEA. If TEA isn't moving the contamination with appropriate dwell time, Eulex is the next step.
Eulex — Use When
Contamination is heavy or set in
Single-pass result is the goal
Surface is confirmed solvent-safe
Not powder-coated
TEA — Use When
Working near or on plastic trim
Surface risk is a concern
Contamination is lighter
Control matters more than speed
Application Reference
Tar & Sap
Apply to towel · press and hold against contamination · wipe away · repeat if needed
Stubborn Areas
Soak a swatch · allow extended dwell · the solvent does the work · do not scrub dry
Badge Adhesive
Apply to cloth · work edges inward · lift residue cleanly · follow with panel wipe
Towel Protocol
Use a towel you're prepared to retire from paint work — solvent-contaminated cloth is floor duty only
There are products that remove contamination eventually, and products that remove it now. Eulex is the latter. Know your surfaces, shake the bottle, and let the solvent do what it's built to do.
Directions & Key Notes
Shake before use — every time
Apply to towel · press · dwell · wipe
Stubborn spots: soak swatch and dwell longer
Confirm surface is solvent-compatible first
Not for powder-coated surfaces
Retire solvent towels from paint work
Not compatible with powder-coated surfaces. Always read labels and confirm surface compatibility before application. When in doubt about a surface, reach for TEA first — it offers the same contamination-removal capability at reduced solvent aggression, with more margin on unfamiliar or sensitive finishes.
Use a suitable towel — and demote it immediately. A cloth used with Eulex picks up dissolved tar, adhesive, and solvent. It is no longer appropriate for paint surfaces after this use. Keep a dedicated stack for solvent work, or use disposable shop towels. Contaminating your panel microfiber is an easy mistake to make once.
