Expert Notes

YumCars Undress is designed to solve one of the biggest reasons tyre dressings fail early, poor surface preparation. Tyre rubber is porous and quickly holds onto old dressings, road grime, oils, traffic film and greasy residue, so applying a fresh dressing over the top often leads to patchy finish, sling and reduced durability. Undress uses a ready-to-use gel formula that clings to the sidewall, giving the cleaning agents more time to penetrate and lift contamination from the rubber. It is especially useful before applying YumCars Dress because it creates a clean, uniform surface that allows the dressing to bond more evenly. It can also be used on exterior plastics, rubber trims, wheel arch liners and engine bay plastics where old dressing, grime and greasy residue need controlled agitation and thorough rinsing.

Perfect For / Suitable Surfaces

  • Tyre sidewalls
  • Exterior rubber trims
  • Rubber mouldings
  • Engine bay plastics
  • Exterior textured plastics
  • Plastic engine covers
  • Scuttle panels
  • Plastic grilles
  • Tyre lettering

Caution: Avoid delicate interior materials, leather, suede, Alcantara, screens, polished metals, bare aluminium and hot engine components. Rinse thoroughly after cleaning and allow tyres to dry before applying dressing.

How To Use

Tyre sidewall cleaning

  1. Make sure the tyre is cool before application.
  2. Rinse the tyre to remove loose dirt and grit.
  3. Spray Undress generously onto the tyre sidewall.
  4. Allow a short dwell time for the gel to penetrate contamination.
  5. Agitate thoroughly using a dedicated tyre brush.
  6. Work around the full tyre sidewall.
  7. Rinse thoroughly with clean water or a pressure washer.
  8. Repeat the process if brown residue or dirty foam remains.
  9. Allow the tyre to dry fully before applying dressing.

Exterior plastic and rubber trim cleaning

  1. Make sure the trim is cool and suitable for cleaning.
  2. Spray Undress directly onto the plastic or rubber surface.
  3. Allow a short dwell time without letting the product dry.
  4. Agitate using a suitable detailing brush.
  5. Work carefully around textured areas and edges.
  6. Rinse thoroughly with clean water.
  7. Dry the surface before applying a trim dressing or protectant.

Top Tip: Repeat the cleaning process until the foam stays much cleaner, as this shows old dressing and ingrained contamination have been properly removed from the tyre rubber.

Why should I clean tyres before dressing them?

How do I know when my tyres are clean?

Repeat cleaning until the foam or rinse water remains much cleaner and the sidewall no longer releases brown residue.

Can Undress be used in engine bays?

Yes, it can be used on suitable cool engine bay plastics, but avoid sensitive electrical components and rinse or wipe carefully.

Do I need a tyre brush with Undress?

Yes, agitation with a dedicated tyre brush helps lift contamination from the pores of the rubber for the best result.

Once the tyre or trim is clean and dry, apply YumCars Dress or a suitable tyre and trim dressing.
