No — you shouldn’t use dubbin on synthetic leather.
Synthetic leather isn’t real leather; it’s plastic-based and non-porous, so dubbin can’t absorb or condition it. Instead, it just sits on the surface, leaving a greasy or sticky layer.

Let’s break down why — and what you can use instead.

Why Dubbin Doesn’t Work on Synthetic Leather

  • Dubbin can clog the surface and make boots shiny or sticky.

  • It may cause peeling or dull patches over time.

  • It’s made for natural, porous leather, not coated plastics.

So if you’re using Dr. Martens Dubbin or Saphir Dubbin, save it for your real leather boots, not synthetic ones.

Can You Use Dubbin on Suede or Nubuck Leather?

No — dubbin should not be used on suede or nubuck.
Both are real leathers but have delicate textures.

  • Dubbin darkens and flattens the surface.

  • Instead, use special suede/nubuck protectors like:

    • Scotchgard Suede & Nubuck Protector

    • Nikwax Nubuck & Suede Proof

  • After cleaning, brush the nap gently to restore the soft look.

How To Care For Synthetic Boots!

If you’re wondering what can I use on synthetic leather or how to treat synthetic leather boots, here’s the right way:

1. Clean properly:

  • Wipe dirt with a damp cloth and mild soap.

  • Avoid soaking or scrubbing harshly.

2. Condition lightly:

  • Use a synthetic leather conditioner or PVC protectant to prevent cracking.

3. Waterproof safely:

  • Use silicone-based sprays for waterproofing.

  • Avoid greasy waxes or oils.

Recommended options:

  • Crep Protect Spray – for sneakers and faux leather.

  • Nikwax Fabric & Leather Proof – works on mixed materials.

  • Kiwi Protect-All – adds water and stain resistance.

What Is Synthetic Leather?

Synthetic leather (also called faux or PU leather) is:

  • Made from polyurethane (PU) or PVC plastic.

  • Designed to look like real leather, but it’s not animal hide.

  • Non-absorbent, so waxes and oils can’t penetrate it.

That’s why dubbin wax, which works by soaking into real leather fibers, doesn’t work on synthetics.

Conclusion

So, can you use dubbin on synthetic leather?
No — it’s only for natural leather. Use silicone sprays or synthetic protectors instead to keep faux, suede, and nubuck boots in good shape.
