How To Clean and Maintain Your Number Plates
We've seen all sorts come into the workshop. Plates full of grime, faded lettering, or cracking from years of sun and road dirt. Truth is, most of that can be avoided with a bit of care. Here's a proper guide on how to clean and look after your number plates, whether they're standard, 3D gel, or 4D.
Why cleaning matters
A dirty plate can actually get you pulled over. If a police officer can't read it clearly, you could get fined. MOT testers also check for legibility. So even if you don't care about looks, clean plates keep you legal.
What you need
- Soft sponge or microfibre cloth
- Mild car shampoo or soapy water
- Clean water to rinse
- Optional: plastic polish for acrylic
Avoid anything rough or gritty. No scouring pads or strong chemicals. These can scratch or damage the raised letters.
Step-by-step cleaning
- Rinse the plate first to remove loose dirt.
- Use a soft sponge and mild soap to gently wipe down the plate. Get in the corners too.
- Rinse again with clean water.
- Pat dry with a soft towel or cloth.
- For 3D gel or 4D plates, you can use a tiny bit of plastic polish to bring the shine back—but only if it's meant for acrylic.
What to avoid
Don't use pressure washers too close to the plate. They can loosen the letters or even rip them off over time.
Also, avoid automatic car washes with heavy brushes. We've seen loads of plates get scratched, cracked, or ripped off completely.
How often should you clean them?
If you drive a lot, once every couple of weeks is a good rule. During winter or bad weather, even more often. Salt and grit from the road will eat into materials if left too long.
Long-term care
If your plate starts peeling, bubbling, or fading, that's not normal. Good plates should last years. We only use high-grade materials that stand up to rain, sun, and road dirt.
But if something does go wrong, we'll help sort it.
