The right method step by step
Step 1: First, clean thoroughly.
Use warm water and a mild detergent to remove dirt and grease.
Step 2: Use a gentle approach.
For mild yellowing, baking soda (mixed with water to form a paste) can gently help.
Step 3: Hydrogen peroxide (for stubborn yellowing)
A commonly used method is applying a hydrogen peroxide solution (often in gel form). This can help reduce discoloration.
Apply evenly.
Let it act (often in combination with light).
Rinse thoroughly.
Step 4: Let dry and check.
Repeat if necessary, but always carefully.
Why this method works
Hydrogen peroxide can partially reverse oxidation processes in the plastic, especially in cases of surface discoloration.
But please note: this does not always work completely and the effect can be temporary.
Important points to consider
Always test on a small, inconspicuous area first
Wear gloves when using chemical products
Avoid excessive scrubbing
Do not expect a perfect “new” result with old plastic
What cannot be repaired?
