Avoid leaving the paste on for too long, as excessive exposure to moisture can potentially harm older plastics. If the phone feels warm or the paste begins to dry out, it’s a sign to proceed to the next step. This method is particularly useful for surface-level yellowing and is a safer alternative to harsher chemicals.
Once the paste has sat for the recommended time, gently scrub the treated areas with the soft-bristled toothbrush or cloth. Use circular motions to lift away the paste and the yellowed residue. For stubborn stains, reapply the paste and repeat the process. After scrubbing, rinse the phone thoroughly with lukewarm water to remove any remaining baking soda. Ensure all residue is washed away to prevent a filmy or gritty texture.
Finally, dry the phone completely with a clean, dry towel. Inspect the treated areas to assess the results. If some yellowing remains, you can repeat the baking soda paste application. This method is safe to use multiple times, making it a reliable choice for restoring the original color of your plastic rotary phone. With patience and care, the baking soda paste application can effectively reduce or eliminate yellow discoloration, bringing new life to your vintage device.
