Inspect the Appliance First

• Examine the stained area carefully to understand the extent of discoloration. Look for signs of wear that might affect cleaning method options.
• Test a small area discreetly to ensure the cleaning method won’t affect the plastic’s finish before fully committing.

Mix a Gentle Cleaning Solution

• Create a low-impact cleaner by combining warm water with a few drops of a mild dish detergent. The warmth helps lift ingrained particles while the detergent breaks down oily residues.
• Consider a baking soda paste for stubborn yellowing. Mix baking soda with just enough water to form a thick, spreadable paste. Baking soda is mildly abrasive without being harsh, which can help lift the discoloration without scratching the plastic.

Apply, Agitate, and Let Sit

• Using a soft, non-abrasive cloth or sponge, apply your chosen solution over the stained area.
• Gently scrub in circular motions. Circular movements help work the solution into the plastic’s surface evenly; be careful not to apply excessive pressure that might create scratches.
• For the baking soda paste, it can be beneficial to let it sit on the stain for several minutes to loosen the discoloration before scrubbing.

Rinse and Dry Thoroughly

• Rinse off the cleaning solution completely using a clean, damp cloth to ensure no residue is left behind that could cause further spotting or streaks.
• Dry the area with a soft towel immediately. This step helps prevent water marks and allows you to see if additional treatment is required.

Review and Repeat if Needed

• Inspect the results after drying. If the yellowing hasn’t diminished to your satisfaction, repeat the process. Persistence often pays off with deeper, older stains.
• Regular upkeep can help prevent reoccurrence. A light wipe-down routinely may reduce the build-up of substances that cause yellowing over time.
