How to Whiten Yellowed Plastic

Yellowness on plastic is quite common. And this doesn’t mean that the window sill or refrigerator is not cleaned often enough.

Like many people nowadays, I love to explore new places. My favorite type is slow travelling, when you can really blend in with locals and learn about new cultures and languages. But I think there are also perfect times for enjoying freshly baked pastry, a cup of fragrant coffee, and a good movie in the comfort of your own home. I guess I'm kind of a cultural omnivore, and I watch different types of movies, but the ones about art and food inspire me the most!
