Hi, I'm Rachel Yatuzis and I'm going to show you how to clean plastic knobs. Plastic knobs are usually found in the kitchen and the most common place would be on your stove. When you're cooking and your hands get greasy or get dirty or grease or something could splatter up onto the plastic knobs, one thing you could do is just spray an all purpose cleaner onto a rag and spot clean the knobs. If you're looking for a more deep clean, and you want to clean the back of the knobs also, you want to just pull them off and pop them in the dishwasher into where you would put your silverware, into the silverware tray that's in the dishwasher. Also, if you're washing dishes and you want to let them soak in the soapy water, if their really dirty you can do that also. Then just replace your plastic knobs and they will be all clean and ready for the grease to splatter back up on them again. I'm Rachel Yatuzis and that's how you clean plastic knobs.
