Step 1: Wash your headlights first. Wash using dishsoap and water, pat it dry. You might want to use a soft microfiber cloth and make sure there is no lint or debris left on the headlight. Once it is dry, you need to concoct a cleaning solution.
Step 2: Create a really thick paste with baking soda and water. Three times the powder for water ratio. It needs to be thick, but not dry. Start with three heaping tablespoons of baking soda. Add water a tablespoon at a time. Stir it into the baking soda until it's a thick paste. The consitency of toothpaste is what you are looking for. Once you have the right thickness, add a tablespoon of kosher salt and stir again.
Step 3: Apply the baking soda mixture to a clean, damp microfiber cloth. Rub it into the headlight in a circular motion, covering the entire headlight. If the headlight is very cloudy and hasn't been cleaned in a while, a little elbow grease will be necessary. As you rub, you will see the headlight start to turn clear again. Apply more if needed.
Step 4: Use a wet microfiber cloth to lift and remove the baking soda that remains on the headlight. It may have caked up, so be sure to remove it completely. Take care not to scratch the lights in the process. If you are not able to remove all of the baking powder from the crevices around the headlight, spray it down with water until it is gone.
Clean headlights can make a world of difference to the way a vehicle looks. It is relatively easy to clean and polish your vehicle's metal parts, but the plastic bits are often overlooked. Over time, it is going to get cloudy and make the whole vehicle look old and worn out. That is not something you want to sit through. Apart from looking bad, your car's lights will not be able to put through a strong beam in front of you, causing a lot of distortion to the light, and it will simply not be in focus. Cleaning your headlights with baking soda is an easy fix. I'll tell you exactly how to do it below.
There are a number of specific products that claim to work really well on headlights. I've tried a few of them, each costing between $10 and $15. While some of them work to a certain extent, this fix is near perfect and costs next to nothing. Like the other green cleaning tips on our website, it can be done at home with stuff that is already in your kitchen.
If you do not have any baking soda around, this exact thing can be done with toothpaste, just remember to always use the generic, white creamy paste with no gel or anything else. Dental cream-like paste only. Gels and other complicated pastes will not work. Just apply a nice layer of paste exactly as mentioned with the baking soda, and wipe it off.
