Scrub the plastic items with a damp rag until they become clear. Rinse the no longer foggy plastic in the sink under warm water. Dry with a soft cloth.
As the paste removes the cloudiness from the inside of the blender or cup you’re cleaning, you will see the paper towel darken with grime.
There is no need to carefully measure the volume of baking soda and vinegar you mix. Just add both in approximately equal amounts.
Don’t worry about hurting yourself when dipping your hand in the fizzy mixture. The combination of baking soda and vinegar won’t hurt you. When you’ve finished cleaning the headlight with the vinegar mix, wipe the headlights dry with a damp cloth or sponge.
If the headlight’s surface is not uniform in appearance, wipe the headlight down again with 2000 or 3000 grit sandpaper while spraying it with soapy water.
Use only a slight pressure when applying the polisher pad to the headlight. This step will remove any haziness that remains from the sanding process.
When you’re done, wipe the headlight off with a dry hand towel. Remove the tape surrounding the edges of the headlight. At this point, no fogginess should remain and the plastic headlight should be clear. If some fogginess remains, apply another coat of finishing polish, then wipe it away with a clean hand towel.
