Following up on my post yesterday when I tried WD40 on my headlight glass, it sort of worked. This morning I rubbed them with baking soda. What a difference, perfectly clear.
Last night I saw an ad on Ch4 for Oral B Whitening Toothpaste available for 50% off, at only £9 a tube as opposed to £18........yes, for a tube of toothpaste. I had also known that baking soda was mildly abrasive, hence the clean headlights, so I dipped my Oral B toothbrush into some soda, cleaned my teeth, and what a difference, I open my gob and my teeth shine like my headlights. Bht 40 from Lotus's.
