Make-It Monday: Second attempt to defog headlights

After my failed attempt to defog the headlights on the Amazing Technicolor Dreamcar a couple of weeks ago, my mom mentioned something she’d read on one of those Facebook clickbait posts that suggested spraying the headlight covers with bug repellent and simply wiping away the fog and scratches.

I’d heard of doing this, but the people who had tried it gave very mixed reviews. Some people swore by it. Some people said it did nothing. And several people said it produced nice results, but only on a very temporary basis, as the chemical softens the surface of the plastic, essentially melting away the scratches and leaving the lenses much more vulnerable to future damage.

Based on those reviews, I was reluctant to use that approach, but after the other methods failed, I figured I might was well give it a shot. If I didn’t do anything, I would have to buy new lenses. If it didn’t work, I would have to buy new lenses. If it worked, even temporarily, I might buy myself a few more weeks — perhaps even long enough to finish paying off that dead Subaru — before I had to sink money into replacements.

I really had nothing to lose, so I grabbed the bug spray and headed out to the driveway.

Y’all. Y’ALL. I have never seen anything like this in my life. I can’t decide whether this is beautiful or terrifying.

Here is one of the headlights before I started:

Have I mentioned how much I hate the black walnut tree next door?

Here is one after I treated them with toothpaste, Scotch-Brite pads, olive oil and lemon juice, WD-40, and a sock stretched over a belt sander:

At least it’s shiny again. Sort of.

And here they are after I sprayed them with bug repellent and wiped them off:

Almost new, and this has lasted over two weeks. The previous effort fogged up after the first rain.

They’ve held up for at least two weeks, and I noticed as I was leaving work the other night that the reflection of my headlights in one of our office windows was MUCH brighter and clearer than it had been before I treated them.

There is no question the bug spray melts the plastic. You can feel it when you’re wiping it down. It’s sticky. There is absolutely no way I would recommend using this method on a car with a nice factory paint job, because if this stuff will melt plastic, there’s no telling what it will do to your clearcoat. And I’m not sure I ever wanted to know that the bug repellent I put on my arms to ward off mosquitoes is capable of dissolving hard plastic.

That said, if your headlights have gotten so foggy as to reduce your visibility at night, and you just need to keep them going long enough to save up a few bucks to replace them, this is a fast, cheap way to do it.

Protip: If I were concerned about my paint, I’d apply masking tape around the edges of the headlights, wipe the bug repellent on with a rag to eliminate the risk of overspray, and follow up with a quick trip through the car wash.

Eco-Saturday: Check your tire pressure

Have you checked the air pressure in your car’s tires lately?

According to the EPA, you can boost your fuel economy anywhere from 0.6 percent to 3 percent just by keeping your tires inflated to the level recommended by your owner’s manual.

Properly inflated tires last longer, too, which helps conserve money and resources in the long run.

There are dozens of pressure gauges on the market. Invest in one and use it regularly to keep your car running efficiently and safely.

It’s a good idea to check your tire pressure regularly all year, but this time of year is especially important, because changes in temperature affect air pressure, and I’ve seen tires that were inflated to the correct level on an 80-degree afternoon drop by 5 psi or more overnight because the temperature dropped. A couple of years ago, we went to visit Ron’s family in central Illinois, which is about two planting zones north of us. The weather was warm when we left Southeast Missouri that morning, but thanks to a cold front moving in from the north, the temperature dropped about 40 degrees in the span of 200 miles, and as we headed home that night, the low-pressure warning light came on about 15 miles from my in-laws’ farm. We pulled into a gas station and discovered all four tires were running at 30 to 35 psi — well below the recommended pressure of 40.

Half a percent might not seem like much, but it adds up quickly — especially when you consider the cumulative environmental impact of millions of cars rolling around on underinflated tires — and it’s well worth the five or 10 minutes it takes to check your pressure a couple of times a week and top it up as needed.
