Headlights, Glass, and Wipers: Seeing Clearly on Dark, Rainy Eastside Nights

By Jaisen Ostrom

Hey! Once we switch off daylight saving and the rain settles in, a lot of us end up driving home in the dark on wet roads. I-405 at 5pm in November, headlights glaring off the pavement, wipers going full speed. If your glass is hazy, your wipers are streaking, or your headlights are cloudy, those drives get a lot more tiring than they need to be.

The good news is most of this is easy to fix at home. Here's what I do and what I tell people to check before the darkest part of the year.

Start with the inside of the windshield

This is the one almost everybody skips. The inside of your windshield builds up a film over time from the dash plastics, the HVAC system, and just breathing in the car. In daylight you barely notice it. At night, that film catches every oncoming headlight and turns it into a big smeary glow.

How to clean it without streaks

• Use two clean microfiber towels: one to clean, one to dry and buff.

• Spray the glass cleaner onto the towel, not the windshield, so it doesn't drip onto your dash.

• Wipe in straight lines, side to side, then go over it again top to bottom with the dry towel. If you see streaks, you can tell which direction they're coming from.

• The bottom corners by the dash are the hardest to reach. Flip the towel over the back of your hand and get in there.

If your windows fog up the second you get in the car, that's usually extra moisture inside, not just dirty glass. I wrote a whole post on that one: How to Keep Your Car Interior Dry and Fresh Through a Wet Winter.

Then the outside glass

The outside of the windshield picks up road film, tree sap, and the oily spray coming off other cars. That film is why your wipers sometimes chatter or leave a hazy arc even with new blades.

A normal wash doesn't always get it off. Here's a good test: after washing, run your fingertips across the dry glass. If it feels gritty or draggy instead of smooth, there's still stuff bonded to it. A clay bar takes that off really well, same as it does on paint. It's part of how I prep a car on a Level 1 detail.

Rain repellent makes a big difference

Honestly, this is one of my favorite things for Pacific Northwest driving. A rain repellent on the outside glass makes water bead up and roll off instead of sheeting across the windshield. At highway speed a lot of it just blows off, and the wipers have way less work to do. At night it cuts down on that blurry glare you get when the glass is covered in a layer of water.

You can buy rain repellent at any auto parts store and put it on yourself. The key is getting the glass completely clean first, or it'll lock in the film and streak. Rain repellent on the exterior windows is included in my Level 2 detail, so if you're booking one anyway, that part's covered.

Wipers: cheap fix, big difference

Wiper blades take a beating here. Between the summer sun drying out the rubber and months of rain, they wear out faster than people think.

Signs it's time for new blades

• Streaks or lines that stay on the glass after a swipe

• Chattering or skipping across the windshield

• Spots the blade misses completely

• Rubber that looks cracked, torn, or stiff

Make them last longer

• Wipe the rubber edge with a damp towel every time you wash the car. You'll be surprised how much black gunk comes off.

• Don't run them on a dry or icy windshield. Use washer fluid first, or let the defroster do its thing.

• Keep the washer fluid topped off. Running out on a dark, misty night on SR-520 is no fun.

New blades are inexpensive and usually take a few minutes to swap. If yours are more than a year old and you're already noticing streaks, I'd just replace them before winter.

Cloudy or yellow headlights

A lot of cars on the road have headlights that look foggy or yellow. Most headlight lenses are plastic, and over time the sun and road grime break down the clear outer layer. It looks bad, but the bigger deal is that it scatters the light, so less of it actually lands on the road in front of you.

What you can do

• Keep them clean. Dirt and road film on the lens cut the light down too, so give them a real wash, not just a quick spray.

• Check them at night against a garage door or wall. If the beam looks dim, blotchy, or there's no clear cutoff line, the lens is probably part of the problem.

• Light haze can sometimes be improved with a DIY headlight kit. Go slow and follow the steps, especially the sanding part.

• Once they're clear, protect them. A ceramic coating goes on almost every surface: paint, plastics, glass, headlights. That helps keep the lenses from going cloudy again as fast.

If you're not sure whether your headlights can be brought back, I'm happy to take a look when I'm out doing your car.

Mirrors and side windows count too

When you change lanes in the rain at night, you're relying on your side mirrors and side windows. They get the same road film as the windshield, but nobody thinks about them.

• Clean the side mirrors and the side windows, inside and out.

• Roll each window down a couple inches and wipe the top edge. That strip collects dirt and leaves a line on the glass every time you roll the window back up.

• If you're putting rain repellent on, do the side windows and mirrors too. Water clears off them a lot faster.

A quick monthly glass check

Here's what I'd do once a month through winter. It takes about fifteen minutes:

1. Clean the inside of the windshield with two towels.

2. Wash the outside glass and wipe the wiper edges.

3. Top off the washer fluid.

4. Check the headlights at night against a wall.

5. Clean the mirrors and the top edges of the windows.

None of this is complicated, but it makes those dark commutes a lot less stressful.

Want me to handle it?

If you'd rather not deal with it, every detail I do includes the windows cleaned inside and out, and the Level 2 adds rain repellent on the exterior glass. You can see what's in each package on my pricing page. I'm fully mobile and come to you anywhere around Kirkland, Bellevue, Redmond, and the rest of the Eastside.
