Clean and Adjust Spotlights and Under-Cabinet Lighting Like a Pro

Good lighting can transform a kitchen from purely functional to warm and inviting. But over time, spotlights and under-cabinet fixtures collect dust, grease, and grime, and their angles can shift so the light no longer falls where you need it. The good news? With a few simple steps, you can clean and adjust your lighting like a professional—no electrician required.
Here’s a step-by-step guide tailored for Canadian homes.
Start with Safety
Before you do anything, turn off the power to the lights you’ll be working on. Unplug the fixture if possible, or switch off the appropriate breaker in your electrical panel.
Wait a few minutes for bulbs to cool down before touching them. LED and halogen bulbs can get quite hot, and you don’t want to risk a burn.
Remove Dust and Grease the Right Way
Kitchen lighting tends to get greasy, especially near the stove or range hood. Use a soft microfiber cloth slightly dampened with warm water and a drop of mild dish soap. Avoid harsh cleaners or abrasive pads—they can damage finishes and lenses.
- Glass and reflectors: Wipe gently with a damp cloth, then polish with a dry, lint-free one.
- Metal or chrome surfaces: A bit of vinegar diluted in water can cut through grease, but be careful not to let moisture seep into the fixture.
- Recessed spotlights: If the glass cover can be removed, clean it separately and handle the socket area with care.
A vacuum with a brush attachment is handy for removing dust from tight corners before wiping down surfaces.
Check the Bulbs—and Boost Efficiency
While you’re at it, check that all bulbs are working properly. Even LEDs can lose brightness over time without completely burning out.
Consider upgrading to high-quality LED bulbs if you haven’t already. They use less energy, last longer, and provide better colour rendering. For a cozy kitchen atmosphere, choose a colour temperature around 2700–3000 kelvin—a warm white that flatters both food and décor.
Adjust Angles for the Best Light
Small adjustments can make a big difference. Most spotlights can tilt or swivel, allowing you to direct light exactly where you need it.
- Over countertops: Aim the beam so it illuminates the work surface without creating glare.
- Near the sink or stove: Angle the light slightly forward to reduce shadows and improve visibility.
- Under cabinets: Adjust fixtures so the light spreads evenly across the counter, avoiding dark spots.
If you have multiple spotlights in a row, overlap their light beams slightly for a smooth, consistent look.
Consider an Upgrade
If your lighting setup is more than a decade old, it might be time for an upgrade. Modern LED systems offer better brightness, colour accuracy, and energy efficiency.
Look for integrated LED panels with a high colour rendering index (CRI 90+). They make food look more natural and vibrant. Many models are also dimmable, letting you switch from bright task lighting to a softer evening glow with ease.
Make It a Routine
Once your lights are clean and properly adjusted, keep them that way with a simple maintenance routine:
- Wipe down fixtures when you do your regular kitchen cleaning.
- Check that all bulbs are still shining evenly.
- Re-adjust angles if you’ve moved appliances or changed your kitchen layout.
A few minutes of care every few months will keep your kitchen bright, efficient, and welcoming—just like a pro’s.
