Does Laser Cleaning Really Work?
Why Laser Cleaning Is Changing the Game in Surface Restoration
The most commonly asked question we receive at Merritt Industrial surrounding our laser cleaning services is ‘does it work like the videos I’ve seen on Youtube?” While you have to be mindful that most videos are only published when they yield fast, visually aweing results, the general answer here is yes. Laser cleaning is a fast, safe alternative to sandblasting or other media blasting methods. Unlike sandblasting for rust or paint removal, our laser cleaning provides limited zero secondary waste with virtually the same removal rate with a much smaller footprint.
Laser cleaning uses high-intensity light to ablate surface contaminants like rust, paint, and grime—without harming the underlying material. It’s ideal for surfaces where precision, cleanliness, and safety are critical.

Sandblasting vs. Laser Cleaning: Why Media Contamination and Hidden Costs Matter
Sandblasting may seem like a lower-cost option up front, but it introduces abrasive media into the surface — especially on rough or porous materials like brick, block, and concrete. That grit is hard to remove, often requiring additional cleaning steps before painting or coating. Laser cleaning, by contrast, uses no media at all. It leaves behind a dry, bondable surface that’s free of embedded contaminants — making it the ideal prep method when coating performance and cleanliness matter.
What Does Industrial Sandblasting Really Cost?
While sandblasting appears cost-effective at first glance, it often comes with hidden labor and cleanup costs.
Average Hourly Rates for Industrial Sandblasting:
$100–$150/hour – Standard sandblasting (labor + equipment)
$150–$200/hour – Specialty blasting (e.g., confined spaces, recovery systems)
$20–$40/hour – Abrasive media cost (e.g., silica, garnet, slag)
These numbers don’t include the additional man-hours required to clean up media, tarp the area, or remove contaminants embedded in rough surfaces etc. Sandblasting can be very aggressive and can creates high surface tension that can damage delicate surfaces creating expensive repair costs.
Risks of Embedded Media:
Coating failure due to poor bonding on contaminated surfaces – Read more about poor surface prep here
Ongoing fallout from trapped grit affecting nearby workers or finishes
Compliance issues in food-grade or clean manufacturing environments
Extra cleanup steps, increasing job cost and duration
The Laser Cleaning Advantage: No Grit. No Waste. No Problem.
Laser cleaning eliminates all of the above mentioned sandblasting issues by using light instead of media.
It vaporizes surface contaminants (rust, paint, grease) without introducing foreign matter
The process is dry, chemical-free, and non-abrasive
No grit gets lodged in pores or crevices
Surfaces are left clean, smooth, and ready to coat — with no secondary waste
This makes laser cleaning ideal for:
Delicate substrates
Precision work
Environments where cleanliness and adhesion matter most
Bottom Line: Consider Total Cost — Not Just Hourly Rates
A surface covered in residual grit isn’t ready to coat — it’s a liability.
A laser-cleaned surface? It’s dry, media-free, and built for performance.
While hourly rates for laser cleaning are often comparable to sandblasting, the reduced cleanup, increased surface integrity, and lack of media contamination make it a smarter long-term choice — especially for coating prep, restoration, or historic preservation.
