Laser Cleaning Vs. Traditional Methods
| Cleaning Method | How it Works | Key Limitations Vs. Laser Cleaning |
|---|
| Abrasive Blasting | Media (sand, grit, glass beads) propelled at high velocity | Creates dust and waste, requires consumables, can damage delicate substrates, needs masking |
|---|
| Mechanical Scraping / Brushing | Physical contact (wire brushing, grinding, scraping) | Labor-intensive, scratches/deforms surfaces, inconsistent, poor for complex geometries |
|---|
| Chemical Cleaning | Solvents or acids dissolve contaminants | Hazardous waste, health risks, longer processing time, possible substrate attack |
|---|
| Ultrasonic Cleaning | Cavitation in liquid bath removes contaminants | Tank size limits, uses chemicals, no selective cleaning, not line-integrated |
|---|
| Dry Ice Blasting | CO₂ pellets sublimate and lift contaminants | Requires dry ice supply, messy, less precise, weak on thick rust/coatings |
|---|
| Thermal Cleaning | High-temperature ovens burn off residues | High energy use, long cycles, risk of oxidation/warping, emission controls needed |

Laser Cleaning vs. Abrasive Blasting
Abrasive blasting removes contaminants by propelling media such as sand, grit, or glass beads at high speed. While effective, it generates dust and waste, can damage sensitive substrates, and often requires manual masking to protect surrounding areas.
Laser Cleaning vs. Mechanical Scraping or Brushing
Mechanical methods like wire brushing, grinding, and scraping require physical contact to remove contaminants. These processes are also labor-intensive and can scratch or deform the substrate. In addition, they don’t work well for complex geometries or when consistency is important.
Laser Cleaning vs. Chemical Cleaning Methods
When solvents or acids are used to dissolve contaminants, it generates hazardous waste. This can pose health and safety risks to workers and may alter substrates. Chemical cleaning often means longer processing times, including multiple rinses after cleaning.
Laser Cleaning vs. Ultrasonic Cleaning
Ultrasonic cleaning uses high-frequency sound waves in a liquid bath to remove contaminants through cavitation. While gentle and effective for small parts, it is difficult to scale for selective cleaning or in-line production. Chemical solutions also require handling and proper disposal.
Laser Cleaning vs. Dry Ice Blasting
Dry ice blasting uses frozen pellets that sublimate on impact to lift contaminants without abrasion. While non-toxic and residue-free, it requires a continuous dry ice supply, can be messy, and lacks the precision needed for selective cleaning. It is also less effective on thick rust or heavy coatings.
Laser Cleaning vs. Thermal Cleaning
Thermal cleaning removes organic coatings and residues by heating parts to high temperatures. While effective for heavy buildup, it requires long cycle times, consumes significant energy, and can cause oxidation or substrate distortion. Emissions may also require additional environmental controls.
