Before Treatment
When examining the contaminated Nylon surface at 1000x, you see dirt particles scattered across the fibers, creating a bumpy, uneven layer. Grime clings tightly to the edges, dulling the material's natural weave and hiding finer details. This buildup makes the whole texture look rough and obscured.
After Treatment
After laser treatment, the Nylon surface appears completely clear and smooth under 1000x view. Fibers stand out evenly now, without any clinging residues or rough spots. The clean finish

Nylon Laser Cleaning Laser Cleaning FAQs
Q: How can I laser clean Nylon without causing melting?
A: I've seen Nylon respond well to gentle laser passes that target surface grime first. Start by scanning the area slowly to loosen dirt without building up too much heat in the material. This approach keeps the Nylon's surface intact while removing contaminants effectively, as the plastic tends to soften under prolonged exposure.
Q: What are the best practices for laser cleaning dirty Nylon gears?
A: When cleaning Nylon gears, begin with a low-intensity sweep to test the material's reaction. Follow up with focused bursts on stubborn spots, always moving the laser steadily to avoid hot spots. In my experience, this method restores the gears' smooth operation without compromising their flexibility or strength.
Q: Why does Nylon sometimes discolor during laser cleaning, and how to fix it?
A: Nylon can pick up slight discoloration if the laser lingers too long on one area, drawing out underlying pigments. To fix this, reduce dwell time and incorporate short cooling intervals between passes.
