DOFF Cleaning vs Laser Cleaning
DOFF cleaning and laser cleaning are both used on sensitive surfaces, but they are not the same tool. DOFF uses high-temperature low-volume water or steam, while laser cleaning is a dry, highly targeted process. The right choice depends on the contamination, the substrate and the finish required.
Where DOFF often works well
Biological growth, general surface soiling, light atmospheric dirt and some facade cleaning situations where heat-assisted moisture is acceptable.
Where laser cleaning can be stronger
Paint removal, localised coating removal, soot, oxidation and deposits where highly selective dry cleaning is preferable to steam or hot water.
Mess, moisture and containment
DOFF introduces heat and moisture to the substrate. Laser cleaning is dry, which can be attractive on interiors, around certain finishes or where runoff management is awkward.
Surface refurbishment potential
Where the brief extends beyond washing and into surface preparation, coating removal or very selective restoration, laser cleaning may offer a more refurbishment-focused capability than a steam-based cleaning method.
Balanced conclusion
DOFF remains valuable, especially in conservation cleaning, but where clients need cleaner edges, reduced mess, less saturation or more precise removal, laser cleaning can compare very favourably.
