Laser cleaning questions, answered

Laser cleaning uses short pulses of laser light to remove rust, coatings, carbon, grease and other buildup from a surface. The settings are adjusted to the material so the buildup comes off and the surface underneath is preserved as much as possible. It's a non-contact process, so there's no blasting media or chemical stripper involved.

The laser itself uses no chemicals and no blasting media. The removed material becomes fumes and fine particles, which are pulled away by fume extraction at the work point. Food-contact parts still get a normal wash, rinse and sanitize afterward.

It can if the settings are wrong. Too much power, too much overlap or repeated passes can roughen a surface or leave heat tint on stainless steel (PMC study on 304L stainless). That's why every job starts with a test spot and settings matched to the material.

Plastics, most rubber and clear glass are usually poor candidates, and deep cavities the beam can't see are out of reach (Tri-State Laser Cleaning). Laser cleaning also removes cast-iron seasoning, so seasoned surfaces have to be re-seasoned. If another method fits the job better, we'll say so.

For baked-on carbon on metal parts, a laser can remove buildup without soaking the area or producing greasy wash water. Pressure washing is cheaper for large, simple surfaces, but grease-laden wash water has to be kept out of storm drains (Nashville stormwater guidance). The right answer depends on the item and what's on it.

Laser cleaning is used on metal kitchen equipment with baked-on carbon and grease, such as grill grates, flat tops, burners, fryer and oven exteriors, racks and hood filters. Every item gets a test spot first. Plastic parts, gaskets and anything the beam can't reach are left alone.

Laser cleaning removes buildup but does not sanitize. Any food-contact part is washed, rinsed and sanitized according to your local health code before it goes back into service, as the FDA Food Code requires for food-contact surfaces. Fume extraction captures the removed material during the work.

Full hood, duct and exhaust-fan cleaning under NFPA 96 is a separate service done by exhaust cleaning companies, and many areas require a certified provider. ArcLight's demo scope is equipment buildup, including removable parts like baffle filters. Demo placeholder confirm whether ArcLight does any exhaust work or refers it out

NFPA 96 sets inspection for grease buildup at monthly for solid-fuel cooking, quarterly for high-volume cooking such as 24-hour, charbroiling or wok, semiannually for moderate volume, and annually for low volume such as churches and seasonal businesses (Markel summary of NFPA 96). Cleaning is required when the inspection finds grease buildup. Your local fire code may be stricter.

Under the FDA Food Code, food-contact surfaces used with time/temperature-controlled food are cleaned at least every 4 hours, and food-contact surfaces of cooking and baking equipment at least every 24 hours (FDA Food Code 2022, 4-602.11 and 4-602.12). Your state or county adopts its own version, so check the local code.

The aim is to work around service, before opening, after close or on a slow day, so the line is ready for the next shift. Equipment has to be cool and the work area cleared of staff while the laser runs. Demo placeholder ArcLight's actual scheduling hours and typical time per item

Yes. Laser cleaning strips cast iron to bare metal, seasoning included (Pristine Laser Restoration), so seasoned grates or plancha tops need re-seasoning afterward. If you want to keep the seasoning, a laser is the wrong tool for that surface.

It's safe when the work area is controlled. Industrial cleaning lasers are typically Class 4, which means eye, skin and fire hazards, including from reflected light (Laser Institute of America). Staff stay out of the marked area, the operator wears laser-specific eye protection, and fume extraction runs at the work point.

It's turned into fumes and fine particles, which have to be captured. OSHA lists local exhaust ventilation as a control for laser-generated airborne contaminants (OSHA), so extraction runs at the work point the whole time. Demo placeholder ArcLight's extraction and filtration equipment

Yes, with the right settings. Stainless can be cleaned without grinding or scratching, but too much heat input can cause discoloration (heat tint) and affect corrosion resistance (PMC study). We test a small spot and check the finish before doing the whole piece.

It depends on the item, how much buildup is on it, and access. ArcLight quotes after an assessment, and this demo site shows no prices. Demo placeholder how ArcLight prices work, e.g. per visit, per item or per program

Buildup is easier to remove before it's baked on in layers, and inspections go smoother when nothing has been left to pile up. The FDA Food Code expects nonfood-contact surfaces to be cleaned "at a frequency necessary to preclude accumulation of soil residues" (FDA Food Code 2022, 4-602.13). A program puts that on the calendar.

Each visit should leave you a dated record of what was cleaned and the condition found, with before-and-after photos. A dated record is easy to hand an inspector or a manager who asks when something was last cleaned. Demo placeholder sample ArcLight service report
