Why You Need to Clean a Laser with a Honeycomb Bed

• Better airflow – A clogged honeycomb restricts ventilation, leading to more smoke and uneven cuts.
• Improved cut quality – Resin and debris buildup can cause burning, discoloration, and even unwanted marks on the underside of your material.
• Longer equipment life – Regular cleaning prevents corrosive buildup and keeps your laser system operating efficiently.
• Fire safety – Loose debris or resin can catch fire if not removed regularly.

Cleaning Methods for a Laser Honeycomb Bed

Method	How It Works	Pros	Cons
Vacuuming / Brushing	Use a shop vac, small brush, or compressed air to remove dust and light debris.	– Quick and easy – No water or chemicals needed – Low risk of damage	– Doesn’t remove resin buildup – Needs frequent repetition
Wiping with Cleaner	Spray with a mild cleaner (e.g., Simple Green) and wipe with a cloth or sponge.	– Good for light soot and resin – Low cost – Can be done inside the machine	– Time-consuming – Hard to reach inside honeycomb cells
Soaking in Cleaner	Remove honeycomb, soak in warm water + Simple Green or degreaser, then rinse.	– Loosens stubborn resin – Even cleaning coverage – Minimal scrubbing needed	– Requires removal of honeycomb – Long drying time – May leave residue if not rinsed well
Pressure Washing	Medium-pressure washer (1200–1500 PSI) flushes out resin and debris.	– Deep cleans resin buildup – Restores honeycomb like new – Fast once set up	– Must remove honeycomb – Risk of bending if pressure too high – Requires outdoor space & drying time

Supplies

Having the right cleaning supplies makes the job much easier.

Recommended tools:

Tool	Purpose
Lint-free cloths	General cleaning
Isopropyl alcohol	Removing residue
Soft nylon brush	Scrubbing cells
Plastic scraper	Removing stuck debris
Vacuum or compressed air	Dust removal
Simple Green All Purpose Cleaner	Heavy buildup
Rubber gloves	Hand protection

Avoid steel brushes or abrasive metal tools that can damage coatings or bend the honeycomb structure.

Assessment

The next thing you want to do is to inspect the honeycomb bed and figure out exactly how much cleaning it requires. Needless to say, the cutting process can get quite messy, and so does the cleaning effort afterward.

Even if you use the laser cutter sparingly, the machine will still accumulate a lot of soot, smoke, grime, and everything else that might gradually build up over time. As such, you want to closely inspect the laser cutter bed to figure out how to proceed.

How To Clean a Laser with a Honeycomb Bed: Cleaning Process

Step 1: Remove Loose Debris

Start by removing large debris from the honeycomb surface.

Use:

• A handheld vacuum
• Compressed air
• Soft brush

Pay attention to corners where dust tends to collect.

If using compressed air, use moderate pressure to avoid forcing debris deeper into the machine.

Step 2: Remove the Honeycomb Bed

Most honeycomb beds are removable.

Take the bed out carefully and place it on a protected work surface.

Removing it makes deep cleaning much easier and prevents residue from spreading inside your machine.

Step 3: Scrape Off Heavy Residue

Laser cutting resin-heavy materials like MDF or acrylic often leaves hardened buildup.

Use a:

• Plastic scraper
• Old credit card
• Nylon scraper

Avoid metal putty knives unless absolutely necessary.

Be gentle to avoid bending the honeycomb cells. We recommend using these plastic scraper tools, which make the job so much easier.

Step 4: Apply Cleaning Solution

For moderate to heavy buildup, spray the honeycomb bed with:

• Diluted Simple Green All Purpose Cleaner

Allow the cleaner to soak for several minutes before scrubbing.

This softens resin and soot buildup.

Step 5: Scrub the Honeycomb

Use a soft nylon brush to clean between the honeycomb cells.

Work slowly and methodically.

The dirtiest areas are usually:

• Near frequent cutting zones
• Around the center of the bed
• Areas with poor airflow

For stubborn spots, repeat the soak-and-scrub process.

Step 6: Rinse and Dry Thoroughly

Rinse the honeycomb carefully and allow it to dry completely before reinstalling.

Moisture left behind can:

• Cause rust
• Damage electronics
• Affect airflow
• Lead to corrosion

Air drying or compressed air can help speed up the process.

Step 7: Use a Pressure Washer If Required (For Stubborn Residue)

• Use a medium-pressure setting (around 1,200–1,500 PSI) — strong enough to clean but not so powerful that it bends the honeycomb grid.
• A wide-angle spray nozzle (25°–40°) is best for even cleaning.

Pressure Wash the Honeycomb Bed

• Hold the spray wand at a distance of 12–18 inches from the surface.
• Work in smooth passes across the honeycomb to flush out resin, soot, and trapped debris.
• Flip the honeycomb over and repeat on the other side for a deep clean.

Rinse & Inspect

• Rinse thoroughly with clean water to remove any cleaner residue.
• Check for areas with persistent buildup and repeat if needed.

Dry Completely

• Shake off excess water and let the honeycomb air dry fully before reinstalling.
• To speed things up, use compressed air or leave the honeycomb in the sun for a few hours.

Pro Tips:

• Never use a high-pressure, narrow jet nozzle too close to the honeycomb — it can warp the thin metal cells.
• Always dry the honeycomb thoroughly to prevent rust or corrosion.
• Regular light cleanings (vacuum + wipe down) will reduce the need for frequent pressure washing.

Why Having a Clean Laser Cutter Bed is Important

For a laser cutter to operate at optimal parameters, the machine needs proper cleaning and maintenance on a regular basis. Anything short of that would render the processing of the flat material largely ineffective by most standards.

Those of you who have used laser cutting machines in the past would know that these devices are very accurate and that the carving/cutting process causes the build-up of a lot of grime and soot.

Failure to properly care for the machine will render the cutting process ineffective and even hazardous, especially if you’re cutting wood. Affected by the heat, any soot present on the bed will cause you to get an unclear engraving or damage the whole piece altogether.

Not just that but proper maintenance also reduces the risk of damage to the machine and/or health hazards to the operator. If you find that even after a thorough cleaning the honeycomb still contains ingrained grime then it may be time to consider purchasing a new honeycomb table.

Pro Tips for Maintaining a Clean Honeycomb Bed

• Use masking tape or transfer tape on materials to minimize resin deposits.
• Add sacrificial layers (MDF, cardboard, or acrylic sheets) under projects to catch excess soot and resin.
• Vacuum after every session to prevent buildup from hardening.
• Rotate your honeycomb if possible, to extend its lifespan.

What to Avoid When Cleaning a Laser with a Honeycomb Bed

It is important to see the laser cutting machine as a manufacturing tool first and foremost. In that regard, you shouldn’t employ any tools or supplies that might interfere with the machine’s capacity to perform its task in the long run.

We mainly advise you here to avoid scrubbing any of the components that interact with the material and the laser beam, but you should keep this in mind when dealing with the bed as well. Know that simple scratches to the honeycomb bed will negatively affect the machine’s overall effectiveness.

At the same time, some cleaning agents may also damage the bed of the machine, especially those that are too oily or greasy. Instead, you should look into using diluted cleaning solutions like Simple Green along with water and nothing else.

Also, try to remember that the material construction of the bed itself determines which type of cleaning supplies you may or may not use. While hard beds may allow for harsher scrubbing, a soft aluminum bed will definitely get damaged by hard brushes and persistent scraping.

How Often Should I Clean A Laser With a Honeycomb Bed?

• Light users (occasional engraving): Once every 1–2 months.
• Frequent users (daily cutting): Every 1–2 weeks.
• Business use (production): Weekly or even daily, depending on workload.

Conclusion

A clean honeycomb bed makes a big difference in cut quality, airflow, and overall machine performance. By following simple cleaning routines, you’ll prevent buildup, extend the life of your bed, and ensure every project comes out sharp and professional.
