How to Clean a Laser with a Honeycomb Bed

The use of a modern laser cutter requires not only craftsmanship but responsibility and a will to put in the extra work to ensure that things go smoothly. Like many complex machines, a laser cutter requires a fair bit of maintenance from time to time.

If you operate a laser cutter that uses a honeycomb table, you will find cleaning the table a bit problematic with regard to the supplies you need, the preparation, and of course, the cleaning effort. In that regard, it pays to be well-prepared before you actually need to do it.

Over the next few minutes, we’ll talk you through how to clean a laser with a honeycomb bed including the preparation process, the supplies you need, and what exactly you should expect when cleaning a laser cutter with a honeycomb bed. Believe it or not but the process is actually a lot easier than people imagine.

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

How to clean a laser with a honeycomb bed

Supplies

First and foremost, you’re going to need to prepare a few things to make sure everything goes smoothly. A honeycomb table can get quite messy over time if it’s used often, so having the right supplies on hand is paramount.

In short, you want to get your hands on the following:

• Pressure Washer (If you don’t have one, then we would recommend the Westinghouse WPX2300e Electric Pressure Washer on Amazon)
• Simple Green All Purpose Cleaner on Amazon (Optional for stubborn resin)

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.

Disassemble the Bed

Once you have assessed the damage and you have your supplies on hand, you should proceed with removing the laser cutter bed as carefully as you possibly can. Although these things are quite sturdy, there is always the risk that you might damage a pin, a screw, or the tray itself.

• Remove the pins. This should be pretty straightforward. The easy-to-remove bed is usually held by a few push pins that you should be able to remove without using any additional tools.
• Check for screws. Although not that common, some honeycomb beds may be held in place by additional screws. See if this is the case before forcing the bed off. 
• Watch out for bends. If you’re dealing with an aluminum laser bed, you should make sure that you don’t accidentally bend the bed when you take it off. Provided that you took all the pins and screws off, this shouldn’t be too much of a problem.
• Remember what goes where. It’s easy to get confused when you have to put the whole thing back together again so make some mental notes about the exact position of the bed and make sure not to lose any of the screws.

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

Pre-Treat with Cleaner (Optional)

• Spray the honeycomb bed with diluted Simple Green All-Purpose Cleaner (only use for stubborn resin that wont come off with pressure washing)
• Let it sit for 5–10 minutes to break down stubborn resin and soot.
• Avoid strong corrosive chemicals that can damage the honeycomb’s metal.

Set Up the Pressure Washer

• 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.
