If you're looking for a conveyor belt cleaner, you're choosing between five approaches. They are not interchangeable. They do different jobs, they cost different amounts of labor, and three of the five leave behind the exact thing your swabs are looking for.
Here's the honest comparison, including where our own equipment does not apply.
The short version
- Sanitize, but leave the biofilm: foamers, steamers, belt scrapers
- Remove the biofilm, but cost you the labor: hand scrubbing
- Both, without the labor: mechanical belt scrubber
The split that matters is biofilm. Everything in the first group is solving a different problem than the one failing your swabs.
1. Belt scrapers and wipers
A blade or wiper mounted against the belt, knocking off carryback while the line runs. Common on aggregate and bulk handling, less so in food.
What it does: removes loose debris continuously, no labor.
Where it fails: it's a bulk-removal device, not a sanitation device. It doesn't touch attached soil, it doesn't break up biofilm, and it introduces a wear point in contact with your product-contact surface. Useful for keeping a line running clean. It is not part of your sanitation program.
2. Foamers
Clinging foam applied across the belt, dwell time, then rinse.
What it does: excellent chemical coverage and contact time. Kills what it reaches.
Where it fails: foam has no mechanical energy. Biofilm is held together by an extracellular polymeric substance, a polysaccharide matrix the organisms build specifically to resist chemical attack. Chemistry alone doesn't lift it off the belt. You can foam a belt correctly, rinse it correctly, and still swab high, because what's left is a matrix that shielded the organisms underneath it.
This is the most common gap we see. It isn't a chemical concentration problem or a crew problem. Foam sanitizes. It doesn't remove.

3. Steamers
High-temperature steam applied to the belt surface.
What it does: thermal kill, no chemical residue, reaches some geometry that foam runs off.
Where it fails: same structural problem as foaming, plus two of its own. Steam kills organisms it contacts but leaves the biofilm matrix in place, and that matrix is what the next shift's organisms colonize. Steam also drives moisture and heat into a room you're usually trying to keep dry and cold, and it's slow across a fifty-foot belt.
4. Hand scrubbing
Someone on their knees with a pad and a bucket, working the belt in sections.
What it does: this actually works. Mechanical agitation plus chemical is the combination that removes biofilm, and a person with a scrub pad delivers exactly that.
Where it fails: it's the most expensive method you have, and the least consistent. One belt can eat a large share of the sanitation window. Two workers scrubbing the same belt apply different pressure, spend different time, and cover the surface differently, and that variance shows up in your swab results. It also puts a worker on their knees next to equipment on a wet floor. And the sections that get the least attention are the ones nobody can reach comfortably, which are the same sections that show up in environmental monitoring.
Most plants know hand scrubbing works. The reason they're searching for a conveyor belt cleaner is that they can't afford to keep doing it.
5. Mechanical belt scrubbers
A unit sits on the belt during sanitation. The belt runs, the unit stays put, and the belt pulls itself across a stationary scrub pad while cleaning solution is metered onto the surface.
What it does: delivers both halves of the job. Mechanical agitation from the pad against belt motion, plus chemical delivery, across the full belt width, at the same pressure on every pass. It's hand scrubbing without the hands, and it doesn't get tired at the end of the belt.
Where it fails, honestly: it runs during your sanitation window, not during production. It needs a belt that can be run while the line is down. And it's equipment, so there's a purchase decision that a case of chemical doesn't require.
What this looks like in practice
Brite Belt is the mechanical option in that last group. Two things worth knowing before you compare us to anyone else:
Industry recognition, not a testimonial. Brite Belt is listed in the Western Growers LGMA Appendix S document, Table 3 on page 22, as a recommended conveyor belt scrubber. That's a compliance reference document, not a customer quote.
It's not new. The first units went into a USDA facility in 1995. The BRICK scrubber was introduced in 2016. Over 10,000 conveyor belts cleaned, still made in the USA.
If you run a mechanical scrubber, run it right
The equipment only does its job if the process around it holds up. Five things we tell every customer, and the reasons behind them:
Assign one unit per belt. Cross-contamination between belts is a real risk. Label each scrubber and assign it to a specific belt. It supports traceability and it stops you from moving organisms between lines with your own equipment.
Use heated solution when you can. For roughly every 20°F increase in cleaning solution temperature, you approximately double the chemical cleaning strength. Heat plus mechanical action is the strongest combination available for biofilm removal on a belt surface.
Treat pads as single-use in CCP areas. In Critical Control Point areas, discard the pad after each use. A pad that has collected biofilm and organic material from one belt carries it onto the next.
Empty the reservoir after every use. Storing a unit filled with cleaning solution distorts the polyethylene housing over time and leaves residual chemistry degrading the pad and components.
Verify with ATP, before and after. Before-and-after swabbing is the only reliable way to know your process is actually removing biofilm rather than just moving it around. RLU readings give you objective data on what the process achieves and where it doesn't.
None of this is complicated, and none of it is optional. Contact time is the variable that matters most, and it's the first thing that gets cut when the sanitation window runs tight. A scrubber that only gets half its cycle is doing half the job.
How to choose
Ask what each option removes, not what it kills.
- If you need carryback control while the line runs, use a scraper. It's not a sanitation tool.
- If you need chemical kill and good coverage, foamers and steamers do that well. Keep them.
- If your swabs come back high on belts you just cleaned, the gap is mechanical, and adding more chemistry won't close it.
- If you're closing that gap with labor today, the question is only whether you keep paying for it in hours or replace it with equipment.
Most facilities we work with don't rip anything out. They add the mechanical step to what they already run, because the foamer and the scrubber are doing different jobs.
