Real Evidence
This page documents what most diners never see: PTFE-coated fiberglass release sheets that are worn, overheated, or improperly cleaned on clamshell grills. When these sheets fray, fiberglass fibers and degraded coating can shed where food is prepared. That doesn’t belong anywhere near your burger or chicken.
We’re showing it clearly, so brands can fix it quickly.
The two photos clearly show how damaged how damaged sheets expose harmful fiberglass to your food.
Industry Coverage: Total Food Service has covered this problem and the simple path forward.
The following video shows a damaged release sheet on a clamshell grill. The dark PTFE-coated fiberglass sheet shows frayed, white strands at the edge as the press closes on burgers - exactly where loose fibers can transfer if the sheet isn’t replaced on time.
Our Demands
(simple, immediate, verifiable)
Disclose
Tell customers and employees if fiberglass release sheets are in use.
Publish a timeline
Share a public phase-out plan and progress updates immediately.
Replace
Swap the sheet! Move to non-fiberglass liners that do the same job without woven glass.
Maintain & train
Until the swap is complete, follow strict temperature limits and replacement schedules to prevent fraying.
The Problem and What We’re Demanding
Fast food chains are pressing your meal between PTFE-coated fiberglass sheets on two-sided clamshell grills. When these sheets are overheated, overused, or cleaned the wrong way, they fray, and that means fiberglass fibers can end up where food is prepared and served. Fiberglass is a respiratory and skin irritant and not meant to be ingested. It does not belong anywhere near your burger or chicken.
This isn’t a fringe issue. These sheets are a standard consumable in many fast-food kitchens, yet customers aren’t told, and there’s no clear public policy from most brands on phasing out fiberglass-based liners or even disclosing their use. That’s unacceptable!
We’re a consumer action group and we’re done with restaurants quietly putting our health at risk. We’re shedding light on a real, fixable problem and demanding accountability.
Momentum Is Building!
More than 15,000 consumers have already signed the petition to Keep Fiberglass Out of Fast Food
The Keep Fiberglass Out of Fast Food campaign is working.
Thanks to the voices of thousands of consumers, Freddy’s Frozen Custard & Steakburgers has announced that it is working with its grill manufacturer, AccuTemp, to explore fiberglass-free release sheet options.
This is an important step in the right direction and a clear sign that companies are listening.
This progress happened because people spoke up.
More than 15,000 consumers have already signed the petition to Keep Fiberglass Out of Fast Food, sending a clear message to the fast-food industry: customers do not want fiberglass anywhere near their food. When consumers learn that fiberglass materials may be used in the cooking process, they overwhelmingly agree that safer, fiberglass-free alternatives should be used instead.
But our work isn’t finished yet.
While Freddy’s willingness to explore fiberglass-free options is encouraging, we need real change across the entire quick-service restaurant industry. That means moving away from fiberglass cooking materials and committing to safer alternatives.
The growing support behind this campaign shows that consumers care deeply about how their food is prepared.
Fast-food companies should listen.
We must keep the pressure on.
We will continue raising awareness, growing the petition, and calling on quick-service restaurants and equipment manufacturers to adopt fiberglass-free cooking solutions.
Because at the end of the day, the goal is simple:
Our food should be free of fiberglass.
