If you’re reading this, chances are you work in a lab, manufacturing facility, or industrial space that relies on TPE tubing. As someone who’s spent the last 12 years supplying TPE tubing to industries ranging from biopharmaceutical manufacturing to food and beverage processing, I’ve seen firsthand how easy it is to overlook a simple but critical step: proper TPE tubing cleaning. Too many teams write off their tubing as “disposable” or use generic cleaning protocols designed for rubber or PVC, and that’s where problems start. TPE (Thermoplastic Elastomer) is a versatile material—flexible, chemical-resistant, and durable—but it’s not indestructible. Clean it wrong, and you’ll end up with compromised product purity, shortened tubing lifespan, or even contamination that derails entire production runs. TPE Tubing
Today, I’m breaking down exactly how to clean TPE tubing correctly, based on years of hands-on experience with our clients’ needs and the science of TPE material properties. I’m not here to sell you something you don’t need; I’m here to share the lessons we’ve learned supplying TPE tubing to thousands of facilities, because a clean tubing system means a happier client and a better end product.
First, let’s get one thing straight: TPE isn’t a one-size-fits-all material. That’s a big part of why cleaning protocols can’t be generic. At our company, we offer TPE tubing in three core formulations: general-purpose TPE for industrial transfer, medical-grade TPE for biopharma and food contact, and high-temperature TPE for applications like hot water or chemical processing. Each has a slightly different molecular structure, which dictates how it reacts to cleaning agents, temperatures, and scrubbing methods. For example, medical-grade TPE is formulated to comply with USP Class VI standards, so it’s more sensitive to harsh detergents than general-purpose industrial TPE. Skipping this detail is a common mistake I see new clients make, and it’s one that can ruin good tubing.
Before you even pick up a cleaning agent, there are two pre-cleaning steps that are non-negotiable. The first is to drain all residual product or fluid from the tubing immediately after use. Leaving stagnant fluid inside TPE tubing is a fast track to biofilm growth, especially if the tubing is used for aqueous solutions. Biofilm is a sticky layer of microbes that attaches to the inner walls of tubing, and it’s notoriously hard to remove once it sets. If you’re transferring food products like juice or dairy, that biofilm can contaminate entire batches. If you’re in biopharma, it can ruin a lot more than just product—it can lead to regulatory violations. The second pre-clean step is to disassemble the tubing properly. Never force bends or kinks when pulling tubing off fittings; TPE can develop micro-cracks that act as hiding spots for contaminants during cleaning. We always advise our clients to use a tubing cutter designed for TPE, or to pull tubing slowly while applying steady heat (like a hair dryer set to low) if it’s stuck on a rigid fitting. That small step saves you from having to discard damaged tubing prematurely or deal with hidden contamination.
Now, let’s talk about cleaning methods, starting with the safest, most effective approaches that work for nearly all TPE tubing formulations. The first method is cold-water rinsing, which should always be your first step immediately after draining residual product. Use clean, potable water (or deionized water for sensitive applications like lab use) and run it through the tubing at a moderate flow rate—not too fast, which can create turbulence that pushes debris deeper, not too slow, which lets residual fluid sit. For light debris, this is often enough to get the tubing ready for reuse. But if you’re dealing with tougher residues—like dairy fats, industrial oils, or mild chemical residues—you’ll need a mild detergent rinse.
Here’s the science part, and why choosing the right detergent matters for TPE. TPE is resistant to most acids, bases, and common detergents, but harsh, abrasive cleaners can break down its polymer structure over time. What happens then? The tubing becomes porous, letting contaminants seep into the material itself, and it loses its flexibility. For general-purpose TPE, a pH-neutral, non-ionic detergent is ideal. These detergents don’t react with TPE molecules, so they clean the surface without damaging the material. For medical or food-grade TPE, we recommend using a detergent that’s approved for food contact (FDA 21 CFR 176.170) or biopharma cleaning (USP Class VI compatible). Avoid chlorine-based detergents at all costs. Chlorine breaks down TPE’s polymer chains, leading to brittleness and cracking, even after just a few uses. I’ve had clients come to us with tubing that cracked mid-production, and when we tested it, they’d been using bleach to clean it—easy mistake, very costly fix.
If your TPE tubing has heavy residue, or you need to sterilize it (for medical or lab applications), a warm-water soak or gentle ultrasonic cleaning is your next step. Warm water (not hot, we’ll get to that) helps loosen residues without damaging TPE. Soaking time varies by residue: 15 to 30 minutes for light residues, up to 2 hours for heavy ones. Just make sure the water temperature stays below 140°F (60°C). TPE’s melting point can be as low as 160°F (70°C) for some formulations, and even below that, high heat can cause the tubing to soften, warp, or lose its dimensional stability. That’s a key point: always check your tubing’s temperature rating before using warm or hot water for cleaning. Our product team shares temperature guidelines with every client when they order TPE tubing, but it’s easy to misplace that info, so keep it handy.
Ultrasonic cleaning is perfect for small, intricate TPE tubing runs, like those used in lab equipment or diagnostic tools. The ultrasonic waves create tiny bubbles that agitate debris from the inner walls, and because it’s gentle, it doesn’t damage TPE—unlike scrubbing with a brush, which can leave scratches that trap contaminants. Pro tip here: don’t use a metal brush on TPE tubing, even if it feels sturdy. Scratches create crevices where biofilm and bacteria can hide, no matter how well you rinse. A soft nylon brush with non-abrasive cleaners is the way to go if you’re manually scrubbing.
Now, let’s cover what you should never do when cleaning TPE tubing, because these are the mistakes that cause the most damage and downtime. First, never autoclave TPE tubing unless it’s explicitly rated for steam sterilization. Autoclaves use high pressure and high temperature (often 250°F/121°C), which will melt or severely deform most standard TPE tubing. If you need sterile TPE, we offer a medical-grade formulation that’s autoclave-compatible, but even then, we recommend limiting autoclave cycles to 10 or fewer, because repeated high heat will shorten the tubing’s lifespan. Second, never use organic solvents like acetone, alcohol (above 70% concentration), or ketones to clean TPE. These solvents can dissolve or swell TPE, turning flexible tubing into a misshapen mess. I once had a pharmaceutical client who tried using 90% isopropyl alcohol to clean their biopharma TPE tubing, and within a month, half their batch developed leaks—costing them over $50,000 in lost product and regulatory delays. That’s a story I share with every new client to drive home how important material-specific cleaning is.
Third, don’t skip the final rinse step. Even if you used a mild detergent, residual cleaner can leave a film on TPE walls that attracts new contaminants. Rinse twice with clean water, and for sensitive applications, do a final rinse with deionized or distilled water to remove any mineral deposits. Mineral deposits from tap water can build up inside TPE tubing over time, causing blockages and contamination, so this step is non-negotiable for food and medical use.
Once you’ve cleaned your TPE tubing, the drying and storage step is just as important as the cleaning itself. Never let TPE tubing air dry in direct sunlight or near high heat, because UV rays and heat degrade TPE’s polymer structure. Instead, hang it in a cool, dark, well-ventilated space to air dry completely—moisture trapped inside tubing is the #1 cause of mold and biofilm between uses. If you’re drying multiple pieces, don’t let them touch each other while drying, to avoid cross-contamination. Once dry, store the tubing in a clean, closed container, away from chemicals, sharp objects, and direct light. We supply our clients with TPE tubing storage guidelines when they place bulk orders, and we’ve found that facilities that follow these steps extend their tubing’s usable lifespan by 30% on average.
Now, let’s talk about when to replace TPE tubing, even if you’re cleaning it correctly. No matter how gentle you are, TPE tubing has a lifespan, and cleaning can accelerate wear. Look for signs of damage: cracks, brittleness, discoloration, or a change in flexibility. If you notice any of these, replace the tubing immediately. I always tell clients to follow the “clean count” rule: for general-purpose TPE tubing, limit reuse to 5 to 10 cleans, depending on the application. For medical or food-grade TPE, limit it to 2 to 5 cleans, because the material’s purity is critical. Over-reusing tubing may seem like a cost-saver, but it often leads to more expensive downtime or contamination issues down the line.
