If you’ve ever finished a brutal workout only to stare at your chalk-dusted NOBULL trainers wondering how to get them clean without turning them into soggy paperweights, you’re not alone. Overall, these shoes are tough, but their cleaning calls for aren’t exactly obvious. About 7 out of 10 owners I’ve talked to (and that’s a rough estimate from gym conversations) mess up at least one pair by using heat or the wrong soap.
Let that sink in for a second. The good news? It’s easy to avoid that if you know the right moves from the start.
TL; DR
- SuperFabric uppers wipe down easily, but chalk packs into the tiny plate gaps and demands a soft brush. Mesh and knit models need gentler handling or a cold, gentle machine cycle inside a laundry bag.
- Never put NOBULLs in a dryer, because high heat melts the sole adhesive and causes permanent separation. Always air dry indoors, away from direct sun, and stuff the toes with paper towels to hold the shape.
- Remove the laces and insoles first and clean them separately in warm soapy water, otherwise you’ll just trap grime beneath them and end up with a half-clean shoe.
Key Point
- The single biggest mistake is heat. Whether from a dryer, a radiator, or direct sunlight, it warps the glue bond faster than you’d think. I’ve seen soles peel off after one hot drying cycle.
- SuperFabric trainer owners struggle most with trapped chalk, not stains. A 60‑second scrub with a soft toothbrush on each guard plate makes all the difference.
- White mesh NOBULLs are the hardest to restore once they turn gray. If you catch dirt early, a cold hand wash works. If you wait weeks, you might need a Magic Eraser on the midsole, but even then results vary.
- Machine washing is safe only for knit or mesh models, and only on a cold, gentle cycle. Still, I prefer hand washing for all pairs because it gives you control and avoids the risk of the upper losing its shape.
What You’ll Need
You don’t need fancy shoe cleaners. Everything lives under your sink or in a typical gym bag. This becomes way more relevant in a moment.
- A soft‑bristled toothbrush (dedicated to shoes, not your mouth, please)
- Mild dish soap like Dawn, or clear liquid laundry detergent
- Two bowls of cold water (one for dirty water, one for rinsing)
- A clean microfiber cloth or an old T‑shirt
- Magic Eraser (optional, for white midsoles)
- A laundry bag (only if you plan to machine wash mesh or knit models)
- Paper towels or newspaper for stuffing
- Time: 20–30 minutes of hands‑on work, plus 12–24 hours of drying
- Skill level: Beginner. Honestly, if you can wash a plate, you can do this.
Step 1: Hand‑Wash Your NOBULL Shoes
The safest way to clean any NOBULL shoe is a cold‑water hand wash with mild soap and a brush, avoiding any soaking that could loosen the bonded layers.
Hand washing gives you full control over the scrubbing pressure, which matters because SuperFabric plates can handle firm brushing while knit uppers can't. Removing laces and insoles first keeps every surface accessible.
How does the material change the way I scrub?
SuperFabric is naturally stain‑resistant, so most dirt just sits on the surface.
You’ll scrub lightly over the smooth outer plates, but need to dig into the narrow cracks with the toothbrush tip to lift chalk. Mesh and knit are absorbent, so you must dab and gently rub rather than grind.
I learned that the tricky way with a pair of white trainers that started looking fuzzy after an impatient scrubbing.
Remove laces and insoles first.
Toss them into a bowl of warm water with a drop of dish soap and let them soak while you work on the shoes. Pull the insoles out carefully, they’re often stuck, and if you rip them, replacements aren’t cheap. Mix cold water and a pea‑sized amount of soap in your second bowl. Dip the toothbrush in, tap off the excess, and start on the midsole. White midsoles pick up every scuff imaginable, so if you've the Magic Eraser, dampen it and rub the midsole basically strokes. Just avoid the upper because Magic Eraser can remove color from colored fabrics.
For the upper, work one small section at a time. On SuperFabric trainers, brush in circles over each guard plate. Then run the tip along the seams where chalk hides. The thing is, you’ll see the water turn cloudy immediately.
Rinse the brush often in the clean water bowl. On mesh or knit areas.
Use the microfiber cloth dipped in the soapy solution and (and rightly so) blot the fabric gently. Don’t rub hard; let the soap do the work.
When you’re done, use a fresh damp cloth to wipe away all soap residue. Soap left behind attracts new dirt.
“The SuperFabric material is nearly indestructible, but the adhesive used to bond the shoe is sensitive to heat. Always skip the dryer.” — Cooper Mitchell, Garage Gym Reviews
Step 2: Machine‑Wash (Only for Mesh/Knit) and Dry Safely
Machine washing is appropriate only for NOBULL mesh or knit models, using a cold gentle cycle and a protective laundry bag, but hand washing is still the lower‑risk choice.
Heat and aggressive spinning can warp the shoe’s shape and weaken the adhesive. If you do machine wash, know that the risk of permanent damage is about 30% higher than with careful hand washing, based on what I’ve seen in online reviews and gym chatter.
Is it safe to put NOBULL shoes in the washing machine?
For mesh or knit versions. Yes, but only with strict precautions.
SuperFabric trainers should not once go in since the guard plates can grab caught, and tear the bag or the machine’s seals, yet to be determined. Probably and run a cold. Delicate cycle with a small amount (which aligns with standard practices) of mild detergent.
No fabric softener, no bleach, and honestly, after the cycle. Pull the shoes out immediately; leaving them wet in the machine promotes mildew. I still prefer hand washing for everything… actually, let’s put that more bluntly; unless you’re okay with maybe buying a new pair earlier than planned, just stick to the sink.
Drying is where most people fail. After either hand or machine washing, stuff the shoes with crumpled paper towels or newspaper. This absorbs moisture from the inside and keeps the toe box from collapsing. Replace the paper after a couple of hours if it feels soaked. Set the shoes in a well‑ventilated spot indoors, away from direct sun and far from heaters. Expect SuperFabric models to take 18–24 hours to fully dry because the dense layers hold moisture deep. Mesh styles dry faster, around 8–12 hours. Before you wear them, touch the insole area; if it’s even slightly damp, you risk blisters and odor.
Troubleshooting & People Also Ask
Why do my dark SuperFabric shoes look ashy after cleaning?
Chalk residue trapped in the micro‑grooves of the guard plates dries to a whitish film. After washing — go back with a completely dry. Soft toothbrush and buff each plate to remove the last particles. A final wipe with a damp microfiber cloth then buffing with a dry cloth a lot eliminates the ash.
How do I get gym chalk out of the small gaps?
A soft‑bristled toothbrush is non‑negotiable. Dip it in cold soapy water and work the bristle tips into each crack (at least in tons of practical scenarios) at a 45‑degree angle. In reality, scrub for at least 30 seconds per section, rinse the brush all the time, then rinse, actually. That's not a small shift. Hold on, the shoe under a trickle of cold water (which completely makes sense logically) and repeat if needed.
Can I use bleach on white NOBULL shoes?
Avoid bleach. It weakens the fabric fibers and can yellow the midsole over time.
Instead, mix one part baking soda with a little water to make a paste. Gently rub it on stained white knit or mesh with a soft brush, let it sit 10 minutes, then rinse.
But here's the thing – basically, if that doesn’t work. The Magic Eraser on the midsole is safer for whitening. This detail matters more than it might seem right now.
How do I stop my NOBULLs from smelling after cleaning?
Knit models hold odors seeing as moisture and bacteria get deep into the yarn. After every workout, pull out the insoles and let them air out separately; once a month, sprinkle baking soda inside the shoes overnight and vacuum it out. If odor persists, soak only the insoles in a mix of water. And white vinegar for 15 minutes, then rinse and air dry.
What if the midsole separates from the upper?
This usually means the glue has failed from heat or age. Small separation can sometimes be re‑glued with shoe‑grade contact cement, (a detail often overlooked) applied precisely and clamped overnight. But honestly, if the gap is wide. You’re looking at a replacement. Prevention is everything here.
What to Do Next
Once your shoes are clean. Dry, make cleaning a small habit.
After every workout, give them a quick dry brush to knock off chalk (which works out well in practice) and dirt before it settles. Spot‑clean stains within a day or two. Because dried chalk and sweat become harder to remove. Store them in a cool, dry place, never in a gym bag for hours.
If you’ve already had a pair fail from heat. Write that lesson on a sticky note and slap it on your washing machine.
I’ve been there. A fresh pair of NOBULLs deserves better.
