Cleaning Plastic Cages & Overlays
Clear plastic cages on Air Max 95s and 97s, hardware overlays on Jordans — these don't get dirty so much as damaged or yellowed by UV. Care is mostly prevention: store them away from direct sun, clean gently, and accept that some yellowing is part of the journey.
Overview
How often
Wipe overlays whenever you clean the rest of the pair, roughly every 30 wears. Treat yellowing when you see it, and reproof waterproof membranes every 12–18 months.
Materials covered
TPU (overlays / cages), Waterproof membrane, Rubberized upper / mudguard, Printed / embossed panel, RPU exoskeleton cage, PVC / jelly

Picked for the material, not paid for. Test anything new on a hidden spot first.
Step by step
Step 1: Wipe with damp microfiber
Plain water for daily dust. Mild soap dilution for stuck dirt.
Step 2: Scuffs on rubber mudguards
Magic Eraser, very light pressure. Test in a hidden spot first. Not on printed or embossed panels: it takes the print off.

Apply Angelus Sole Bright or Reshoevn8r Sole Revive in a thin coat and wrap with cling film. Cure under a UVA nail or resin curing lamp (never a UV-C germicidal lamp), or in mild sun while checking that the surface never gets hot to the touch — heat softens TPU. Re-apply every few hours. Mask off adjacent suede or fabric — these products bleach. Gloves and eye protection, a ventilated room, and don't sit under the lamp.
Skip for PVC / jellyStep 4: Reflective prints
Wipe only. Never brush, never use solvent cleaners. The reflective layer is metallic foil under a thin protective coat; abrasion strips it permanently.
Skip for PVC / jellyStep 5: Elephant print
Wipe only. The print is on top of the leather/synthetic substrate; the pattern wears off, it doesn't wash out.
Skip for PVC / jellyStep 6: Gore-Tex / waterproof membranes
Clean the outer fabric gently, for example with Nikwax Footwear Cleaning Gel — the membrane sits inside the shoe. No heat ever (the membrane delaminates). Re-treat with Nikwax Fabric & Leather Proof when water stops beading, usually every 12-18 months.
Skip for PVC / jellyStep 7: Jelly and PVC: wash
PVC is one of the few uppers that can be washed: mild soap and lukewarm water, a soft cloth or brush, rinse, and dry out of the sun. Never hot water, solvents or a dryer: PVC warps and yellows.
Only for PVC / jelly
What to avoid
- Brushes or solvents on reflective or printed panels
- Any heat on waterproof membranes
- Sole brightener near suede, fabric or printed graphics
- Displaying pairs in direct sunlight
Watch for
- Tpu ambering. Move the pair into dark storage. Sole brightener can lighten it but rarely returns TPU fully to clear; prevention works better.
- Elephant print cracking. Can't be reversed. Shoe trees between wears slow it down.
By material
The routine above, adjusted for each material it covers.
TPU (overlays / cages)
Clear TPU yellows the most under UV. Pigmented (colored) TPU is far more stable. Sole brightener works best on clear TPU; cracked pigmented TPU can't be restored.
Waterproof membrane
Reproof with Nikwax Fabric & Leather Proof every 12-18 months. Never tumble dry or use heat. No fabric softener.
Rubberized upper / mudguard
Most forgiving in this archetype. Magic Eraser-friendly. Yellowing is rare on opaque pigmented rubber.
Printed / embossed panel
Wipe-only, always — the print layer is thin. Protector spray helps printed graphics last. Elephant print cracking is flex damage at the toe box; shoe trees reduce it. Reflective 3M print loses its reflectivity with years of UV. Glow-in-the-dark print charges with UV but fades with long exposure — brief charging is fine, display in sunlight is not.
RPU exoskeleton cage
Rigid PU — treat it like a Foamposite shell (see Cleaning Foamposites). It can break down over years of storage, so keep it cool, dry and dark.
PVC / jelly
Jelly shoes and PVC: wash with mild soap and water, dry out of the sun. Clear PVC yellows with UV and stiffens and cracks in the cold. No sole brightener.
Between wears
- Uv protection. Dark, cool, dry. UV is the #1 enemy. A closet shelf away from windows is fine. A display case with glass front is bad if it's in sunlight.
- Display. If you display pairs, keep the case out of direct sunlight. A closed box beats a glass-front case near a window.
- Humidity. Silica gel packets in the box for humid climates (Houston, Miami, etc.).
- Pressure. Don't store stacked under heavy items — TPU flex zones can deform under prolonged compression.

Cleaning Stretch Sock Uppers
Soft, porous foam-family uppers — Sock Darts, ACG booties, some training silhouettes. They don't tolerate aggressive cleaning. Stick to a damp cloth, mild soap, and air drying. Avoid solvents and direct heat.

Cleaning Foamposites
The Foamposite upper is a one-piece molded polyurethane shell — completely sealed and surprisingly easy to clean. A damp microfiber wipes off most marks. The risk areas are deep scuffs (almost impossible to repair) and the inner foam degrading over years of storage.
