Storing and Dusting COBI Military Sets Without Damage

Dust and storage are the two biggest threats to COBI military models. Use soft brushes, compressed air on low, and sealed cases to keep printed parts, tracks, and camouflage intact.
Quick answer
Dust COBI military sets with a soft makeup brush or a camera blower, never a cloth or household duster. Store models in a closed cabinet or a clear case with a silica gel pack. Keep them out of direct sun and away from radiators. These steps protect printed parts, tracks, and camouflage from scratches and fading.
Why COBI military models collect dust differently
COBI military sets have more exposed surfaces than a typical brick build. Tracks, gun barrels, antennas, and open crew compartments create shelves and crevices where dust settles. Printed parts, like the side number on the Tiger tank, are especially vulnerable because abrasive wiping can wear the print over time. Unlike stickers, printed details are part of the brick, but they still need gentle handling to stay sharp.
Tools that remove dust without scratching
A soft makeup brush with synthetic bristles works well for loose dust on flat plates and around small details. For deep crevices, use a camera blower or compressed air held at least six inches away and used in short bursts. Avoid canned air that sprays propellant, and never use a vacuum with a brush attachment directly on the model. For stubborn dust on smooth surfaces, a slightly damp microfiber cloth is safe only on unprinted areas, but wring it out thoroughly first.
Step-by-step dusting routine for a built set
Start at the top and work downward so dust does not fall onto already-cleaned sections. Use the soft brush to sweep dust off large plates and the blower for tracks and turret rings. If your model has movable parts, like the Hummel's gun, avoid forcing them while dusting. Once a month is enough for most displays. In a workshop or near an open window, dust weekly.
Storage options that protect without hiding the model
Clear acrylic cases or glass cabinets keep dust off while letting you see the model. If you use open shelving, place models at least two inches from the wall and add a thin strip of foam weatherstripping to shelf edges to reduce dust migration. For long-term storage, remove delicate parts like antennas and store them in a labeled zip bag. Avoid cardboard boxes; they shed fibers and can attract pests. Add a silica gel packet to closed containers to control humidity, which can loosen printed details over time.
When to stop and choose another approach
If your model is already showing scratched or faded printed parts, further dusting will not fix the damage. In that case, consider a replacement set or move the model to a less prominent display spot. If you live in a very humid climate and see white haze on bricks, stop dusting and focus on dehumidification first. For models with fragile aftermarket parts, a sealed case is the only safe option. If you cannot commit to a dusting routine every few weeks, choose a closed display case from the start.
Diagnosis: common dust and storage problems
- Dust settles in tracks and turret rings: Dust builds up in the gaps between track links and around rotating turrets. Use a camera blower or compressed air on low, holding the nozzle at least six inches away. Do not use a brush that can push dust deeper. If dust remains after two passes, stop; further force may dislodge parts.
- Printed parts look dull or scratched: Printed details like the Tiger's side number can wear if wiped with a cloth. Switch to a soft makeup brush and use only light strokes. Never use water or cleaning sprays on printed areas. If the print is already faded, no cleaning method will restore it; consider a replacement set or display the model as-is.
- Model feels sticky or shows white haze: Humidity can cause a sticky residue or white haze on bricks. Move the model to a drier spot and add silica gel packs to the display area. Do not try to wash the model; moisture can damage printed parts and internal connections. If haze persists after a week in a dry environment, the damage may be permanent; consult COBI customer support before attempting repairs.
Product facts
- COBI Boeing F-15EX Eagle II Fighter Jet : Set #5900: COBI Boeing F-15EX Eagle II Fighter Jet : Set #5900 is a 1:48 scale model of a modern heavy fighter. Its scale and open landing gear create many small surfaces that collect dust, so a soft brush and low-pressure air are safer than a cloth.
- COBI Panzerhaubitze "Hummel" Sd.Kfz.165 Self-Propelled Gun : Set #2663: COBI Panzerhaubitze "Hummel" Sd.Kfz.165 Self-Propelled Gun : Set #2663 is a large-scale 1:28 self-propelled gun model. The larger scale means bigger flat panels that show dust quickly, but also more crevices around the gun and tracks where dust hides.
- COBI Pz.Kpfw. VI Tiger Ausf. E Tank : Set #3124: COBI Pz.Kpfw. VI Tiger Ausf. E Tank : Set #3124 features a printed side number 114, modeled after a museum exhibit. Printed numbers and markings can wear off with abrasive cleaning, so use a soft brush only and avoid damp cloths on printed areas.
