Never clean without locking the moving parts
In the TBC world, not everything that seems still really is.
Doors, hatches, blades, mechanical arms, adjustable antennas, wheels, levers, opening panels, and small articulated elements can move even with simple contact. During cleaning, just a light pressure or the passing of a tool is enough to make them swing, collide with other parts, or detach.
Cleaning without first identifying and stabilizing the moving parts is a mistake to avoid.
An item that moves suddenly can get scratched, bend, lose alignment, or damage nearby details. In some cases, the issue doesn't just affect a single piece: a small movement can trigger a chain reaction and compromise the entire construction.
A true TBC operator observes before intervening.
Check which parts can move, secures them gently, and chooses the correct point from which to start.
Only afterwards move on to cleaning.
The principle is simple: what can move must first be controlled.
Accuracy comes before speed and safety before action.
TBC Rule: First it is made safe, then it is cleaned.
