What success looks like
Pile-body cleaning succeeds when units are readable and users feel the service is tended, not when a crew simply wiped once. A visible standard, like a dated check, makes the effect observable, because a clean pile that hides a cracked cover is cosmetics, not care, and users can tell the difference.
How to judge it
Dongshang New Energy checks user perception and tracks faults caused by hidden damage or grime. If complaints about unclear status drop, the cleaning routine is working; if not, the method needs change, since the only meaningful test of cleaning is whether the user's experience actually improved, not whether a cloth was used.
Keep improving
Treat cleaning as a measured task, not a chore. The payoff is fewer support calls and a site that signals care, which is exactly the quiet experience users remember and reward, and a program reviewed by outcome learns faster than one judged by the effort someone put in.
