Corsets need proper care to keep in good shape and have long life. The principles are fairly simple, and, if applied consistently, will extend the life and contribute preserving the best looks of any corset. 

Starting with the obvious, it is much easier to put on your corset last, after having put on the rest of your outfit, shoes included.
If needed, see our separate sections on lacing and on shaping (or “breaking”) a corset for more information.
You can consider some absorbing garment under the corset to absorb perspiration and body oils. This will avoid having to clean the corset too often.
Even at it’s nicest-tightest, a corset should not be laced in a way that builds up discomfort. If breathing starts to be problematic, or if cramping appears, it is likely that the corset was laced too tightly and it needs to be loosened up somewhat.
In case it applies to your corset features: always loosen the lacing at the back of the corset before doing up the busk. The same rule applies when taking the corset off. Failure to loosen the laces may result in breaking the busk or boning. Bending over can also cause the busk or bones to permanently be damaged, which may result in durable aesthetic degradation of the corset. Slouching, hunching over, excessive straining movements, etc. while wearing a corset could also cause permanent bending in the busk or boning.
In general, bend with the hips when needed and use your legs, and knees to move up and down.
Eating and drinking is fine, but avoid extra heavy foods, carbohydrates, carbonated beverages and the like: they can cause stomach discomfort. Chewing well is advised.

Regular light cleanliness maintenance is advisable. After normal wear, just keep it open to air out. After a long wearing period, intense dancing or any heavy perspiration wearing period, use a slightly damp cloth and gently wipe the lining of the corset. Let it dry before storing, ideally next to a fan.
NEVER wash a corset yourself, or dip it in water. Most good corsets use steel boning (and some spiral coils that cannot be waterproofed) and washing will cause rust. Buckles and/ or busk may also rust and must be
treated with appropriate care.
Corsets, obviously, need different care depending on the material they are made of. 
Dry cleaning is the only way to wash a fabric corset. When needed (which is not often if the corset is not worn on a daily basis), they should be brought to a trustworthy drycleaner. Since many dry cleaners have no experience of corsets, it is wise to inquire first, and make it clear that boning is made of steel (if it is the case).

One classic way is to fold corsets in half at the lacing, lining side out, and slide a hanger in the middle of the laces for hanging. Another very simple way is to lay it flat in a drawer. The main thing to avoid is to roll the corset: that will very likely damage it.
