Multipurpose solution
Cleans, rinses, disinfects and stores. Convenient, but needs rubbing for most formulations to work properly. Never reuse it; discard after the stated period once opened.
Hydrogen peroxide systems
Disinfect more thoroughly than multipurpose solutions because they are preservative-free. They require the matching case and a neutralisation time of about six hours, and must never be used as a rinse.
Saline
Rinses only. It does not disinfect and is not a storage solution. Using saline as the only solution is a common cause of infection.
Rewetting drops
For comfort during the day, not for storage. Choose preservative-free for frequent use.
Two mistakes
Topping up old solution instead of replacing it, and using tap water at any point. Both turn the case into a source of organisms.
