I bought the leather care mainly for my car set. Can also be used in the household. To maintain the leather, the agent is really great. The car smells very discreetly after treatment with Liqui Moly for new cars. Not really pushy, but you take a pleasant smell true. Soon after dosing, the leather looks a bit tacky, but this will disappear after a short exposure.
For already "threadbare" provide the means but does not help. It is merely to prevent that the leather remains supple / is.
