Now you have your wardrobe installed and in use it is easy to maintain and keep looking as good as the day it was installed. All coloured glass and mirror doors can be cleaned with any proprietary glass cleaner. Cleaning products with an anti-static additive may reduce the period between cleaning.
If you have frosted (acid etched) glass this should be cleaned with clean warm water only and the whole surface should be cleaned rather than just a local area as this glass can mark if not cleaned in this way.
To keep your sliding doors running smoothly make sure they are kept dust free by vacuuming the tracks regularly. Care should be taken not to get anything stuck in the tracks....wire hangers in particular can damage the bottom wheels, and in some circumstances can lead to de-railment. The metal door frames and tracks should be cleaned with a dry or damp cloth only and any wood effect panels should be cleaned in this way too.
