The Magic Lappen must first be made completely wet with clean water (cold or warm). Then it must be wrung out very vigorously so that it feels almost dry. Thus damp, the Magic Lappen is ready for use and leaves no streaks on smooth and shiny surfaces. After use, rinse the Magic Lappen with clear, preferably hot water; if necessary, wash in the washing machine up to 60° and store well dried.
Important note: avoid fabric softener at all costs, tumble dryer and iron, otherwise the structure will be changed and the fantastic function is thereby no longer given.
