You should use 90% alcohol. Simply coat a Q-tip with alcohol and run it along the strip of the lashes, the magnets, and the lashes themselves. This will ensure your Je Suis Diva magnetic lashes are completely free of any makeup or eyeliner residue and ready for the next use. If you need to reshape your lashes, it’s best to do so when they are still damp. We suggest storing your dry lashes in the original box to maintain their shape.
