If there is any dried magnetic liner stuck onto the magnets, use your thumb nail to scratch off as much as possible. Use a makeup wipe to gently clean off any remnants on each of the magnets (We love Neutrogena makeup remover wipes!). Use the wipe to clean off the magnetic strip in the box as well, then magnetize the lashes back into the box! Please DO NOT get the lashes wet as this could ruin their curl and shape!
