After repeated use, dry white glue crusts accumulate on plastic lash trays, sticking lash bands permanently and breeding bacteria under leftover adhesive. Dirty trays contaminate clean lashes every time you store strips, triggering eye irritation during next wear. Mild cleaning solution formula: mix warm water + tiny drop of non-oil facial cleanser, stir evenly. Dip a soft cotton pad in the mixture and press onto glue crusts on the tray for 30 seconds to soften hard adhesive. Gently scrape residue with a plastic toothpick (avoid metal tools that scratch plastic tray surface). Do not use acetone, alcohol or oil remover to clean lash trays—strong solvents fog transparent plastic and leave oily film that ruins lash band adhesion later. After scraping all glue off, wipe tray with clean damp tissue and air-dry fully before placing lashes back. Sanitize lash trays once every two weeks for hygienic use: wipe inner surfaces with alcohol-free antibacterial makeup wipe to kill invisible bacteria from eye skin contact. Store lash boxes open to ventilate after cleaning to prevent mold growth in damp bathroom cabinets.
