I assume you have lace-release? Just spray that through the lace onto the glue .....allow plenty time to penetrate/work [at least 2/3 mins] That should leave most of the glue residue on your scalp rather than on the lace. You could try Surgical spirit [alcohol ]from a pharmacy but keep it off the hair if at all possible ... sounds like you already have alcohol anyway ..... hopefully there won`t be a lot on the lace.......you don`t have to get it like, squeaky -clean as such....hopefully your citrus product will arrive soon.....regards, Paul.
