Lace release is not a solvent as such.. it has alcohol in it to break the bond...you need the stronger solvents to help dissolve/remove the residue... you should be able to buy surgical-spirit [basically alcohol] at a pharmacy.. I bought a 500ml bottle for the equivalent of 5£ here. It`s not ideal, but better than nothing... bubble wrap can help to remove residue from the lace... the solvents are more aimed at cleaning residue from your scalp... I suppose you could try lemon juice and see what way it works...never tried it myself.
