The Matrix Lace Cleaner by Max Adhesives is the best lace cleaner in the market today. Used by technicians in the back room to clean the stubborn adhesive build-up from the lace bases (as well as lace fronts).
The most effective way to use is to pour into a large tupperware container and allow the unit (or the lace front only) to soak in the cleaner for a few minutes. Then, remove the unit, rinse thoroughly, shampoo/condition and the adhesive will be gone.
32 oz bottle.
