sticky extensions?? help

hey everyone, i have been doing great lengths extenions and have used yhs for about 4 years now...and experimented with a couple other lines but my friend got some "free" bonded extensions done and i tried removing a bond with just the pliers and it took awhile. then i tried alittle of the great lengths remover and it came out quick but left a little bit of bond and it was really sticky...she doesnt and wont be able to find out what kinda hair or bond it was so how do i get rid of the stickyness of the leftover bond without her ruining her hair?!?!

Citre Shine shampoo and a comb?
