Removing Trumpet Vine Tendrils from Stucco

There's no magic product to dissolve trumpet vine holdfasts clinging to stucco. Elbow grease is the main ingredient. Before scrubbing with a stiff brush, soften the tendrils by spraying or brushing on a solution of ¼ cup trisodium phosphate (TSP) per gallon of water. Let it soak, then scrub. It's still work, but the TSP helps release the grip.
