No, I was thinking of reaching in there and pulling clumps of it off the rock... scrubbing would result in pieces floating all over the tank and taking root elsewhere.
(But in my personal experience, I've had snails and/or fish that would then clean up the remainder... as long as i kept it from growing faster than they clean/eat.)
If you want to scrub every last bit, then remove the rock from the tank... clean and scrub all you want, then rinse it in clean water and put it back in the tank... That method would certainly get rid of more of the algae than just clearing it as it grows.
