Hi, I use about 10-15 drops of the super cleaner...use a carbon fiber brush to spread around...vacumn 2 rev's.
Then I partially saturate a disc doctor brush with the wash, go around once using the motor. scrub back and forth (with the grooves) once or twice. Vacumn 2 rev's.
Works like a champ for me.
To answer your question...using the vpi brush..not hard...it's job is to spread the fluid only. Let the fluid to the work. I'd say 2 rev's...one will likely do it...but 2 won't hurt. I'd use as much fluid as you can as long as it doesn't spill off the sides much. Also, 2 vacumn tubes seems to help...one for the deep cleaner...one for the super wash.
