There isn't written much about scrubbing in this forum, so i decided to share this handy technique with all of you. You can take your time when picking a lock at home just to have fun but in cases when you have lost your front door key in a rainy evening and you need to get into your home as quickly as possible, so scrubbing can help you in picking your front door lock in minimum amount of time.
So here is a detailed method :
1. Insert the pick and torque wrench. Without applying any torque pull the pick out to get a feel for the stiffness of the lock's springs.
2. Apply a light torque. Insert the pick without touching the pins. As you pull the pick out, apply pressure to the pins. The pressure should be slightly larger than the minimum necessary to overcome the spring force.
3. Gradually increase the torque with each stroke of the pick until pins begin to set.
4. Keeping the torque fixed, scrub back and forth over the pins that have not set. If additional pins do not set, release the torque and start over with the torque found in the last step.
5. Once the majority of the pins have been set, increase the torque and scrub the pins with a slightly larger pressure. This will set any pins which have set low due to beveled edges, etc.
Scrubbing is fast because you don't need to pay attention to individual pins. You only need to find the correct torque and pressure
