The efficient technician lightens their tool bag as much as possible. Reduce liquids from large containers to small containers that hold just enough for a week of service. Schedule an hour at The Container Store to find the right container for the different types of liquid you frequently reach for during your house calls.

Make sure to do a tool bag clean out at the end of the week and top off the liquids you used in your small containers.
