What is the proper way to eliminate small patches of mold? Bleach only seems to work a short while.

No contractors please. This is not a large job.

If you are using 50% water-bleach mixture and it comes back, then the problem is persistent high moisture content - either from water leaking (dripping pipe, seeping through basement wall, etc), or from too humid an environmetn (over 60%) such as an unventilated unheated basement or a bathroom where the fan is not run during and for about 30 minutes after each bath or shower.

Get rid of the moisture source and the mold will not come back.

In addition to the bleach treatment to kill current mold, you might also try adding Borax (pure Borax, NOT Boraxo soap) to the scrubbing solution - is slightly abrasive like baking soda so cleans better, plus suppresses mold growth.

If you paint over the area after removing the mold, use Kilz as a primer, then in the finish coat add a mildewcide - comes as a powder and can be mixed into almost any paint - check instructions for whether your brand can be used with pure white or not - may discolor pure white a bit.
