Getting Rid of Black Mold Around Shower

Use a 50/50 bleach/water solution in a bucket. Use hot but not scalding water. Take a stiff bristled handheld bathtub brush and alternate between dipping the brush in the bucket and scrubbing at the mold until it is all gone. The bleach should remove the stain left by the mold. If not you can try some concentrated bleach on a white rag, wearing gloves. Be careful not to damage the caulk. If the caulk is leaking in any way, remove, clean and re-caulk. Rinse clean with water and you should be good to go.
