How to get rid of mold on Garden Hose?

Try white vinegar, or put on some rubber gloves and attack it with Lysol.

Cleaning it is only a temporary fix. It's going to keep coming back until you take care of the cause. Find the leak, and fix it. Unroll the hose, and let it sit in the air and the sunlight to let the anaerobic mold die. Then wipe it off with a rag dampened with detergent, and let it dry completely before rolling it up again. If you fixed the moisture problem, the mold won't come back. If you didn't fix the moisture problem, it really doesn't matter what you clean it with because the mold will come back.

Try deck cleaner. Worked on a lawn chair with mold on the plastic.

Tilex ought to work pretty well, but as Warren said, you need to cure the problem, not the symptom.

As long as the garden hose remains outdoors in a damp climate on the ground, placed on supports above the ground, or rolled on a holder it will be attacked by black mold whether in Pennsylvania or North Carolina or in between. Bright yellow and green hose, red hose, clear hose. Using a tub, I soaked my hose, fully submerged, in up to 3 X the recommended solution of Clorox, Lysol, Ferti-lome Liquid Systemic Fungicide II, and Moldstat 2. and a combination of all four. The hose laughs at me. I took the hose to the sand pit and soaked them all in gasoline and lit, ball of fire. No more laughing, no more mold, no more hose. I just replaced with black hose. I can't see the mold now. This is not a joke.
