How to Clean a Garden Hose? | The Right Way, Step by Step

A thorough clean with mild soap and water, plus a vinegar soak for the interior, keeps a garden hose flowing freely and free of mold and mildew.

For the full breakdown, see our best Garden Hose Cleaner guide.

The inside can grow a slimy biofilm, the outside gets caked with dirt and algae, and the fittings clog with grit.

What You Need to Clean a Garden Hose

The materials are basic household items you almost certainly already have. Gather a bucket, mild dish soap, white vinegar, a soft brush or sponge, an old toothbrush, and a clean cloth. A pair of gloves is handy if you opt for a stronger vinegar solution.

The Basic Cleaning Workflow

Disconnect the hose from both the spigot and the nozzle, drain every drop of water, then flush it by running clean water through the full length before you start scrubbing. That first flush pushes out loose debris and tells you how dirty the inside really is.

Exterior Cleaning

Mix a small squirt of mild dish soap into a bucket of warm water. Dip your soft brush or sponge and scrub the hose’s full length, paying extra attention to any green algae spots or muddy sections. Rinse with clean water from the spigot until the water runs clear.

Fittings and Nozzles

Soak the fittings and nozzle in the same soapy water for a few minutes. Use the toothbrush to scrub the threads and any recessed areas where grit collects. Rinse them thoroughly and set them aside to air dry.

Deep Cleaning the Interior

Over time, the inside of a hose can develop a stubborn film that smells musty and can harbor bacteria. This is the step that removes it. Fill the hose with a solution of 1 part white vinegar to 3 parts water, cap or kink the ends so the liquid stays in, and let it soak for about 30 minutes. One source recommends a 1:1 vinegar-to-water ratio for heavier buildup — either works, but the stronger mix may produce a stronger vinegar smell during the flush. After soaking, flush the hose thoroughly with clean water until the vinegar odor is gone. If soap residue is a concern — and it should be if you water plants with this hose — follow the vinegar flush with a plain-water flush until no bubbles or suds appear.

Drying and Storage

Hang the hose in a shaded spot or lay it out flat on a clean, dry surface. Leave it until the inside is bone dry — you should feel no moisture when you touch the connector opening. Then coil it loosely and store it in a dry, shaded area. Sunlight degrades the rubber or vinyl over time, so a garage or shed is ideal.

While the hose is dry, inspect it for cracks, soft spots, flat sections, or rusted fittings.
