Keeping your RV shower pristine is a simple task, especially given its compact size! With a few basic household cleaning supplies and a touch of effort, you'll have your RV's shower sparkling clean in no time. Remember to avoid harsh chemicals to prevent them from entering your grey wastewater tank.
Steps
Floor and Walls

Create a gentle yet effective cleaning solution by mixing dish soap, vinegar, and water. Blend approximately 1 US tbsp (15 mL) of liquid dish detergent, 2 cups (473 mL) of water, and 1 cup (237 mL) of white vinegar in a clean spray bottle. Secure the lid and shake the bottle several times to thoroughly mix the ingredients.
- This cleaning solution is ideal for removing soap scum, hard water spots, and general grime.

Use a bleach and water mixture in a spray bottle to eliminate mold and mildew. Mix 1 cup (237 mL) of bleach with 1 gallon (3.79 L) of water in a spray bottle and shake well to blend the solution. Apply this solution to your RV shower following the same steps as you would with an all-purpose cleaner.
- This solution effectively removes and kills mold and mildew, which may manifest as dark brown, green, or black spots on various surfaces in your RV shower.

Spritz the cleaning solution onto your RV shower's floor and walls. Direct the spray bottle nozzle into the shower and squeeze the trigger while moving it back and forth over the surfaces until everything is evenly coated with the cleaner.
- If preferred, work on one wall at a time before tackling the floor.
- For stubborn stains, allow the all-purpose cleaner to sit for a few minutes. To address mold and mildew, let the bleach solution sit for up to 24 hours to ensure complete spore eradication.

Scrub the surfaces with a damp sponge to remove the cleaner. Wet the sponge under running water or dip it into a bucket of clean water. Start from the top and work your way down, wiping each wall and then the shower floor.
- Rinse the sponge frequently as you work to remove any dirt buildup.
- For areas affected by mold and mildew, concentrate your scrubbing efforts accordingly.
- To tackle hard-to-reach spots, use a cotton swab to remove stains or mold and mildew.

Rinse the shower thoroughly using the shower head. Turn on the shower head and spray down the walls and floor to wash away any leftover cleaning solution.
- If your shower head lacks a hose, you can use a garden hose or buckets of fresh water to rinse the shower.

Allow your RV shower to air dry by leaving it open. Increase ventilation by opening the shower door and any bathroom windows. If you prefer a faster drying process, use an old towel to wipe down the walls and floor.
- For quicker drying, wipe down the walls and floor with an old towel.
Shower Head and Fixtures

Detach the shower head from the hose or shower pipe. Hold the base of the shower head with one hand and the hose or pipe with the other. Twist the shower head counterclockwise until it loosens and can be removed.
- If there's a nut at the base, loosen it before pulling off the head.

Flush white vinegar through the shower head to cleanse the interior. Position the shower head vertically over a sink or container. Slowly pour white vinegar into the opening at the base of the shower head, where it connects to the hose or pipe.
- Vinegar helps dissolve mineral deposits from hard water inside the shower head.

Immerse the shower head in white vinegar to clear the spray holes. Submerge the spray end of the shower head in a small bowl or container filled with white vinegar. Ensure all spray holes are completely covered.
- For stubbornly clogged holes, use a toothpick or similar tool to dislodge mineral deposits.

Cleanse the shower head and other fixtures with gentle dish soap and water. Apply a few drops of dish soap to a damp sponge or cloth. Scrub the exterior of the shower head, hose or pipe, and other fixtures within the shower.
- If mineral deposits are present, use a mixture of 2 parts water to 1 part vinegar.
- Alternatively, use disinfecting wipes for a quick clean.
Shower Drain

Use baking soda and vinegar to unclog and cleanse the drain. Pour approximately 3 tbsp (60 g) of baking soda down the drain, followed by about 1 cup (237 mL) of white vinegar. Allow the mixture to sit for several hours or overnight to loosen any buildup.
- If your shower drain is slow, try this method to clear blockages and enhance drainage.
- Avoid harsh chemical drain cleaners like Drano, as they can harm your wastewater tank.

Flush the drain with hot water to remove debris. Turn on the hot water and direct it down the drain. Hold the stream of water over the drain for a minute or two to wash away the baking soda, vinegar, and loosened debris.
- If the drain remains sluggish, repeat the baking soda and vinegar treatment until the issue improves.

Remove hair and debris from the drain using a wire coat hanger. Straighten out a wire coat hanger and insert it into the drain to extract any trapped materials. Alternatively, use needle-nose pliers or a similar tool for this task.
- Consider placing a shower drain screen to catch hair and debris and prevent clogs.

Brighten discolored drain surfaces with baking soda. Sprinkle baking soda onto stained areas around the drain and scrub with a wet dish scrubbing pad or toothbrush. This method is effective for removing stains, especially from white plastic shower drains.
- To access hard-to-reach areas inside the drain, attach an old toothbrush to a long metal rod using duct tape.
Helpful Tips
-
Always keep dish soap, white vinegar, and baking powder in your RV for easy access when it's time to deep clean your shower.
-
If your RV shower drain lacks a drain screen, consider installing one to prevent hair and debris from clogging the drain.
