RV Plumbing Tips – Cleaning RV Faucets, Sink Drains & Shower Wands

The effects of hard water on RV sinks, faucets and drains can be an ongoing problem for RVers. This page describes a few tips for how we remove these pesky mineral deposit buildups from our bathroom and kitchen sinks in our fifth wheel trailer and keep the water flowing smoothly in our shower wand and RV toilet rinse sprayer.

RV plumbing tips for removing mineral deposits and cleaning RV faucets and drains.

We like the water to flow freely in our RV vanity sink faucet, kitchen sink faucet and in the shower and RV toilet sprayer wands, however, periodically these faucets begin to spray water in weird directions because their inner workings have gotten clogged up by mineral deposits from the hard water.

In our bathroom vanity, our first step is to remove and clean the screen filter in the faucet. Sometimes the faucet tip can be unscrewed by hand, but if we’ve let it go too long, we have to use a pair of pliers to break the faucet tip free due to corrosion that makes it impossible to unscrew.

Then we unscrew the entire screen assembly from the faucet.

Ugh… the screen is pretty dirty. No wonder the water comes out funny!

This time the screen was very corroded. We remove the corrosion and mineral buildup by putting all the pieces in a bath of white vinegar for 20-30 minutes or so.

Prior to putting the pieces in the white vinegar bath, it is a good idea to make note of the order that these parts go into the faucet assembly!

Soak RV faucet parts in white vinegar

After noting how the pieces go together, soak them in white vinegar.

After the bath, the bits of corrosion can be seen in the white vinegar!

Here are all the pieces. You can see the dirt that came off in the vinegar bath!

Using an old toothbrush, we scrub each piece until it is clean.

Then we reassemble the pieces in the correct order and orientation.

To make it easier to remove the faucet tip the next time we do this job, it helps to grease the threads with a marine PTEF lubricant prior to screwing the assembly back onto the faucet.

Ta da! Now the flow will be smooth and full.

Our trailer has white plastic sinks in the bathroom and kitchen, and these sinks often develop a skanky brown ring around the sink drain. For years, we relied on Comet to clean these sinks. We sprinkled it on the entire sink, let it sit for a bit, and then scrubbed.

We recently discovered that Baking Soda is just as effective!! The fantastic thing about Baking Soda is that it is non-toxic. This is wonderful not only for our gray water holding tanks but also for the RV dump stations as well as the septic fields and municipal waste water treatment systems that are downstream from them.

It’s also really cheap!

Tips for cleaning an RV sink drain

White plastic RV sinks are prone to getting ugly stains.

Yuck!

We simply sprinkle it on the sink and then scrub the sink with a damp Scotch-Brite scrubbing pad.

What a great result — a wonderfully squeaky clean sink!

The drain plug also gets gummy, and we use an old toothbrush to scrub it clean with either baking soda and/or Murphy’s Oil Soap (a handy all around biodegradable cleanser).

In an RV that is used for dry camping a lot, like ours, the bathroom vanity sink drain can get really gross really quickly because in an effort to conserve fresh water not much clean water gets flushed down the drain.

This can result in foul odors in the sink drain, and it’s pretty unsightly too.

So, we do two things.

First, we scrub the inside of the bathroom sink drain with an old toothbrush. To get a longer reach down the drain, we taped our toothbrush to an old tent stake we had lying around. Anything long and narrow will work.

Tape an old toothbrush to a long stick to reach deep down the RV sink drain.

Scrub inside the sink drain.

We also scrub the sink drain plug.

Second, to keep the RV bathroom sink drain fresh smelling, we use Happy Camper Holding Tank Treatment which we’ve found is a particularly good deodorizer. We put scoop of powder in an old water bottle, fill it up with water and shake it well (the bottle gets warm as the enzymes get activated!), and then pour it down the drain.

Most of it goes into the gray water tank, but a small amount stays in the bathroom sink drain p-trap and does its magic there, killing off the offensive odors.

To keep our RV shower in tip-top shape, we clean the drain there as well. The biggest problem in our RV shower drain isn’t foul odors, because the shower drain gets flushed with lots of water everyday. Instead, the challenge with the RV shower drain is accumulated hair.

In a house, it’s easy enough to use a powerful cleanser like Drano to clean out any clogs caused by hair, but we don’t want strong chemicals like that sitting in our gray wastewater holding tank. Afterall, we want the enzymes and bacteria in the Happy Camper and Unique RV Digest-It holding tank treatment products we use to thrive and go to work breaking things down!

So, we use a long spring hook (and flashlight) to pull the hair out. It just takes a few minutes and then the drain is clear.

Some RV shower stalls may have drain components that can be removed for cleaning. Ours doesn’t.

Periodically, the RV shower wand gets crudded up with mineral deposits just like our RV sink faucets do. Again, we rely on white vinegar to clean up the deposits clogging the spray holes in the shower nozzle.

First, we pour the white vinegar through the shower wand to let it soak from the inside.

The RV shower wand can be cleaned with white vinegar.

Then we soak the shower wand’s face in a bath of white vinegar.

Tips for cleaning an RV shower wand

Put the RV shower wand face down in a white vinegar bath to clean all the little holes.

If we’ve let a little too much time pass, we’ll also use a toothpick to clean out each hole in the shower head. We use bamboo toothpicks because they hold up well in water. Ordinary wooden toothpicks tend to disintegrate when they get wet. A scribe also works well.

The before-and-after difference in the flow of water through the shower wand is startling. When half of the little holes are blocked from mineral deposits and the other half have an impeded flow, the water can feel like needles on your skin. After cleaning the wand, it is more like a waterfall.

Lots of RVers love the Oxygenics RV shower head. We don’t use it because it doesn’t work well with the low water pressure we use to conserve water since we dry camp every night, but for RVers who get water hookups a lot, these shower heads are extremely popular. Of course, in hard water areas, these shower heads will need periodic cleaning as well.

The RV toilet bowl rinsing wand is also subject to corrosion from mineral deposits, and after a while when we go to rinse the toilet bowl we find the water flow from the sprayer is restricted and funky.

The RV toilet sprayer wand gets clogged with minerals too.

Again, it’s easy to unscrew the end of the toilet spay wand, put it in a white vinegar for 20-30 minutes, scrub it a bit with a toothbrush, and then put it back on the wand.

RV toilet rinse wand cleaning

Unscrew the tip of the toilet rinsing wand and soak it in white vinegar to clean the holes.

As an aside, if you have energy leftover after cleaning all your RV sinks, faucets, drains and spray nozzles, a spray bottle filled with a water and white vinegar mixture is super for washing the windows. As I wrote this, some flies got in our trailer and Mark started spraying them when they landed on the window next to him using a spray bottle filled with water and white vinegar. Besides slowing them down and killing them, he was really impressed with how clean the window was when he finished!

So, these are a few of the things we do to keep our sinks and drains flowing smoothly in our life on the road in our RV.

We hope they help you too!

  1. As a certified House Cleaning Technician, there aren’t many things I recommend cleaning with baking soda or vinegar, but you covered two great uses! We need to do these jobs in our home on wheels too! Great post. Thanks!

  2. Nice post! One item that would help your hair in the shower drain problem is called a TubShroom. I’d never heard of it until my wife and I worked for Amazon last year in Campbellsville, KY. We must have picked hundreds of them during the three months we were there. For $13, it really keeps my wife’s hair from going down the drain.
