Cleaning products: baking soda, vinegar, and mild dish soap
Most sinks in RVs are made of plastic, which is lightweight but prone to scratches and stains. To keep your plastic RV sink in good shape, avoid using harsh chemicals, and opt for mild cleaning products like baking soda, vinegar, and mild dish soap. Here's a step-by-step guide on how to clean your plastic RV sink using these products:
Step 1: Baking Soda
Start by sprinkling baking soda generously onto the sink, coating the entire basin with a light layer. Baking soda is great for tackling hard water deposits, water spots, and grease. You can use a soft nylon brush, soft sponge, or paper towel to gently rub the baking soda into the sink's surface. Make sure to work in the direction of the grain to avoid scratching the plastic.
Step 2: Vinegar
Before rinsing the baking soda, spray undiluted white vinegar onto the sink. The baking soda and vinegar will react, creating a fizzing or frothing effect, which helps to brighten the sink. The vinegar also dissolves calcium deposits and removes water spots. Let the solution sit for 5-10 minutes.
Step 3: Rinse and Scrub
After the waiting period, thoroughly rinse the sink with warm water. If there are tough stains, create a paste with baking soda and water, and apply it directly to the stains. Gently scrub these areas with a soft-bristled brush or a soft sponge. You can also use a toothbrush for hard-to-reach areas.
Step 4: Dish Soap
For the final step, squirt liquid dish soap into the sink – the amount depends on the size of your sink. Fill the sink with hot water and let the soapy water sit for about 30 minutes to give the sink a thorough cleaning. Finally, drain the sink and rinse it again with water to remove any remaining stains or residue.
Additional Tips:
- For everyday cleaning, a mild soap and sponge can be used to wipe down the sink.
- To clean the faucets and handles, use a mild soapy solution and a soft cloth.
- Avoid using steel brushes, abrasive pads, or steel wool, as these can scratch the plastic.
- Regularly clean your RV sink drains with baking soda and vinegar to remove residue, clean the pipes, and keep them smelling fresh.
- Avoid pouring grease, butter, oil, or coffee grounds down the drain, as these can cause clogs.

Cleaning methods: using a soft-bristle brush, letting the solution sit
To clean a plastic RV sink, you should avoid using harsh chemicals, which can cause discolouration. Instead, mild dish soap and other mixtures that won't harm the surface of your sink are recommended.
One popular method for cleaning a plastic RV sink is to use a mixture of vinegar and baking soda. First, scrub the sink with baking soda, rubbing it towards the sink grain. Then, spray vinegar onto the sink and let the mixture sit for 5-10 minutes. Finally, rinse the sink with water. This method is effective at removing stains and brightening the sink.
Another option is to create a paste from vinegar and cream of tartar. Apply this paste directly to stains and gently rub it in with a soft-bristle brush. Let the paste sit for 5-10 minutes, then wash it off with warm water and dry the sink. This method is ideal for removing tougher stains.
For a simpler approach, you can try using toothpaste to remove stains from the surface of your plastic RV sink. Alternatively, you can use a store-bought cleaner, such as Bar Keeper's Friend, specifically designed to tackle stains and grime.
Remember to only use soft brushes when cleaning a plastic RV sink to avoid scratches. Also, pay attention to the drains and plumbing system, as clogged drains can cause significant issues during your trip.

Cleaning frequency: how often to clean your RV sink
A clean RV sink is essential for a pleasant and hygienic living space. It also helps maintain the durability of your RV's interior. Since RV sinks are prone to stains and clogs, they require regular cleaning and maintenance. Here are some tips to help you establish a cleaning routine for your RV sink:
Cleaning Frequency:
The frequency of cleaning your RV sink depends on several factors, including usage, the number of people, trip duration, and the type of waste. If your RV sink experiences high usage or frequently comes into contact with food debris, it will require more frequent cleaning. It is recommended to clean your RV sink at least once a week to prevent the buildup of bacteria and stains.
Additionally, the type of material your RV sink is made of will impact the cleaning schedule. For example, stainless steel sinks benefit from a quick rinse daily to prevent water spots and scratches, while porcelain sinks may not need cleaning as often but may require a deeper scrub due to their stain-prone nature.
Signs That Your RV Sink Needs Cleaning:
There are a few telltale signs that indicate it's time to clean your RV sink:
- Grime or ring formation around the sink's edge or bottom
- Unpleasant odours or musty smells when running hot water
- Pooling water or water spots around the faucet indicating soap scum buildup
- Slow drainage or backups, which could signal a clog in the pipes
Cleaning Methods:
To keep your RV sink in optimal condition, you can use a variety of cleaning methods:
- Baking soda and vinegar: Sprinkle baking soda on the sink, then spray with vinegar. Let it sit for 5-10 minutes before rinsing.
- Stain-removing paste: Create a paste with vinegar and cream of tartar. Gently rub it on stains and let it sit before washing off.
- Toothpaste: Toothpaste is a popular method for removing stains from plastic RV sinks.
- Enzyme cleaner: These cleaners use bacteria to eat away at food, grease, and clogs, keeping the drains clear.
Remember to avoid harsh chemicals that can damage the surface of your RV sink. Mild dish soap and natural mixtures are preferable to maintain the sink's condition and avoid discolouration.

Drain maintenance: keeping drains clog-free
A clean RV sink is essential for a pleasant and hygienic living space and can even enhance your overall RV experience. Keeping your RV drains clog-free is an important aspect of maintaining your RV sink. Here are some tips to achieve that:
Regular Cleaning and Maintenance
Regular cleaning and maintenance are crucial in preventing bigger plumbing problems down the road. It is recommended to clean your RV shower drain every few weeks to keep it clear of buildup and functioning well. You can use natural cleaners like baking soda and vinegar, which are gentler and safer for regular maintenance. To use this method, sprinkle three tablespoons of baking soda down the drain and follow it with a cup of white vinegar. This mixture will effectively dissolve any buildup and keep your drain smelling fresh.
Avoid Pouring Grease or Oils Down the Drain
Grease and oils are common culprits when it comes to clogging RV sinks. These substances can easily accumulate inside the pipes and form blockages that are difficult to remove without professional help. Therefore, it is important to avoid pouring grease or oils down the drain to prevent future clogs.
Catch Small Pieces of Food or Other Debris
Another tip to keep your RV drains clog-free is to be mindful of what you put down the drain. Try to catch any small pieces of food or other debris before they enter the pipe. Additionally, make sure to clean off all food particles from your utensils and dispose of food residue in designated bins.
Use a Plunger
If you encounter a clog, one of the easiest and most effective ways to unclog your RV sink is to use a plunger. Start by running some hot water down the drain, then place the plunger over the drain opening, ensuring a complete seal. Pump the plunger up and down with moderate pressure, then let it stay in place for a few minutes. This will help break up any debris causing the clog, allowing it to drain away more easily.
Check the Drain Vents
Clogged rooftop drain vents can cause your RV sink to drain slowly or even prevent it from draining entirely. Therefore, it is recommended to check these vents first when troubleshooting drain issues. Regularly cleaning the drain vents and ensuring they are clear of any obstructions is important for maintaining proper drainage.
By following these tips and performing regular maintenance, you can help keep your RV drains clog-free and ensure a smooth and enjoyable trip.

Store-bought vs. natural cleaning solutions
A clean RV sink is essential to enhance your overall RV experience. It ensures a pleasant and hygienic living space and helps maintain the durability of your RV's interior.
When it comes to cleaning your RV sink, you have the option of using store-bought cleaners or natural cleaning solutions. Let's explore both options in detail:
Store-Bought Cleaners:
Some people prefer the convenience of using store-bought cleaners, such as Bar Keeper's Friend, specifically designed to tackle stains and grime on stainless steel surfaces. These cleaners provide a hassle-free cleaning experience and are easily accessible. However, one of the main concerns with store-bought cleaners is the use of chemicals. Many RV owners try to minimise chemical usage to prevent residues from entering the grey water tank, which collects water from the drains. Additionally, harsh chemicals can damage the sink surface, especially plastic sinks, which are prone to staining and discolouration.
Natural Cleaning Solutions:
Natural cleaning solutions offer a chemical-free alternative to store-bought cleaners. Here are some popular options:
- Baking Soda and Vinegar: This dynamic duo is a powerful and natural solution for cleaning plastic RV sinks. The bubbling action created by combining these ingredients helps lift stains from the surface. Simply mix equal parts of vinegar and baking soda, apply the solution, and scrub gently with a soft brush. This method is safe and effective, and it also works well for cleaning drains and eliminating blockages.
- Toothpaste: Toothpaste is commonly used to remove stains from plastic RV sinks. It contains mild abrasives that can help lift stains without damaging the surface.
- Denture Tablets: Denture tablets are designed to clean artificial teeth, but they can also be used to clean plastic and acrylic sinks. They gradually dissolve stains, leaving your sink looking clean and fresh.
- Cream of Tartar: For stubborn stains, a paste made of vinegar and cream of tartar can be gently rubbed onto the affected areas.
In summary, while store-bought cleaners offer convenience, natural cleaning solutions provide a chemical-free approach that is safer for your RV sink and the environment. Natural alternatives like baking soda, vinegar, and toothpaste are effective stain removers and can help maintain the hygiene and durability of your RV sink.
