Quick answer: To clean a cat water fountain, unplug it, empty it, take it fully apart, wash every piece (including the pump) in warm water with a little unscented dish soap, scrub corners with a small brush, rinse well, and put in a fresh or rinsed filter. Do a quick rinse and refill every few days and a full deep clean about every one to two weeks. If you want a fountain that makes this easier, I like the dishwasher-safe PetSafe Drinkwell Platinum, the PETLIBRO Dockstream 2 with its pump-free design, and the stainless steel Neareal HY-F1.
A fountain only keeps water fresh if the fountain itself stays clean. Hair, food crumbs, and mineral scale build up fast. Below is the routine I recommend, plus three fountains that are easier to keep clean. I have not tested these fountains myself; my picks are based on manufacturer specifications and verified owner reviews.
What You Need
- Unscented, mild dish soap
- A soft sponge and a small bottle or pipe brush (an old toothbrush works for the pump)
- White vinegar for mineral scale
- A replacement filter, if yours is due
How to Clean a Cat Water Fountain, Step by Step
1. Unplug and empty it
Always unplug the fountain before you touch the pump, then pour out the old water.
2. Take it fully apart
Remove the lid, the spout or flower top, the filter, and the pump. Most pumps have a cover that pops off so you can reach the small impeller inside. Hair and slime collect here.
3. Wash the bowl and parts
Use warm water and a drop of unscented dish soap. Scrub the bowl, the corners, and any channels with the brush. Strongly scented soaps can leave a smell that puts some cats off drinking.
4. Clean the pump
Brush the pump housing and the impeller gently under running water, and push water through the intake. Do not put the pump in the dishwasher unless your manual says it is safe.
5. Remove mineral scale
If you see white crust, soak the affected parts in a mix of equal parts white vinegar and water for 15 to 20 minutes, then scrub. Rinse very well afterwards so no vinegar taste is left behind.
6. Rinse, replace the filter, and refill
Rinse every part until no soap remains. Rinse or replace the filter according to the manufacturer’s schedule, reassemble, fill with fresh water, and plug it back in. Make sure the water is above the minimum line so the pump does not run dry.
How Often Should You Clean It?
As a simple routine, I suggest topping up with fresh water daily, emptying and rinsing the bowl every few days, and doing the full deep clean above every one to two weeks. Clean more often if you have several pets, a cat that drops food in the water, or hard tap water. Filter schedules vary by brand, so follow your manual for that part.

How to Choose an Easy-to-Clean Fountain
Count the parts
Every extra piece is something to scrub. Fewer parts and wide openings make cleaning faster.
Check the material
Stainless steel and ceramic are easier to keep smooth and clean than plastic, which can scratch over time. My guide to the best stainless steel cat water fountains covers more options.
Look for dishwasher-safe parts
If you know you will not hand-wash every week, a dishwasher-safe fountain is the most realistic choice.
Factor in filter cost and availability
You will replace filters regularly for as long as you own the fountain, so pick a brand whose filters are easy to find. For a wider look at the category, see my best cat water fountain roundup or browse all pet water fountains.
Health Note
A dirty fountain can put some cats off drinking. If your cat suddenly drinks much more or much less than usual, talk to your veterinarian. This article is general care advice, not medical or veterinary advice.
Final Thoughts
Cleaning a cat water fountain is not hard: empty it, take it apart, wash everything including the pump, descale when needed, and refresh the filter.

FAQs
Can I use vinegar to clean a cat water fountain?
Yes, diluted white vinegar is a common way to remove mineral scale. Rinse every part thoroughly afterwards so no smell or taste remains.
Can I put my cat fountain in the dishwasher?
Only if the manufacturer says so. The PetSafe Drinkwell Platinum is listed as top-shelf dishwasher safe, but pumps and electrical parts should usually be cleaned by hand.
What is the pink slime in my cat’s fountain?
The pink or slimy film is usually a bacterial biofilm. It means the fountain needs a full clean, including the pump, and probably a more frequent cleaning schedule.
How often should I change the filter?
It depends on the brand and how many pets use the fountain. Follow the schedule in your manual, and change it sooner if the water looks cloudy or the flow slows down.
