In this article, we will discover if or can you use WD40 on a hamster wheel.

Can You Use WD40 on a Hamster Wheel?

WD40 is a temporary solution to dealing with the problem of an aging or squeaking hamster wheel. The other methods used by members of the hamster community include oils such as vegetable oil or petroleum jelly as non-toxic options.

WD-40 can be a health risk if your hamster consumes even the slightest bit of it. A temporary stop-gap like WD-40 on a hamster wheel is not going to solve your problem for good.

The acidic crusty remnants of hamster urine in the components of the wheel might be the culprit, but overall, it’s best to update hamster toys including their wheels every few months to a year.

What Can I Use to Lubricate My Hamster Wheel?

Lubricating a hamster wheel becomes necessary after prolonged use and extended exercise session by your furry little pet.

The wheel gets crusty, rusty and squeaky. The acidic urine from the hamster may contribute to the deterioration of the wheel. Lubrication helps to make the wheel smooth once again.

You can use the following lubrication to smooth out the hamster wheel and reduce friction or squeaking that is coming from it:

  • Vaseline (petroleum jelly)
  • Coconut oil
  • Butter
  • Olive oil
  • Vegetable oil
  • Groundnut oil

Using WD 40 is not recommended for the toxic chemicals that are contained in it. A hamster is bound to the gnaw on the wheel just like anything else. You do not wish for your pet to lick or ingest the active ingredients in WD 40.

Should You Clean Your Hamster’s Wheel?

Yes. Regular maintenance of your hamster’s cage involves taking out the toys and hamster wheel as well for a clean up.

The hamster wheel can get crusty with dried urine stains that are harmful when attracting bacteria or insects.

Hygienic issues lead to health problems and it goes without saying that a clean cage is a better overall space for a health hamster to thrive.

Will My Hamster Be Okay Without a Wheel for One Night?

A hamster needs to remain active in a confined space. We keep these creatures comfortable in captivity and provide some much love, attention, food and warmth for them, but we should care about their level of activity as well.

Leaving your hamster without a wheel for anything longer than 3-7 days could lead to obesity or other more health issues. Take out the wheel, clean it up, lubricate it or purchase a new one that will hopefully arrive in a day or two.

Can You Oil a Hamster Wheel?

Yes. You can apply safe oils that will not harm your hamster when you are attempting to clean or lubricate a hamster’s wheel. It’s best to to stick with natural substances like coconut oil or vegetable oil that are safe for hamster consumption than opting for industrial lubricants.

We do not recommend using WD-40 for a hamster wheel because of the tendency for rodents to gnaw on everything in sight and make contact with items with their mouths. Ingesting toxic chemicals from adding toxic oil to lubricate the wheel is not advised.

Why Did My Hamster Pee in Her Wheel?

Hamsters get excited on their wheels and pee will escape. Another reason why your hamster would decide to pee on the wheel is to mark the territory so that no one one else could play with it.

The act of soiling a wheel with feces or urine could become a habit that causes the wheel to age, get rusty or squeaky.

A final reason could be that a new wheel is intimidating and causes your hamster to pee on it out of fear when it spins too fast.


Using WD-40 on any surface that a hamster comes into contact with poses health risks. Spraying WD 40 to lubricate a hamster wheel will surely come into contact with your hamster’s body or mouth during exercise and gnawing.

A hamster might get some of this lubricant on its feet and lick it off. There are plenty of more hazardous items worse than WD 40 that hamsters could ingest and get sick, but there are safer options as well like petroleum jelly, coconut oil or vegetable oil. Consider a natural option to lubricate the wheel instead of using WD 40.
