The best way to remove urine stains on your rabbit’s cage is by spraying vinegar mixed with water on the area. Vinegar dissolves the calcium carbonate in your rabbit’s urine, you know that white stuff that forms at the bottom of their cage.

If the stains won’t come off by using vinegar mixed in with water, you can try to spray pure vinegar and leaving it for 20 minutes. Then, wipe it with a brush.

You could also use stain removers like OxiClean or Clorox to remove those calcium carbonate stains.

Another option is to use dish soap + scouring pad, while this method would take longer than the other because dish soap doesn’t have the same dissolving effects of vinegar and stain removers, it should still work.

Just put some dish soap on the affected area and leave it for 20 minutes then scrub with a scouring pad.

What is the white stuff in my rabbit’s cage?

The white stuff that hardens in the bottom of your rabbit’s cage is called calcium carbonate. It’s what happens when your rabbit is ingesting large amounts of calcium.

Rabbits primarily excrete their excess calcium in their urine leaving the white stuff you see in their litter tray. Too much calcium in your rabbit’s diet could also lead to urinary stones.

You can prevent this by changing your rabbit’s diet. If your rabbit is on a diet of alfalfa hay, try changing it to timothy hay. Timothy hay contains less calcium

How to remove dried urine stains from your rabbit’s cage?

Removing the dried urine stain from your rabbit’s cage can be done with some simple household items you have right now. But remember that it also depends on what kind of plastic your litter tray is.

Low-quality litter trays are mostly made of cheap plastic that bonds with the urine stain making it hard or almost impossible to remove without scratching the plastic itself.

Use vinegar and water.

Possibly the best and most accessible cage cleaner for rabbits on this list. Not only is vinegar safe for rabbits, but it’s also in everyone’s home.

It also works great for urine buildup because vinegar dissolves the calcium carbonate in your rabbit’s urine.

Just mix the vinegar with water and spray it on the affected area. Leave it for 20 minutes and wash it off. You can leave the cage/litter tray in the sun for 20 minutes to disinfect and dry it.

Use stain remover (OxiClean, Clorox, etc…)

If you have a stain remover lying around, like OxiClean and Clorox, you can use it to remove the urine stains from your rabbit’s cage.

Just remember to dry it completely before putting your rabbit inside the cage.

Make sure that your rabbit doesn’t have any contact with any cleaners in the house because some are toxic to rabbits.

Use Dish soap + Scouring pad

If you are on a tight budget, you can use a simple dish soap and scrub it with a scouring pad. While it would take longer to remove the stains, it should work because the scouring pad would grind off the calcium carbonate build-up.

Unless your rabbit’s litter tray is made out of cheap plastic, then you would need a more specialized cleaner like a stain remover or vinegar.
