How to clean a litter box: A simple and easy step-by-step guide

Maintaining a clean home environment requires a simple and consistent litter box cleaning routine. Knowing how to clean a litter box properly can help control odors and make daily maintenance easier.

Why Is Regularly Cleaning a Litter Box Important?

Keep the litter box clean and comfortable

A regularly cleaned litter box provides a dry and comfortable experience. If waste accumulates for too long, unpleasant odors can quickly build up and spread around the room. Keeping it clean can prevent stale smells from seeping into surrounding furniture, carpets, and walls.

Make daily maintenance easier

Scooping litter for a minute or two each day is very easy. But if you skip it for several days, waste and used litter can become harder to remove, making the cleaning process more time-consuming. Requiring a lot of time and effort to scrub. Consistent daily maintenance will keep this chore easy.

Prevent Cat Litter From Sticking to the Bottom and Clumping

When moisture remains at the bottom for too long, used litter can stick to the surface and become difficult to remove. Regular cleaning can prevent this residue from sticking to the container walls, saving you the trouble of scraping the plastic or metal surfaces later.

What do I need to prepare for cleaning the litter box?

Cat litter scoop

Choose a sturdy litter scoop with openings that work well with your type of cat litter. Metal scoops are less prone to bending when breaking up stubborn clumps and are more efficient.

Garbage bags or special cleaning bags

Keep small garbage bags, poop bags, or special cleaning bags readily available next to the litter box for waste collection and disposal when scooping litter each day.

Mild dishwashing liquid

Ordinary unscented or lightly scented dish soaps can effectively break down grease and grime.  Mild dish soap can help remove dirt and residue from the litter box. Please always refer to the original material care instructions from the cat litter box manufacturer before cleaning.

Warm water

Warm water dissolves dried residue faster than cold water, significantly reducing scrubbing time.

Soft sponge or cleaning cloth

Using a soft, non-abrasive sponge or microfiber cloth can protect the clean interior of the litter box. Never use steel wool or abrasive dish sponges, as scratches on the plastic surface can create traps for dirt and odors.

Fresh cat litter

When adding new sand, maintain a thickness of approximately 7 to 10 centimeters (3–4 inches) to provide enough depth for effective clumping and odor control.

Optional auxiliary cleaning tools

• Plastic scraper: Used to gently loosen dry sand blocks at the edges without damaging the basin.
• Kitchen paper towels: Used to quickly dry the surface before pouring in new sand.
• Anti-litter mat (litter drop mat): Placed at the outlet of the litter box to intercept loose particles brought out by the cat’s claws.

Detailed steps for cleaning a cat litter box

Step 1: Empty the old cat litter box

Pour all the old litter from the litter box into a thick garbage bag, tie the bag tightly, and dispose of it in your household trash. Never flush cat litter down the toilet unless the product label specifically says it is safe to flush.

Step 2: Remove or loosen any residue stuck to the bottom.

Use a soft scraper or litter scoop to gently loosen the dried residue stuck to the bottom or sides of the litter box. Be careful to be gentle and avoid scratching the bottom of the box.

Step 3: Thoroughly clean up any remaining dust

Shake or wipe out any remaining dust and debris over the trash bag.

Step 4: Rinse with warm water

Take the litter box to the sink, bathroom, or outdoor washing area and rinse off the surface dust with warm water first.

Step 5: Wash with a mild detergent

Add a few drops of mild dish soap, pour in warm water, and use a soft sponge to thoroughly clean the inner, outer, and rim walls of the litter box.

Step 6: Focus on scrubbing the corners and crevices.

Pay special attention to cleaning the four inner corners, the edges and grooves, and the seams, as these areas are most prone to accumulating liquid residue. Gently scrub with a sponge in circular motions to remove thin film-like dirt.

Step 7: Rinse thoroughly

Rinse thoroughly with water until no foam or slippery feeling remains. Detergent residue on the surface may attract dust more easily.

Step 8: Dry the Litter Box Completely

Thoroughly dry the inside and outside of the litter box with kitchen paper towels or a dry cloth, and let it air dry in a well-ventilated area for 5–10 minutes to ensure that all moisture has evaporated. If the box is still damp, the fresh litter may absorb the moisture and begin to clump or stick to the bottom.

Step 9: Add fresh cat litter

Pour in fresh cat litter, filling it to a depth of about 7 to 10 centimeters. Replace the top cover, filter, or baffle, and put the litter box back in its original position.

How to clean the litter box without making a mess

Choose an Easy-to-Clean Location

Place the litter box on a flat surface such as tile, wood, or laminate flooring, rather than on a thick carpet. A flat surface is easier to sweep or vacuum if litter is spilled.

Lay sand-proof mats underneath

Place a textured litter mat in front of the litter box entrance. Double-layered honeycomb mats or washable rubber mats can effectively trap litter brought out by claws, preventing it from scattering throughout the house.

Keep cleaning tools within easy reach.

Store the litter scooping tools and litter bags in the small basket next to the litter box. This keeps everything you need within easy reach and saves time during daily cleaning.

Clean up litter immediately

Clean up any stray cat litter with a small broom immediately. If loose litter is left on the floor, it can be tracked around the house and make cleanup more difficult.

Avoid adding too much cat litter

If the litter is poured too full, it will easily splatter when the cat scratches. Maintain a moderate thickness of 7 to 10 centimeters, leaving enough buffer space at the edges .

How to eliminate odor from a cat litter box

Regularly clean up excrement and clumps.

Daily cat litter removal is the most effective way to control odors. Timely removal of clumps can prevent stale smells from spreading into the air.

Regularly clean the entire surface instead of just adding new sand.

Simply adding new sand can only temporarily cover up the old particles at the bottom. Only by thoroughly changing the sand and washing the pot at a fixed schedule can you eliminate environmental odors at their source.

Make sure to dry thoroughly after washing.

Residual moisture can cause newly added cat litter to quickly become damp and spoil. Before adding more litter, always ensure the litter box is completely dry.

Choose materials that are easy to clean and do not easily absorb odors.

Non-porous materials (such as stainless steel or high-quality scratch-resistant plastic) are more durable and less likely to absorb odors than old plastic basins that are already full of scratches.

Keep the surrounding environment clean

Using pet wipes to wipe down the walls, baseboards, and litter mat around the litter box weekly. Odors often accumulate not only on the litter box itself but also on the surrounding surfaces.

How often should the litter box be cleaned?

Cleaning frequency	Cleaning Project	Specific operations
daily	Sand removal and spot cleaning	Remove clumps and excrement; sweep up loose sand from the sand mat.
weekly	Spot cleaning and sanding	Wipe the outer edge, replenish the used cat litter, and shake off the dust from the litter pad.
Every 2–4 weeks	Deep cleaning	Empty all the cat litter, wash it with detergent and warm water, dry it thoroughly, and then replace it with brand new cat litter.

Daily litter box maintenance

Scoop solid waste and liquid clumps 1 to 2 times every day. According to wellness guidelines from the American Veterinary Medical Association (AVMA), maintaining daily hygiene is vital for both house cleanliness and feline comfort.

Weekly maintenance

Check the litter thickness and add new litter, maintaining a height of 7–10 cm. Wipe the edges and outer walls of the lid with a damp cloth to remove any loose dust.

When is deep cleaning needed?

• Daily: Scoop waste
• Regularly: Top up or replace litter according to the litter product’s instructions
• Every few weeks or as needed: Empty and wash the litter box

How to clean different types of cat litter boxes

Cleaning tips for cat litter boxes made of different materials
Plastic cat litter box	Use a soft sponge to avoid scratches; replace the pot with a new one when the surface is severely aged.
Enclosed litter box	Remove the top cover for cleaning, focusing on scrubbing the inner top seams and movable door panels.
Stainless steel cat litter box	The surface is smooth and non-porous, extremely durable, and can be cleaned with water without easily leaving residue or odors.
Fully automatic cat litter box	Before cleaning, be sure to unplug the power supply. Wipe the sensors with a dry cloth. Only clean the removable waste collection box and inner chamber.

Plastic cat litter box

Plastic is lightweight and widely used, but it is easily scratched by hard spatulas and rough brushes. Always use a soft sponge when cleaning. If the inner surface becomes heavily scratched or damaged, consider replacing the litter box.

Enclosed litter box

Enclosed litter boxes tend to accumulate moisture and dust. When cleaning, be sure to remove the top cover latches and rinse the inside of the dome and the sliding door separately, as these areas easily absorb moisture and dust.

Stainless steel cat litter box

The stainless steel surface is smooth and non-porous, making it extremely difficult for cat litter and dirt to stick. It can be quickly rinsed clean with dish soap and warm water, and is generally less likely to absorb odors or develop deep scratches than plastic.

Fully automatic cat litter box

Power must be disconnected before cleaning electric cleaning equipment. Never immerse the machine body containing motors or electronic components directly in water. Only remove and wash the parts that the manufacturer identifies as washable. The photoelectric sensor area can be gently wiped with a dry microfiber cloth.

Avoid these common litter box cleaning mistakes

Adding new sand directly without cleaning the old sand

Adding new litter directly onto old, broken litter will trap odors at the bottom. Make sure to thoroughly remove the bottom litter during a deep clean.

Leaving Wet Litter Stuck to the Bottom

If you neglect the wet sand stuck to the bottom when shoveling sand, it will eventually harden into lumps that are extremely difficult to clean later. You should remove any clumps stuck to the bottom during daily scooping.

Using overly harsh cleaning agents

Avoid using strong acids, alkalis, bleach, or industrial cleaners with overly strong fragrances. Strong fragrances or cleaning residues may make the litter box less appealing to some cats. Regular, mild dishwashing liquid is perfectly adequate.

Adding Fresh Litter Before the Box Is Completely Dry

Even a tiny amount of water droplets can cause newly poured cat litter to clump and become sticky upon contact. After washing, spend an extra minute thoroughly drying it with a towel.

Ignore corners and edge gaps

The four corners of the litter box are where liquids are most likely to accumulate and solidify. When scooping litter daily, make sure the scoop reaches all four corners.

Wait until the odor becomes very strong before cleaning.

If you can smell the litter box from as far away as the living room, it means deep cleaning has been severely neglected. Establishing a regular litter box cleaning routine can prevent odors from developing.

Practical tips to make litter box cleaning easier

Cleaning supplies can be stored in a centralized manner.

Prepare a small storage basket to hold the litter scoop, trash bags, small broom, and paper towels together. Storing them together saves preparation time each time you clean a litter box.

Clever use of anti-sand pads

Placing a large, double-layered litter mat at the exit .can catch much of the litter that gets tracked out of the box, significantly reducing the amount of floor cleaning work.

Choose an easy-to-clean litter box.

Replacing it with a stainless steel litter box or an open-top box with rounded inner corners reduce hard-to-reach areas and make scooping easier.

Develop simple daily habits

Integrate sand shoveling into your daily chores—for example, scoop the litter before taking out the trash each morning. Make routine maintenance a natural habit, and it won’t feel tedious.

Cleaning tips based on real pet ownership experience

What kind of litter box is the easiest to clean?

In everyday use, litter boxes with rounded inner corners are much easier to scoop because waste is less likely to get trapped along the edges. The rounded, seamless bottom edge allows the litter scoop to slide smoothly without getting stuck at corners.

Small habits to reduce cleaning time

Hang a small hand broom next to the storage basket. Spend a few seconds each morning sweeping around the sand mat to prevent loose sand from being trampled everywhere.

Tips for dealing with stubborn sticky bottoms

If the litter is stuck tightly to the bottom of the litter box, do not try to scrape it off with a hard object. First, empty the loose litter, then pour a little warm water and dish soap into the sticky area and soak it for 5 to 10 minutes. Once the residue has absorbed the water and softened, you can gently wipe it off with a sponge.

Make deep washing no longer a hassle

Choose a well-lit area with a warm water tap for a thorough cleaning. Prepare a set of dedicated cleaning sponges (strictly separate from kitchen utensils) for both hygiene and efficiency.
