First few minutes
Just happened? Do this first
- Put on gloves and don't shake the device or its cables.
- Unplug the device and lift off loose droppings with a dry, lint-free cloth.
- Don't run water over it; a barely damp cloth is the most it can take.
- Wash your hands with soap and water afterward.
Poop on a device is a body-soil stain, but electronics can take very little moisture, so every step has to keep liquid away from the openings. Lifting the droppings off before anything touches the spot matters, because pressing them in can push grime into the gaps. Fresh residue comes off with almost no moisture, while dried-on marks need more patience and a careful touch.
For mouse poop cleanup around cords and vents, start with a dry microfiber cloth. Only move to a barely damp corner of that cloth for keyboard gaps or trackpad edges, and never spray the device directly. If mouse droppings have gotten into a vent or port, stop and let a technician handle it rather than pushing deeper.

6 steps
Step by step
Step 1 of 6
Put on gloves and unplug
Pull on rubber or disposable gloves before you touch the device. Unplug it and remove all cables and external power first, so nothing is live while you clean.
Tip. Move the cables out of the way so they don't pick up the mess.
Step 2 of 6
Lift off the loose droppings
Use a soft, dry, lint-free cloth to gently lift off any solids. Work from the outside of the mark inward so you don't push it deeper into the surface.
Step 3 of 6
Wipe with a barely damp cloth
If the mark remains, dampen a soft, lint-free cloth until it is only slightly damp, then wipe the spot. Follow up right away with a dry part of the same cloth.
Tip. Wring the cloth out well before it touches the device.
Careful. Don't submerge the device or get moisture into any ports, vents or other openings.
Step 4 of 6
Clean screens with cleaner on the cloth
For a screen, apply a cleaner intended for screens to the cloth, then wipe the display gently. On the rest of the device, keep using the damp cloth.
Careful. Never spray cleaner directly onto the device; spray the cloth instead.
Step 5 of 6
Use the alcohol wipe on hard smudges
For hard-to-remove smudges on hard, nonporous parts, gently wipe with 70% isopropyl alcohol, a 75% ethyl alcohol wipe, or a disinfecting wipe. Use it on the hard parts only, and test an inconspicuous spot first.
Step 6 of 6
Wash your hands and check for liquid
Wash your hands with soap and water as soon as you finish, even if you wore gloves. If liquid got inside the device at any point, stop cleaning and get professional help.

Best products for poop on electronics & screens
Look for a cleaner labeled for screens and a 70% isopropyl alcohol wipe for hard parts. Skip any product labeled as bleach or containing acetone.
Amazon Basics Microfiber Cleaning Cloths
How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on electronics & screens, and its directions fit the steps above.
Finished the steps? How does it look?
Nice work. Let it dry completely and check it again in good light. Here is what done looks like:
How to tell it's really gone →A faint mark usually needs one more round, not a stronger product.
If the stain was already dried or set, the method changes.
Old, dried or set-in stains →When to call a professional →How to tell it's working
The spot is gone when the cloth comes away clean and the surface looks even, with no tacky film or dull patch left behind. If a mark still shows after the damp and alcohol passes, stop and don't keep rubbing the same spot.
What changes for yours
Adjust for your electronics & screens
Screen or display
Put the screen cleaner on the cloth, never on the display itself, and wipe gently until the mark lifts. Don't use household cleaners or window cleaners on a screen.
If the mark is still there after one pass, repeat with a fresh area of the cloth rather than pressing harder. Keep the cloth barely damp so no moisture seeps into the edges.
Laptop keyboard or trackpad
Keys and trackpads are hard, nonporous parts, so the 70% isopropyl alcohol wipe is the right step once the loose droppings are gone. Keep it out of the key gaps and any vents.
Wipe one key or a small patch at a time, and let it dry before you judge the spot. Keep the laptop off and unplugged until everything is dry.
Router, modem or cable box
Vents and ports are openings, so the damp cloth stays off them entirely. Wipe the outside with the soft, lint-free cloth and lift loose droppings from the vents gently.
If droppings have worked into a vent, don't poke at it with anything hard. Unplug the box and give the vent one more dry wipe instead.
Leather or fabric case
Leather can change color when it's cleaned, so test an inconspicuous spot before anything damp goes near it. Use only the dry lint-free cloth to lift the droppings, and skip the damp cloth until the test spot looks right.
If the case is fabric or another material, use the dry cloth only and leave the alcohol wipe out. Water and oil can stain leather, so keep any moisture to a minimum.
Cables and power cords
Unplug the cord and wipe its length with the dry, lint-free cloth first. Use the damp cloth on the plug end only if the mark persists, and keep it away from the connector.
Don't soak a cord or let it sit in any cleaning solution. Moisture in the connectors is what the device can't take.
Old, dried or set-in stains
If the droppings have been sitting on the device for a while, the mess is harder to lift, but the same rules apply. Don't soak it or reach for a stronger product, because the device can't take those.
For dried droppings, lift off the loose crust with a dry, lint-free cloth first so you don't push it deeper. Then work the spot with a barely damp cloth, switching to a clean section of cloth as it picks up the mess.
If a mark still remains after that, use the 70% isopropyl alcohol wipe on hard, nonporous parts only, testing an inconspicuous spot first. Some marks in seams or on screens won't come out at home, and that is the point to stop and get professional help.

Do home remedies work on poop on electronics & screens?
Most kitchen and laundry remedies are off the table for electronics, since the device can't take bleach, soaks, household cleaners or abrasives. An alcohol wipe on hard smudges is the one remedy worth trying; skip the others.

What makes it worse
Mistakes to avoid
Don't use bleach or hydrogen peroxide.
Both are off the list for this device, so don't reach for them even on a stubborn mark. Stick to the cloth methods and the alcohol wipe on hard parts.
Don't shake the item or handle it bare-handed.
Shaking a soiled item spreads the mess and can push it into more openings. Bare hands put the droppings in direct contact with your skin, so keep the gloves on until everything is wiped and washed.
Don't use household cleaners or window cleaners.
Dish soap, window cleaners, aerosol sprays, ammonia and cleaners containing acetone are all off the list for displays. A spray or soapy cloth can leave residue and moisture where you don't want them.
Don't scrub with paper towels or abrasive cloths.
Paper towels and abrasive cloths can scratch the surface and dull the finish. A soft, lint-free cloth does the job without that risk, even on the hard parts.
When to call a professional
If liquid has made its way inside the device, a professional repair technician is the right next step. Leave the openings alone, since moisture inside is the one thing the device can't take.
Questions
Can I rinse mouse poop off electronics with water?
No. Running water over the device can get into the openings, and the device can only take a soft, slightly damp, lint-free cloth. Lift the droppings with a dry cloth, then wipe the spot lightly with a damp one.
Is bleach safe for mouse droppings on a device?
No. Bleach and hydrogen peroxide are both off the list for electronics, even on a stubborn mark. Stick to the dry cloth, the damp cloth and the alcohol wipe on hard parts.
Do I need to unplug the device first?
Yes. Unplug it and remove all cables and external power before you clean anything. That keeps you safe while you work and keeps moisture away from the power ports.
What if the droppings have dried on?
Lift off the loose crust with a dry, lint-free cloth first, so you don't push it deeper. Then work the spot with a barely damp cloth, moving to a clean section as it picks up the mess.
Can I use rubbing alcohol on my screen?
Don't. Screens get a cleaner intended for screens, applied to the cloth. The 70% isopropyl alcohol wipe is for hard, nonporous parts only.
What should I do if liquid got inside?
Stop cleaning right away, because the device can't take moisture in its openings. Don't try to clean the inside yourself or keep wiping at the spot. Take it to a professional repair technician who can check it properly.
Can I use dish soap or vinegar on electronics?
No. Both are household products, and household cleaners are off the list for this device. Use the dry and damp lint-free cloths instead, and the alcohol wipe only on hard parts.
