- Unplug the device before anything else.
- Blot the liquid with a clean, dry white cloth, working in from the edge.
- Keep the device away from heat, including dryers, irons and hot air.
- Test any cleaner on a hidden spot first, and stop if color transfers or changes.
Coffee on electronics is a tannin stain, and the device is the harder part of this job. A fresh splash on a casing or screen usually lifts with a dry cloth and then a barely damp one. If liquid has made its way inside, the stain is the smaller problem and a service provider should take over.
Power the device off and unplug it before you wipe anything, and keep liquid away from the ports and vents. Skip coffee machine cleaning tablets here, since they're made for a brewer's insides and can leave residue on a screen. If the device still acts up after it dries, get a service provider to look at it before you try more.

6 steps
Step by step
Step 1 of 6
Unplug and move the device
Unplug the device and remove all cables and external power before you touch the mark. Move it to a dry work surface and keep it away from dryers, irons and hot air for the whole cleaning.
Careful. Heat sets the mark and can make it permanent.
Step 2 of 6
Blot the coffee dry
Press a clean, dry white cloth onto the coffee and lift it away, moving to a fresh section of the cloth as it fills. Don't rub, because rubbing spreads the coffee and can damage the surface.
Step 3 of 6
Wipe with a dry cloth
Wipe the area with a soft, dry, lint-free cloth to pick up what blotting left behind. If the mark is gone and the surface looks clean, skip the next steps.
Step 4 of 6
Dampen the cloth for stubborn marks
If the mark remains, dampen a soft, lint-free cloth slightly, wring it out well, and wipe the mark again. Let the area dry fully before you turn the device on.
Careful. Keep moisture out of every opening, and never let the cloth drip.
Step 5 of 6
Clean screens with a screen cleaner
On a screen, put the cleaner made for screens onto the cloth, then wipe the mark gently. Let the screen dry before you use it.
Step 6 of 6
Lift hard smudges with alcohol
For a hard-to-remove mark on a hard, nonporous surface, wipe gently with a cloth moistened with 70% isopropyl alcohol or 75% ethyl alcohol. Test a hidden spot first, and stop if color changes.

Best products for coffee on electronics & screens
Choose a screen cleaner labeled for screens, and a 70% isopropyl alcohol wipe for hard smudges. Skip window cleaners and household sprays, since they're not for this surface.

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 mark should lift onto the cloth as you blot, and the surface should look even once it's dry. If the color changes or the surface looks different during a test, stop and don't continue.
What changes for yours
Adjust for your electronics & screens
Screens and displays
A display gets only the cleaner made for screens, and it goes on the cloth rather than the glass. Wipe gently, and let the screen dry before you turn it on.
Coffee with milk or cream leaves a greasy film as well as the stain, so the dry wipe matters most here. If the film still shows after both wipes, repeat the screen cleaner step once and check again.
Hard, nonporous casings
Hard, nonporous casings can take the alcohol wipe from the steps for a stubborn mark. Test a hidden spot first, and wipe gently rather than scrubbing.
If the test spot shows any color change, stop and go back to the dry and damp cloth steps. Give the alcohol wipe one gentle pass before deciding the mark is set.
Leather cases
Leather cases are not a place for alcohol, so stop at the dry wipe. Cleaning or conditioning leather can change its color, so don't try a cleaner on the mark.
Leather can stain from water, oil and dye transfer, so keep moisture to a minimum while you blot. If the mark still shows, leave it alone rather than guessing at a product.
Painted finishes
Painted parts can't take peroxide or oxygen cleaners, so the alcohol wipe is the strongest step here. Test a hidden spot first, and stop if the paint shows any change.
Keep the damp cloth barely moist, since moisture can get into openings. Anything beyond a gentle wipe is a question for a repair service, not a stronger cleaner.
Old, dried or set-in stains
A coffee mark that has sat for a while is harder to lift, but the same gentle steps still apply. Repeat the damp-cloth wipe a few times rather than pressing harder. Stronger products are not an option on this surface.
If the coffee has dried, the alcohol wipe is the step to use on a hard, nonporous surface, applied gently and only after a hidden-spot test. Keep the cloth barely moist so nothing gets into the openings.
If heat has already been applied, such as from a dryer or iron, the mark may not come out at all. When it stays after these steps, accept that it may be permanent and stop before you use anything harsher.
Vinegar, baking soda, peroxide and more
Do home remedies work on coffee on electronics & screens?
Most home remedies are built for fabric, glass or hard floors, not for electronics. On electronics, a dry blot and a barely damp cloth are the safe moves, and liquid never goes straight onto a screen.

What makes it worse
Mistakes to avoid
Don't spray the device
Spray any cleaner onto the cloth, never onto the device itself. Spray that lands on the device can run into openings and onto parts you can't see.
Don't submerge or soak it
Don't submerge the device or soak any part of it in cleaning agents. A soak gets moisture into openings and leaves the cleaner where no cloth can reach it.
Don't use bleach or peroxide
Chlorine bleach and hydrogen peroxide are out, and so are oxygen cleaners that contain peroxide. Leave all of them on the shelf for this stain, even if the mark looks stubborn.
Don't use household or window cleaners
Window cleaners, household cleaners, aerosol sprays, solvents, ammonia and acetone-based products are not for this surface. Dish soap counts as a household cleaner, so skip it too.
Don't use paper towels or scrubbers
Paper towels, abrasive cloths, abrasive cleaners and scrubbing pads can scratch the surface. Stick to a clean white cloth and a soft, lint-free cloth.
When to call a professional
If liquid gets inside the device, stop cleaning and get help from an authorized repair service for it. Wiping the outside can't reach what's inside, so don't keep at the surface once liquid has got in.
Questions
Does coffee stain electronics?
Yes, coffee is a tannin stain, and it gets harder to lift if it sits or dries. Unplug the device and blot it with a dry white cloth right away.
Can I use vinegar on a screen?
No, a screen should only get a barely damp cloth, so skip vinegar. For a screen, use a cleaner made for screens, applied to the cloth.
Can I use rubbing alcohol on my device?
Only for a hard smudge on a hard, nonporous surface, and only after a hidden-spot test. Keep it on the cloth, and skip it on leather.
What if the coffee has already dried?
Dried coffee is harder to lift, so repeat the gentle steps before trying anything else. If heat has already been applied, the mark may not come out at all.
Are coffee machine cleaning tablets safe to use near electronics?
The steps here are for the device's surface, not for a coffee machine. For the machine itself, see the Stainless Steel & Appliances guide.
Can I use a hair dryer to speed up drying?
No, hot air is one of the heat sources to keep away from the device. Let it air-dry at room temperature with the cables still out.
Can I clean a leather case the same way?
Not with alcohol, so stop at the dry wipe. Cleaning or conditioning leather can change its color, so leave the mark alone rather than guessing at a product.
