- Blot up fresh milk and scrape off thick formula.
- Rinse in cold water to start.
- Act fast; the longer it sits, the harder it is to lift.
Milk and formula on glass bottles and ceramic dishes sets quickly once heat touches it, because the protein cooks onto the surface. Fresh residue rinses off easily in cold water, but glass and ceramic can crack under sudden temperature changes, so the hot tap stays off until the stain is gone. A bottle that sat overnight can still come clean, though it takes longer and may need a second round.
Bottle nipples hold residue in their small ridges, so give those a closer look than the bottle body. A soft microfiber cloth gets into the grooves without scratching the plastic or glass. If residue still clings after a second wash, rinse again rather than scrubbing harder.

6 steps
Step by step
Step 1 of 6
Blot up and scrape off
Blot fresh milk with a clean cloth or paper towel, pressing rather than rubbing. Gently scrape off any thick formula or dried milk so the rinse can reach what's left. Fresh protein stains come out far more easily, so start now.
Step 2 of 6
Rinse with cold water first
Rinse the bottle or dish under cold running water to clear away most of the milk. If there is a lot, let it sit briefly in cold water to loosen what's left before the next step.
Step 3 of 6
Wash with mild soap
Once most of the milk is rinsed away, wash with mild soap, warm water and a soft cloth. Work over every part the milk touched, including the rim and the threads on a bottle.
Step 4 of 6
Use a non-abrasive cleanser
On glass or ceramic dishware, apply a non-abrasive cleanser and work it in with the soft cloth. For heavy dried-on milk, let the cleanser dwell 3 to 5 minutes per its label before you scour. If you need to scour, use only a plastic or nylon pad and keep the pressure light.
Tip. Test any new cleaner on a small, inconspicuous area first.
Careful. Fluorine compounds damage ceramic, glass and stone, so check the label before you use a cleanser.
Step 5 of 6
Rinse every trace away
Rinse thoroughly with clean water after any cleaner you used. Alkaline cleaners may need several rinses before the piece is fully clear.
Step 6 of 6
Check before drying
Look at the spot in good light once the piece is dry. If any milky film or dull patch remains, repeat the cold rinse and the washing step before you move on.
Careful. Heat from a dryer sets the stain, so keep it out of the dryer until it's gone.

How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on dishes & mugs, 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
You'll see the milky film thin out with each rinse, and the cloth should pick up less white as you go. Look at the piece under bright light once it's dry, because wet glass hides a faint film. If the cloudiness holds after a second soak, the protein has set and it's time for the old-stain approach.
What changes for yours
Adjust for your dishes & mugs
Baby bottles
Rinse the bottle in cold water as soon as the feed is over, since milk and formula are easiest to lift while fresh. Before you scrub, check what the bottle is made of, because the cleaning is only meant for glass and ceramic.
If you can't tell what the bottle is made of, don't guess. Wash it by hand with mild soap and a soft cloth, and skip any pad or abrasive cleanser.
Bottle nipples
Cleaning advice for glass and ceramic does not tell you how a nipple will react to a cleaner. Rinse the nipple in cold water right after the feed, then wash it with mild soap and a soft cloth.
Don't scrub a nipple with a pad or abrasive cleaner, and rinse well so no soap is left in the openings. If a mark stays after a rinse and wash, leave it rather than pushing harder, and check the nipple before each use.
Old, dried or set-in stains
Old milk takes more work than a fresh spot, because the longer it stays, the harder it is to lift. Expect the first round to loosen only part of it.
Dried milk needs a crust scraped off before anything else. Work a non-abrasive cleanser into the spot, then rinse it well before you judge the result. If the piece has been through a dryer, the heat has probably set the stain more firmly, so plan on more than one round.
Repeat the cold rinse and the cleaning steps, rinsing well after each round. If the spot is still visible after several rounds, it's realistic to accept a faint mark rather than push harder on glass or ceramic.

Do home remedies work on milk on dishes & mugs?
Most remedies people reach for on milk don't suit dishes or bottles. Cold water and mild soap handle milk on dishes and bottles, so leave the other remedies alone.

What makes it worse
Mistakes to avoid
Don't use hot water on the milk
Heat cooks the milk protein and makes it set, so a hot rinse can turn an easy stain into a harder one. Keep the first rinse cold, and wait until most of the milk is gone before any warm water.
Don't let glass or ceramic soak for long
Glass and ceramic should not stand in water for a long time, so an overnight soak isn't the answer. A brief cold soak is enough, and the soap and cleanser do the rest.
Don't scrub glass or ceramic with metal
Scratches dull the finish and give milk film more places to cling, so every later wash works harder. Stick to a soft cloth, or a plastic or nylon pad, paired with a non-abrasive cleanser.
Don't move a warm bottle straight into cold water
A bottle that just came out of a warm wash can crack when it meets cold water or a cold counter. Let it come down to room temperature, then rinse it with cold water as usual.
Don't use fluorine cleaners on dishes
Fluorine compounds damage ceramic, glass and stone, so they don't belong anywhere near a bottle or plate. Read the label on any tile or bathroom product before it goes near your dishes.
When to call a professional
Milk on dishes rarely needs a professional, but if a mark survives the soak and several rounds of mild soap, stop before you try anything harsher. Tell whoever you bring in that it was milk, how long it sat, and which cleaners you've already used.
Questions
How soon should I treat a milk stain?
As soon as you can. Fresh protein stains come out far more easily, and the longer milk stays on the surface, the harder it is to lift.
Can I still remove milk that has dried on?
Usually, but it takes longer. Scrape off the crust first, then work a non-abrasive cleanser into the spot before rinsing, and expect more than one round.
Can I use dish soap on a bottle?
Yes. A mild soap in warm water is the washing step, used once the cold rinse has taken off most of the milk. Rinse it out fully so no soap film is left.
What if one round doesn't clear it?
Repeat the cold rinse and the washing step rather than adding heat. Old milk often needs several rounds, and it's better to repeat gently than to push harder.
How soon should I clean a bottle nipple?
Right after the feed, if you can. Fresh milk is far easier to lift than milk that has dried in the openings, so a quick rinse saves scrubbing later.
How do I know the stain is gone?
Check it in good light once the piece is dry. If a milky film or dull patch is still there, the stain isn't gone, so repeat the rinse and wash.
