Vomit on Granite
Vomit contains stomach acid and proteins. Treat with enzyme cleaner — and act fast to prevent fiber damage.
checklistTreatment Steps
Critical Warning
Granite is much more durable than marble but still porous — unsealed granite absorbs oil, wine, and coffee within minutes. A well-sealed countertop resists stains for hours, but you should still blot spills fast. Avoid vinegar, lemon juice, bleach, and ammonia — repeated use breaks down the sealant and eventually etches the stone. Skip abrasive pads that can scratch the polished finish.
helpFrequently Asked Questions
How quickly should I treat a vomit stain on granite?
expand_more
Vomit contains stomach acid and proteins. Treat with enzyme cleaner — and act fast to prevent fiber damage. As a rule, fresh stains lift much more easily than dried ones — try to treat within the first hour for the best results.
Will hot water set vomit stains on granite?
expand_more
Yes. Hot water permanently sets protein-based stains like vomit. Always start with cold or lukewarm water.
Can I machine-wash granite after treating a vomit stain?
expand_more
Yes — once the stain is fully lifted, machine wash according to the care label. Never run granite through the dryer if the stain is still visible: heat will set it permanently. Air dry and inspect the area first.
What if the vomit stain comes back after drying?
expand_more
Stains that reappear are usually residue or oil that wicked back up as the fabric dried. Repeat the treatment from step one, and avoid heat-drying until the stain is completely gone. Multiple gentle passes work better than one aggressive treatment.
Can I use bleach to remove vomit from granite?
expand_more
Only if the care label specifically allows it — and never on coloured granite. Bleach can weaken fibres and create permanent white patches. Oxygen bleach (non-chlorine) is a gentler option when bleaching is needed.
