Is it safe to use vinegar and baking soda together for a narrow pre‑war galley kitchen sink cleanup (with marble counters and a garbage disposal)?

Short answer

⚠️Depends / use caution

It depends: It’s usually okay in small, open-drain uses with marble protected and good airflow, but it’s not ideal for cleaning power and can damage marble or trigger asthma in a poorly ventilated galley kitchen.

Why people ask this

In a tight pre‑war galley kitchen with windows closed for winter and poor ventilation, fizzing the disposal seems like an easy fix without strong cleaners. Renters also worry about marble etching around the sink and want to keep their security deposit while avoiding asthma flare‑ups.

When it might be safe

Small, open‑drain use where foam can expand freely (no caps, plugs, or bottles) and the disposal is off, with a towel or splash guard to contain splatter.
If the marble splash zone is fully covered and any vinegar mist or droplets are wiped up immediately to avoid etching.
When there’s some airflow (kitchen fan or door cracked) to limit aerosols that could irritate asthma.
On non‑stone sinks/counters (e.g., stainless, laminate) away from marble surfaces.

When it is not safe

Letting the reaction happen in a sealed or covered container—CO2 pressure can build and burst.
Using it near exposed marble or stone: acidic splashes can etch the marble around the sink, risking your deposit.
Doing this in a closed, poorly ventilated galley kitchen during winter if you’re prone to asthma—aerosols and odors can irritate airways.
If foaming causes backflow from the drain or the disposal splash guard, stop and don’t run the unit; repeated overflow or leaks warrant contacting building maintenance.

Possible risks

Marble etching or dull spots from vinegar splashes in the sink’s splash zone.
Foam pushing debris up from the disposal or drain, creating a mess and lingering odors.
Neutralization reduces cleaning power, leaving residue that may require extra rinsing/wiping.
Aerosolized acid/base mist in a narrow space can trigger coughing or mild asthma symptoms, especially with windows closed (~65°F).

Safer alternatives

Use a pH‑neutral, stone‑safe cleaner for the marble and a mild dish soap solution for the sink basin to protect finishes.
Mechanical disposal freshening: remove and clean the rubber splash guard, and wipe accessible surfaces rather than relying on foaming reactions.
For odor control, try enzyme‑based or disposal‑safe cleaners labeled fragrance‑free and stone‑safe; follow product guidance.
Improve airflow during any cleaning (stovetop hood or door cracked) and choose unscented products to reduce asthma irritation.

Bottom line

It can be done carefully, but it’s not the best method here: protect the marble, keep airflow, avoid sealed reactions, and consider stone‑safe, low‑odor alternatives for a narrow, poorly ventilated galley kitchen.
