Deep-cleaning a pre-war walk-up studio on the Upper West Side

By the Manhattan Mint teamReviewed by the founderMay 12, 2026Service: Deep clean

The challenge

Pre-war buildings are beautiful, but they collect grime in ways modern apartments don't. This Upper West Side studio — roughly 450 square feet on the fourth floor of a walk-up — had cast-iron radiators that hadn't been cleaned behind in years, original moldings holding decades of dust, and window sills facing a busy avenue that turned black within a week of wiping.

Small spaces add their own problem: when every inch is used for storage, there's no such thing as an easy-to-reach surface. Under-bed storage, over-cabinet baskets, and a loft shelf all needed to be worked around without disturbing the client's system.

How we approached it

Radiators first, floors last

We clean pre-war apartments top-down and radiators-first, because radiator dust travels. A dedicated brush set and vacuum attachment gets behind and inside the fins — the single most-skipped area in NYC apartment cleaning. The full technique is in our pre-war cleaning guide.

Small-space choreography

In a studio, two cleaners get in each other's way. We sent one cleaner on a longer visit instead, working zone by zone so stored items went back exactly where they came from.

Avenue-facing window treatment

Sills and frames facing the avenue got a degreasing wipe rather than a dry dust — city window grime is oily soot, and dry dusting just moves it around.

The results

Radiators, moldings, and sills returned to their actual color — the client thought the radiators had been repainted.
The client moved to a recurring every-two-weeks plan with the same cleaner each visit.
