Drying a Rug in Savannah Air
Drying is the hard part of rug cleaning in Savannah, and the reason is one number: the longest unbroken run of days at or above 75% relative humidity in the five-year record is 67 days. For roughly 10 weeks together, the air in this metro will not take much water off a rug, which is why a wash that starts and finishes in your living room cannot work here.

Why it cannot dry where it lies
A rug washed in the room it lives in has to give its water back to that room's air, and for 67 days at a stretch Savannah air is already at or above 75%.
Air that damp takes water out of a rug slowly at best, which is the whole problem with in-home wand cleaning here: the pile dries, the foundation does not, and the rug smells fine for a few weeks and then does not.
The pile is not the part that matters
Wool will carry close to a third of its own weight in water without feeling wet, and on the 162 days a year that reach 80% relative humidity it is doing exactly that.
So a rug that feels dry to the hand can have a loaded foundation, which is why drying is taken to moisture readings rather than to touch, and why the back of a rug tells you more than the front.
Rain, and the trip to the workshop
141 days a year here see measurable rain, totalling 54.3 inches, so a rug leaving the house is wrapped for the weather rather than for the look of it.
It is also why we would rather collect a wet rug than have it wait: a rug that is already damp when it is rolled is in the worst possible condition for sitting still.
The floor the rug goes back onto
Isle of Hope, Skidaway Island and Tybee Island sit close to water, and a rug from a waterside room starts wetter than the same rug five miles inland.
That shows up as odor returning rather than as visible soil, because the source is moisture in the structure rather than dirt in the pile.
On the slab floors that dominate Whitemarsh Island, Richmond Hill and Pooler, the rug is only half the problem.
A slab in contact with ground moisture will re-wet the underside of a clean rug, so a pad that lets air move beneath it does more for the smell staying gone than anything that happens during the wash.
Housing on this route starts in the 1870s, so a fair number of these rugs are drying onto floors that are older than any vapor barrier — a detail worth settling before the rug comes back.
