Drying a Rug in Tampa Air
Drying is the hard part of rug cleaning in Tampa, and the reason is one number: the longest unbroken run of days at or above 75% relative humidity in the five-year record is 107 days. For roughly 15 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 107 days at a stretch Tampa 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 rug that has been rolled up in storage
A rolled rug has no air movement through it at all, and in a garage or attic here it spends the warm season at 60 days over ninety degrees with the air outside it above the mold threshold 211 days a year.
Unroll it outdoors if you can, look at the back rather than the front, and photograph it before moving it any further — a rolled rug that has bloomed is a different job from a dirty one, and we would rather know which before collection.
Rain, and the trip to the workshop
150 days a year here see measurable rain, totalling 53.4 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
On the slab floors that dominate St. Petersburg, Clearwater and Palm Harbor, 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.
St. Petersburg, Clearwater and Westchase bring masonry walls into it, and the strip of floor along a masonry exterior wall stays colder than the rest of the room.
Moisture collects at the coldest surface, so the edge of a rug against that wall is the part that goes musty first and the part worth checking a month after it comes back.
Housing on this route starts in the 1920s, 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.
