6 to 8 hours?
Does the VLM crowd bring down the average based on the reality that most HWE franchise goobs leave it wet for 24 hours?

The IICRC S100 Standard and Reference Guide for Professional Carpet Cleaning specifies: (Section 7.5, Drying) ...When cleaning carpet, it is highly recommended that drying occur within six to eight hours or less: however, drying time must not exceed 24 hours. Failure of the professional to implement drying procedures could result in a variety of after-cleaning problems. Often, occupant cooperation is needed to expedite drying.
With normal temperature and humidity coupled with use of your heating ventilation and air conditioning (HVAC) system, the carpet should be dry in much less than 24 hours. If it stays damp longer than that, the opportunity for microbial growth and associated odor arises.

You've seen the results of this discussion go all Ofer several times over the years. So why do you think it'll be any different this time?

In an area of very high humidity and widely stressed hvac systems it is likely to get one too wet on almost any day this month.
Always a battle.

Someone made a comment because I was saying my carpets dry pretty fast, the comment was made because Redding has very DRY (most of the time) HEAT and that it wasn't really all that big of a deal that I was getting carpets close to dry when I leave....I am using fans when I do this kinda cleaning.
What some don't realize is because Redding is a DRY HEAT a lot of folks still use Evap coolers or Swamp coolers and can stay pretty comfortable, but they can also make dry times go up by a pretty good amount.
After going back to Nashville and feeling what poeple deal with, I could see carpet taking a long time to dry, whole nother animal back east

There is no such thing as a standard dry time. Dry times vary by such factors as the relative temperature and humidity, the condition of the carpet being cleaned, the type of equipment being used, etc. For a moderately soiled carpet, using a basic prespray and rinse technique, at 40-60 % relative humidity at between 68-75 degrees f. using a average truckmount (4ml blower or equivalent) dry times should be aprox. 8-12 hours. May be expedited with dri-pods, snail fans or other. Heavily soiled carpets with the same environmental conditions may take up to 24 hours. People who claim dry times of 2 hours on residential carpet are full of shit.

With a relative humidity of what? 10-12% if that?

Average Humidity
In this table, the Daily number is the average of humidity readings taken every three hours throughout the day. Morning percentages are for 6 am and Afternoon measures are for 3 pm local standard time. At the one exception, Goodland, humidity data are for 8 am and 5 pm.
Average yearly relative humidity (%)
Daily Place Morning Afternoon
67 Concordia 81 51
61 Dodge City 77 43
62 Goodland 67 47
68 Kansas City 81 55
69 Topeka 83 53
66 Wichita 80 50
We don't get fast drying without a super effort, our humidity is too high.

Depends on if carpet is glued to concrete that sweats too. A little added moisture and it can stay wet for days without drying equipment.
A lot of homes here have been built 3 feet over water tables. Damp and moldy crawl spaces are common. Its big business fixing those.

The industry standard does not mean the industry average. The standard is what the consumer has a right to expect under normal circumstances.
I was on the body that wrote the section of the standard. Many hours of discussion and debate went into reaching a concensus that most of the group would agree to. The representatives of dry methods thought it shouyld say one hour or less so that their systems would be the only ones that met industry standards. Those whose companies did lots of commercial HWE brought up the situation of office buildings with no windows to open, and the HVAC turned off over the weekend and on evenings and asked for 24 hours.
Some who had concerns about bacteria or mold growth if the carpet was damp too long wanted to state 4 hours as the standard.
Yes, there are exceptions, but most of the time your customers has a right to expect the carpet to be dry in 6 to 8 hours. If a cleaner can not provide that on a regular basis, he is not meeting the industry standard.

So are you saying that cleaners in humid areas not use 12 flow at 700 psi and empty 8 to 1 Hydroforces in one home?

No but we do cool our shitters. Welp, we cut two windows for airlow that is.

I'm in the jungle of south Florida . I use 12 flow and it feels just damp to touch. I know that method is the same except for the amount of pre spray. The extraction is the same. I don't know what was done prior on the carpets or who was there before me. This does effect the final outcome. The jobs that I do year after year are always okay and I tell them to throw away the resolve and that helps. The new jobs are not the same because the owners are not always honest and will not say what has been done to the carpets. The amount of time the carpets were cleaned and O yea I use my Hoover to clean the carpets myself also effects the cleaning. And many other factors. I know that when I can clean a filthy white carpet and make it really white again that's my job. But when the carpets don't clean or dry like normal something is missing and I don't know what that is ?

Remember a few years back and the big push for 1 hour dry times?
Yeah.....I don't think too many remember. A few well known people on here were pushing it. I know that I use air movers/Dripods on most jobs. Along with their A/C's on full, most will dry in the 2-8 time slot, depending on thickness and density of the carpet. Now, carpet tiles are a different story. They are rubber backed and do not breath and allow airflow up through the fibers.
Now, having a Vortec/Aeroteck type TM will most likely decrease dry times substantially. My Pro 1200 can pull some great vac, but I'm also putting down a hi flow.
