Realizing that you have gone months without cleaning your carpet will fill you with dread, and your main concern here would be that you waited for too long and that there will be no way to bring your carpet back from the brink of its demise. There is a pretty good chance that you should call a cleaning service anyway, since even if your carpet looks worse for the wear, they can give you a more educated guess about whether or not there is any way to save it.
Since the stakes are so high here, you would understandably be nervous when a carpet cleaning service humble comes to your home. This can often lead to you fretting needlessly, and one thing that you might develop a concerning level of stress about would be the wetness of your rug. If you are worried that this is a sign that someone made a mistake, the truth of the situation is that it means the exact opposite. This is because of the fact that carpet cleaning necessitates the moistening of the rug, so there is nothing to be fearful of if this is what you notice.
That said, your carpet should not stay wet for long after steam cleaning. The maximum period of moistness that it can tolerate is a day, so the fact of the matter is that you need to dry it as quickly as you can. It should dry naturally within a twenty four hour window, but on the off chance that it doesn’t you should consider turning on some powerful fans and increasing the thermostat so that water can evaporate out of the rug.
