The truly disorienting thing about carpet cleaning is that sometimes when you think you have done it really well you might realize that the exact opposite happens to be true. A big part of the reason why that is the case has to do with the fact that a lot of newbies that are trying to clean their carpets think that they have performed the task well, but they have most likely not penetrated beyond the outermost surface at any given point in time.
If you really want to do area rug cleaning effectively in some way, shape or form, suffice it to say that you need to get the carpet cleaning solution deep down into the carpet. Not doing so can make the exterior fibers seem clean but just underneath them there would be a veritable civilization of creepy crawlies as well as all manner of mold and other forms of microorganisms. In order to get press the solution further down in your carpet, you need to first get a brush that has the stiffest bristles you have ever seen.
The next thing to do is to brush the solution in with an appropriate amount of force. It would also be really helpful if you considered brush against the natural placement of the fibers. This will lift them up, thereby enabling you to reach parts of the carpet that would have otherwise remained hidden for the most part. Make sure that you brush against every inch of the carpet otherwise your cleaning efforts would all go in vain and your carpet would start to look dirty and worn out again in no time.
