1) How to maintain your carpet, to prevent it from getting dirty
Vacuum at least once a week, with the brush extended to the maximum, more difficult to pass, but more effective. This straightens hair &; removing dust as it goes. If your rug is shaggy, you can shaking it out to dust it.
2) Protect your carpet traces furniture
The traces of furniture are often indelible, because over time the hairs or even the weft of the carpet are completely crushed. To remedy this, insert a small piece of carpet cut to the dimensions of the foot of the furniture. To remove these traces, use a steam iron set to the cotton setting, place it above the crushed hairs without pressing and brush the hairs as you go to straighten them.
3) Never clean an isolated stain
Your carpet is not necessarily clean and any cleaning action on a small surface will necessarily leave a halo, or even a "stain" of clean on the dirty! Absolutely avoid. If you drop something solid or liquid, pick it up immediately with 2 spoons and blot with paper towel. To clean a carpet, you have to clean the entire surface!
Please note that all the solutions recommended below must be tested on a small piece before launching, because wool, silk, cotton or synthetics do not react at all in the same way to products and colors may run.
