After Cleaning Problems
Home ]

After the carpet is cleaned, the cleaning technician should place foiled-covered-cardboard or plastic squares under the legs of chairs. Heavier furniture like filing-cabinet should have a styrofoam or wooden block place under them so that the carpet can dry and to prevent staining problems. The example below shows how a chair with an iron tip can leave a rust stain.

A rust problem can be easily corrected with a special chemical. However, some of professional rust removers are extremely dangerous and can burn skin and etch glass. Make sure your cleaning technician neutralize such products and rinses them out.

Some carpets may turn brown after cleaning. One of two problems may exist: if the carpet was steamed cleaned and was really soiled, then deep embedded soil will migrate to the surface of the carpet during drying. See illustration below.

In most cases the cleaner likely did not prevacuum the carpet and could also have overwet it. If this is the case, then the problem is easily solved by recleaning. An example of a before and after recleaning is shown below.

If the problem is not solved by a simple recleaning, then the carpet may have a jute backing that got wet during cleaning. This problem is solvable by applying a 3% hydrogen peroxide to the brown yarn. In most of these cases, the cleaner likely got the carpet too wet.

Olefin is more likely to have this problem over other fibers. Steam cleaning will be the method of cleaning more likely to have this problem. Berber is the style of carpet more likely to suffer from wicking. In addition, improper or excessive usage of Powder Carpet Deodorizers can be one the many culprits to lead to this problem.

Some tufted carpets will from ripples after they are clean due to a temporary contrast in the way the backings materials may expand. If this happens to you, do not panic, your carpet will go back to it normal state upon drying. Try not walking on it while it is in this condition. An example of this problem is below.wpe8.jpg (46356 bytes)

Some household chemicals such as Acne mediations like Oxy Plus can cause a color loss problems that show up after a carpet is cleaned. Residues of these products often get reactivated with the moisture of cleaning and upon drying the first evidence that problem existed before the carpet was cleaned. The photograph below is an example of how Acne medication residue from a teenagers hand left a spot in the carpet after drying from cleaning.

Color loss next the walls may also take place after cleaning. If it in the hallway and under doors, then it is likely due to problem called fume-fading, (click on the text to see more about this topic). If the problem takes place next to a wall that boarders the outside then chemical residues from pesticides would be the likely cause. 

Some woven carpets can shrink if their backings contain one contain one or more natural and/or cellulose fibers. In nearly all cases, the responsibility goes to the cleaner, because the S001 Cleaning standard said that cleaning technicians should check fibers both on the face of the carpet and the back. In some cases the carpet can be restretch; Axminster carpet can only be restretched in its length. However, in many cases the carpet is ruined.
Woven carpets look like this on their backside.
