Carpet Water Stains

Carpet Water Stains

There can be many things that contribute to carpet water stains.

Spills, snow and water tracked in, rain through an open window, pipes bursting, leaky radiators, floods and even over wetting by do-it-yourself carpet cleaners can wet out the backing yarns of carpeting.

Followed by slow drying, this wetting will allow dye-like materials to dissolve out of the backing yarns and “wick” to the face of the carpeting.

The brown discoloration which forms is usually referred to as a water stain.

After a water stain has developed, it may be impossible for even a professional rug cleaner to remove it.

Gradual and uniform soiling on the face yarns may cause the stain to go unnoticed until the carpeting is thoroughly cleaned.

Once the dirt is removed, the dye-like stains becomes quite apparent. However, water is essential to professional rug cleaning.

The professional cleaner knows the proper amount and the conditions under which water can be used on carpeting. For example, in a modern rug cleaning plant where controlled drying temperatures are possible, it is a safe and normal procedure to use hundreds of gallons of water on a single rug.

Professionals adjust the amount of cleaning solution, depending on the type of carpet, to avoid water stain problems.

Only surface yarns are wet out, which will result in maximum on-location cleaning and prevent water stains from occurring.

Carpet Dye Bleeding

Carpet Dye Bleeding

Dye bleeding or color bleeding is one of the most common problems that a consumer faces while cleaning a carpet. This happens when dye materials used in the carpet become wet and start to blend with each other. There are various reasons for color bleeding such as: Usage of Non-colorfast Dye – The dyeing material that has been used on the yarns may not be colorfast.

If there is no suggestion made on the labeling then it is important to do a dye check before cleaning the carpet. Excessive Dye – There are instances when excessive dye has been used or additional dye has been used on a carpet after weaving in order to make it look more bright and colorful or give a certain look. Many a times ink is used as well that are quite different in nature and are bound to bleed. Using a wet towel in one of the corners may show whether or not excessive dye has been used. High Heat and Alkaline Exposure – Exposure to high heat and alkaline products while cleaning may lead to bleeding of color form the carpet. Pet Stains – improper cleaning of pet urine may result in bleeding dye though the urine is of acidic nature it can convert to alkali if left un-cleaned. In most cases, dye bleeding can be prevented or controlled with the usage of appropriate kind of dye stabilizer and shampoo. However it is important to check the amount of heat and humidity in the air before cleaning a carpet.

Carpet Colour Changes

Carpet Colour Changes

There are various factors one must check before buying a carpet for their home.

If not scrutinised properly before buying, there are possibilities that a carpet may need to be replaced due to discolouration, or colour change, way before the life of the material is over.

The factors behind the colour change of a carpet are usually created by environmental reasons rather than manmade or controllable circumstances.

There are two major factors contributing towards carpet colour change.

  1. Fume fading: Occurs due to change in the dye chemicals because of environmental factors such as air pollution, excessive amount of nitrogen oxides and sulphur combined with over exposure to sun, heat, acidic materials in the carpet, and high humidity. The change in colour in such cases is usually gradual and starts at the tufts and progresses towards the backing. Some common examples are turning of blue to pink, brown to red and green to yellow.
  2. Ozone fading: Usually caused by ozone exposure in the surrounding environment combined with sun exposure and excessive heat. Ozone fading is more common in the urban area where the amount of ozone in the air is increased because of electrical motors, lightning storms and fluorescent lights and the reaction between the polluted air and light. Ozone fading usually results in faded and lightened colour and many times a complete change of colour similar to fume fading.

Before purchasing a carpet, it is important to check the kind of dye material that has been used for colouration.

There are instances wherein an indicator dye is used for colouring of carpet which is highly sensitive to alkaline products and may change colour if washed with ammonia or alkaline detergents.

This is called the ‘Indicator Effect’ and can be reversed with the usage of acidic products.

There are dyes that are sensitive to acid and changes colour if exposed to acidic cleaners and vinegar. In such cases ammonia can be used to restore colour.

It is important to keep in mind that the ageing process also contributes to the change in colour and it is important to take the help of professional carpet cleaners who are well equipped to handle such situations.

Removing Brown Carpet Stains

Cellulosic browning of carpet often becomes an eyesore and spoils the interior and the overall look of a room.

The browning usually happens to carpets that are made of natural filament fibers, or in simple words threads that are cellulosic such as cotton, linen and jute.

Carpet made out of such natural material is always healthier, ecologically beneficial, and requires lot of care.

The main reason behind cellulosic browning is caused by over-wetting of the carpet. The resulting slow drying process can make a natural sugar substance called lignin, which is present in the material, to get dissolved and ultimately rise to the surface of the carpet.

This occurrence can also be seen in news papers if they are left outside for a very long time.

In order to prevent cellulosic browning, one must determine the material that has been used for making the carpet by doing a test. Usually carpets have a jute backing or cotton base.

After the material has been determined it is important to remember that the cleaning products used should be of an acid or neutral base. If an alkaline product is used for cleaning then it should immediately be rinsed off with an acidic side cleaner.

One must keep in mind that there are other factors such as humidity, the water used for cleaning and expertise that can affect the carpet.

It is always a good idea to get a professional carpet cleaner to make sure that inconvenience such as cellulosic browning does not occur. An even a better idea is to get the brown carpet stains removed by a professional rather than trying home remedies.
