Blood Stains
If a blood stain appears on your carpet, try to remove as much of the stain as possible by using a paper towel. Then mix one tablespoon of household ammonia with half a cup of water and apply directly, just make sure that the backing of the carpet does not get wet. Use a white paper towel again to remove the access moisture.
You can then mix dish washing detergent with water and apply a small quantity on the spot by blotting with a white paper towel until the spot is removed. Finally, use tap water to rinse the carpet and remove the excess moisture with a paper towel.
If the stain still remains, use 3% hydrogen peroxide and leave it for one hour. Apply paper towels to remove excess moisture.

Candle Wax
To remove a candle wax stain, put brown paper or a cloth over the spot and iron, but make sure that the iron is set to ‘warm’. Most of the wax should be absorbed by the paper or cloth and you can then apply alcohol on a clean cloth and remove any traces by gently rubbing the area.

Chewing Gum
The most effective method for removing a chewing gum from your carpet is to freeze the gum with ice cubes and then remove it by using a knife handle and a vacuum.

Coffee
The first thing you need to do if you spill coffee over your carpet is to try to remove as much of the stain as possible by blotting with a white paper towel. Then, apply white vinegar mixed with water by using a spray bottle and blot again with white paper towel to remove moisture. Next, mix dish washing detergent with water and apply the detergent solution to the spot. Use a white paper towel to remove the excess moisture again. You can then rinse with water and apply a pad of paper towels, but allow some time for the moisture to be absorbed.
