Remove blood stains

Blood stains are one of the most stubborn stains in the home. Whether from a small cut, an accident, or a nosebleed episode, blood leaves visible marks on almost any surface that become increasingly difficult to remove over time.

The most important principle is: the faster you act, the better the chances of removal without leaving any residue. Fresh blood stains are usually much easier to treat than dried ones. But there are also effective methods for older stains - from tried-and-tested home remedies to professional cleaning.

In this guide, we'll show you step by step how to remove blood stains from various surfaces. We also explain why some methods work and others don't - and when it makes sense to call in a professional cleaning service.

Removing blood stains – the most important immediate measures

Blood contains hemoglobin - an iron-containing protein that is responsible for transporting oxygen throughout the body. When it comes into contact with air, the iron in hemoglobin oxidizes and forms a solid bond with the material.

In addition, blood coagulates when exposed to heat - similar to egg whites when cooked. This is why you should never treat blood stains with warm or hot water.

Note: Always treat blood stains with cold water - never hot!

Why are blood stains so difficult to remove?

This chemical process is why dried blood stains turn a rusty brown color and become so stubborn. The heat causes the proteins in the blood to clot and ensures that the stain is permanently fixed in the tissue.

Yes, even dried blood stains can often be removed. Soak the stain in cold salt water for several hours. Enzyme cleaner or aspirin solution also help.
