The Pesky Science of the Coffee Stain

Apart from staying late at work, coffee stains may just be the bane of the average person’s 9-5 job. These stains are prolific, noticeable, and take more than a decent scrub to get out. Although we despise coffee stains, through science we can learn both how to get ride of them once and for all as well as how to appreciate them for the nuisances that they are. If you just can’t stand to sit next to a coffee stain-ridden rug for another minute, call a NYC-based industrial cleaning service. In the meantime, let’s learn about how your morning wake-me-up got lodged into the carpet fibers below your feet.

What we need to know first is that not all liquids dry in the same way. Sure they all will most likely leave a mark on the carpet, but coffee in particular is made up of thousands of spherical particles, which due to their size and shape seep into carpets differently than other liquids.

During the drying process the coffee drops begin to evaporate quicker on the drop’s thinner edges. In order to make up for what the drop has lost, the coffee spill starts to shift mass from the center to the sides where the coffee has begun to evaporate. When the coffee begins to replenish what it’s lost from its thinner sides, it also carries micro-drops that have already dried with it. After all the water have evaporated, it’s the solids that were carried out to the edges that are most prominent when the spill dries. That’s why the perimeter of the spill is always darker than the center.

The super dense edges of coffee stains make them especially difficult to remove. Save your time and energy for your work, and call the business carpet cleaning professionals at Blue Chip based in NYC.
