Carpet Fluid is a liquid found emanating from certain sections of the carpet of The Halls, or dripping down from the vertical shafts of The Basement, running along the black pipes of the Cogwell Matrices.

The liquid itself is wine-colored in appearance with a deep red hue, and this similarity to wine is also evident in its low viscosity and density. Disturbingly, some reports exist on its taste, with records stating that it has a "metallic tang". The creator of these reports was anonymous and so this cannot be confirmed and will not be tested.1

Carpet Fluid should not be consumed under any circumstances or contacted without protection due to its extremely poisonous qualities. Not unlike mercury, the fluid can easily be absorbed by the skin and enter the bloodstream even if not directly consumed orally. These qualities are likely caused by a number of heavy metals found in the composition of the fluid, identified by their response to a variety of chemical compounds. The reaction found between acidic instances of Carpet Fluid and materials such as gold is comparable to hydrochloric or sulfuric acid.

In its normal state, Carpet Fluid is non-acidic but an acidic form, found within the pipes of Cogwell Matrices, does exist. This acidic form can cause dire chemical burns2 if not immediately washed away with running water3 immediately upon exposure.


Carpet Fluid is poisonous and usually avoided outright by wanderers. However, Carpet Fluid has been used as a crude alternative to oil and is utilized by more industrious communities across liminal space.

It has been noted that mechanically inclined wanderers often use acidic Carpet Fluid to remove rust from tools and weapons. While this is effective, it is also ill-advised to do so without proper preparation and protection.


Carpet Fluid has been reported within the Backrooms as long as there have been people in liminal space to record it. There is no specified date for the first discovery of the liquid.
