Cyberpunk 2077 player sparks hygiene debate over blood-soaked cyberware retracting into V's arms

A Cyberpunk 2077 player has raised an uncomfortable question that many fans probably wish they'd never considered – what happens to all the blood and biological matter covering mantis blades and monowires after they retract back into V's body?

Reddit user No-Personality-61 brought the issue to the community's attention in early January 2026, expressing genuine concern about the implications of using these popular arm cyberware options.

"I can't stop thinking about our monowires and mantis blades getting covered in blood, guts, peepee, and poopoo, and then going back inside our bodies," — the player wrote, sparking a technical discussion that quickly put worried minds at ease.

The community responded with reassuring explanations about how cyberware actually functions. One user pointed out that these arm implants require complete limb replacement, with everything below the elbow becoming synthetic.

"The entire arm is removed when you get the blades/wires on," the commenter explained, suggesting a simple solution: "just get some car soap and water and get to scrubbin."

Another player provided more detailed technical context, noting that all cyberware components are hermetically sealed from the body in capsules made from inert materials. Any exposed components would trigger severe immune rejection, causing the arm to swell, inflame, and become unusable.

The discussion also highlighted the unique properties of monowire technology. As one participant explained, the weapon features "a monofilament wire with a cutting edge only a molecule wide" – making contamination physically impossible, especially after the intense movement during combat. Thermal variants of the monowire provide additional sterilization by burning away organic residue through high temperatures.

The original poster admitted discovering the full arm replacement detail only through the comments, joking that this revelation was "giving me cyber psychosis." However, the community was quick to provide perspective – in Night City's 2077 setting, the majority of V's body already consists of cyberware, making concerns about a couple of arms somewhat redundant at this stage.
