We propose a method for detecting an ambient density of heavy, electrically-charged particles. Such particles would impact the Earth, lose energy in terrestrial matter, and become trapped. We study the accumulation of these rare particles in multiple target materials that provide large exposure, such as water and geological rocks. We discuss strategies for concentrating the particles by centrifugation or gravitational settling, along with particle identification using mass spectrometry. This method enables the discovery of charged relics with masses $$1-10^{12}\,{\rm TeV}$$ comprising a tiny fraction of the local dark matter density, reaching down to $$f_X\sim 10^{-20}$$ at the lowest masses. A pathfinder experiment using only a liter of water and one centrifuge (or $$\sim \text{m}^3$$ and no centrifuge) operating for a month can already reach $$f_X\sim 10^{-10}$$ and probe new parameter space.
