From Wikipedia "Isopropyl Alcohol"
Solvent
Isopropyl alcohol dissolves a wide range of non-polar compounds. It also evaporates quickly, leaves nearly zero oil traces, compared to ethanol, and is relatively non-toxic, compared to alternative solvents. Thus, it is used widely as a solvent and as a cleaning fluid, especially for dissolving oils. Together with ethanol, n-butanol, and methanol, it belongs to the group of alcohol solvents, about 6.4 million tonnes of which were utilized worldwide in 2011.[12]
Examples of this application include cleaning electronic devices such as contact pins (like those on ROM cartridges), magnetic tape and disk heads (such as those in audio and video tape recorders and floppy disk drives), the lenses of lasers in optical disc drives (e.g., CD, DVD) and removing thermal paste from heatsinks and IC packages (such as CPUs[13]). Isopropyl alcohol is used in keyboard, LCD and laptop cleaning
Perhaps you should've read Wikipedia before stating that it doesn't mention it as a cleaning agent.
That said, if you're going to use it. Use it in a weak solution, and moisten the cloth, so that it is damp, not dripping wet. You want to use the bare minimum.
