Isopropyl Alcohol (IPA) is a high-purity 99.9% isopropanol in a 400ml bottle. It is a trusted cleaner for electronics, PCBs, laptops, mobiles and lenses. It evaporates quickly and leaves no residue, so it is safe for delicate components. For electronics and PCBs: Apply with a soft brush or lint-free cloth to remove flux, dust and grime from circuit boards, connectors and ports. Let it dry completely before powering on. For laptops and mobiles: Dampen a microfibre cloth lightly and wipe screens, keyboards and body panels. Do not spray directly onto the device. For thermal paste: Use a cotton swab or cloth with IPA to remove old thermal paste from CPUs and GPUs before applying fresh paste. For lenses and optics: Clean camera lenses, eyeglasses and optical surfaces with a few drops on a lens tissue. For 3D printing: Wash resin prints in IPA to remove uncured resin before curing.
