Yes. Isopropyl alcohol (IPA), particularly high-purity 99% IPA, is widely used to clean printed circuit boards (PCBs) and electronic components. It effectively removes flux residues, oils, grease, fingerprints, and other contaminants while evaporating quickly and leaving minimal residue. For the best results, use IPA with a lint-free, cleanroom swab or wipe to avoid introducing fibres or particles. Always ensure the equipment is powered off and completely dry before reconnecting or powering it on.

Foam swabs generally produce the least lint because they are made from open-cell polyurethane foam with no loose fibres to shed during use. They are ideal for cleaning delicate surfaces, optical components, electronics, and other contamination-sensitive applications. Polyester swabs also offer excellent low-lint performance and are well suited for cleanroom environments where durability and abrasion resistance are required. Choosing the right swab depends on your application, but foam swabs are typically the best choice when minimising lint is the highest priority.
