Why the right cleaner matters for electronics
Clean contacts, flux-free PCBs and grease-free mechanical parts keep projects working and reduce rework. We focus on cleaning solutions that remove flux, oils, adhesives and grime without damaging solder masks, plastics or connectors. Choose solvents and water-based degreasers suited to the task - not a one-size-fits-all spray - to protect components and speed up repair cycles.
Where South African makers and technicians see the biggest gains
Students and maker spaces save lab time by using fast-evaporating contact cleaners for switches and relays. Workshops and small production lines prefer low-residue circuit cleaners for batch rework. Field technicians need aerosol contact sprays that are safe for in-situ connector cleaning and leave no sticky residue.

Types of cleaners and practical uses
Below is a concise guide to common formulations and where they excel:
- Isopropyl alcohol (IPA) 90%+: general PCB cleaning, flux residue removal, safe for most plastics when used briefly.
- Low-residue electronic cleaners: designed to evaporate cleanly from contacts and solder joints.
- Non-chlorinated degreasers: good for removing oils from mechanical parts and enclosures.
- Aerosol contact cleaners: fast, convenient for switches, pots and connectors in the field.
Specification callouts to check before you buy
When selecting a product, confirm these key specs: evaporation rate, residue level, plastic compatibility, flash point and suitability for electronics. Below is a compact comparison table for typical product classes to guide purchases:
| Product Class | Evaporation | Residue | Best Use |
|---|---|---|---|
| IPA 99% | Fast | Low | Precision PCB cleaning |
| Low-residue spray | Very fast | Very low | Contacts, relays |
| Non-chlorinated degreaser | Moderate | Moderate | Greasy mechanical parts |

Quick application guides and safety notes
Work in a well-ventilated area, use lint-free wipes for wiping, and allow components to fully dry before powering. Avoid soaking connectors; instead, apply short bursts from a distance and work residue out with a soft brush. For classroom or lab settings, keep a stock of squeeze-bottles of IPA for supervised group use - they’re cheaper than aerosols and reduce waste.
