Aerol Contact & Component Cleaner Spray, Grade 8003 is a pressurized aerosol spray cleaner for cleaning, maintaining and servicing electrical and electronic components, switches and circuit boards. It does not contain any lubricants. It is composed of a special cleaning fluid exhibiting low surface tension, high solvency, relatively rapid evaporation characteristics and deep penetrating properties. It does not attack metals and common plastics. However, certain delicate plastics and PCB protective coatings may be affected by contact. Being a pressurized, cold cleaning solvent it readily dissolves contaminants such as dust, dirt, oils, greases, waxes, flux, carbon deposits etc and flushes them away. Applications: It is commonly used to clean electronic components and circuit boards of Television, Radio and Audio Equipment, Computers, Phones, Fax machines, telecom equipment, electronic household, Industrial, office and medical equipment etc. Also used to clean commutators, coils, relays, battery terminals, bus bars etc Method of use: Attach the extension tube to the nozzle. Spray directly on the desired surface. Dirt and grime removal shall take place immediately. For stubborn dirt, use a hard brush to clean and spray again. Blackened surfaces may not be cleaned due to permanent tarnish. As certain coatings on PCB may not be compatible with this cleaner, a compatibility test must be done on a small area of the PCB to ensure acceptability, prior to full-scale use.
