Bob , with rubbing alcohol, it is the ideal cleaner for your audio components, ( faceplates, cases , audio racks, cables ,ect. i recommended this to all my customers and they seemed to agree. the oil content is so minute , you will never know it there. as for contacts it cleans perfectly, helping to prevent oxidation, commonlly found in the jacks and back of unit conectors, Rubbing alcohol never held any dust , nor attracts it. what's wrong maybe it too cheap? ever thought what is in "Kontact or Ultraconnect"
I advise people in this thread to try it with a white terry towel ( wash rag ) and tell me what you think. Bob you may have some knowlege in industrial aplication in the mater, but I have knowlege in both. In mater of fact Levinson and a few others recommend this and uses it themselves! call Sara Reed of madrigal.
