It's not about it being better dissolving stuff, it's about leaving less water behind which may cause BAD THINGS (tm) to happen when power is applied. As to crazing plastic, either way you are applying IPA. If it's going to craze the plastic it's going to happen with either concentration. 90% might cause more crazing for a given exposure but it shouldn't be a lot more. -- Clark Martin Redwood City, CA, USA Macintosh / Internet Consulting "I'm a designated driver on the Information Super Highway" --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to Low End Mac's G-Books list, a group for those using G3 iBooks and PowerBooks (we run a separate list for G4 'Books).
