When using Megs LT as a drying aid which has silicones I find it seems to reduce the effectiveness of my drying towels & makes washing them harder as the LT seems to 'clog up' the towels making them less effective next time they are used. I agree fundamentally that silicones are not necessarily bad but I'd rather look for a 'drying aid' QD that doesn't have them. I guess OID may fit the bill as I'm sure you are saying it's silicone free?
