What is the best soap to wash hands with prior to handling contact lenses?

i have read that soap with fragrence and other additives make lenses wear out prematurelyWhat is the best soap to wash hands with prior to handling contact lenses?
It is recommended that you use an additive free bar soap, such as Ivory (99.4% pure, per advertisement). You want to avoid soaps with antibacterials, lotions or perfumes. Avoid liquid soap. The reason to avoid these is not due to damage to the contact lenses but in order to prevent eye infections and irritation. After washing, dry your hands completely. (I'm an R.N.)
