My hunting partner went on a late season Mulie hunt in NE Washington this past year. The temp. was in the 20's for the highs. He was having a problem with ice crystals forming along his arrows while they were in the quiver and when drawing the arrow over the rest, they would break off and make alot of noise. He was told to try unscented Pledge furniture polish. Spray it on a rag and wipe down your arrows, keeps the ice off, and helps when pulling arrows out of targets too. No scent to give you away, and one can lasts a long time. Bar soap typically has perfume in it, so I wouldn't reccommend it for hunting.
