The belt dressing is causing the belts to slip. This is what is causing the noise. There is not enough tension on the belts. Not only is there not enough tension but the oil based dressing is harmful to the life of the belts. The sticky stuff is most likely dirt debris that the dressing picked up. It could also be a chemical reaction to the heat caused by the tension.
Overall. Belts are designed so that dressing is not needed. The purpose for dressings are to spruce up show cars that will not have much engine use, if any. The belts are usually wiped with the dressing and not sprayed on.
It is also not wise to spray any type of chemical on the engine as it can damage gaskets, rubber hoses, and possibly cause a fire.
