A conveyor belt includes a cover layer defining a load carrying surface, a pulley engaging layer disposed parallel to the cover layer, and a carcass containing a reinforcement layer, where the carcass disposed between the cover layer and the pulley engaging layer. The cover layer is formed by curing an admixture containing at least a cross-linkable functionalized polyethylene and polyethylene polyolefin. According to the disclosure, the cured admixture is effectively maintained within the cover layer during use of the conveyor belt. In some cases, the load carrying surface maintains a wet clay cleanability value of greater than 3, or even a wet clay cleanability value of greater than 4.4. The cross-linkable functionalized polyethylene may be a cross-linkable oxidized polyethylene. In some aspects, the cross-linkable functionalized polyethylene does not form a polyethylene film upon the load carrying surface.
