The Weber enamel gas barbecue cleaning kit is compatible with the Spirit E-425 GBS. This barbecue model is part of the Spirit E-425 range, for which Weber accessories and cleaning utensils are designed, including those suitable for enamel grills.

The enamel set should be the right one according to the Weber homepage. As far as I know, the E-310 GBS should have enamelled cast iron grates.

The manufacturer specifies use only for enamel gas grills.
