If the integrated pop shield is made of gauze (metal mesh, e.g. with the V96), it is quite easy to clean. Simply immerse the removable gauze basket completely in soapy water or disinfectant liquid. Make sure that it is completely dry before you reinsert it.
If the integrated pop shield is made of foam material, it can be cleaned with soapy water, just like the wind shield. When it is completely dry, the pop shield can be carefully reinserted.
