Narrative:

We were returning from ZZZ. We had flown down on an IFR flight plan and had not encountered any icing despite being in the clouds. We did not obtain a full WX briefing prior to departing for our home airport. On the return flight; we began to accrete trace icing on the wings and windscreen. We were not able to descend any lower as we were at the minimum altitude in the area. Shortly; the ice began to engulf more of the windscreen. We flew the GPS approach into wadsworth; but despite breaking out; the ice did not sublimate from the windscreen. We had the defroster on high; but it was simply not putting out sufficient warmth to cause the ice to melt. We went missed; contacted akron; and received vectors for the ILS. We flew the ILS to minimums and landed by peering out the side window and the bottom corner of the front of the windscreen. We should have obtained a full WX briefing before leaving for home and verified that there were no reports of icing in the area. We should not have assumed that the WX on the way down would be the same on the way back. We also need to have the defroster examined to make sure that it does not need repairs.

Title: PA28 PLT ENCOUNTERS ICING CONDITIONS AND HAS DIFFICULTIES LNDG DUE TO ICE ON THE WINDSCREEN.

Narrative: WE WERE RETURNING FROM ZZZ. WE HAD FLOWN DOWN ON AN IFR FLT PLAN AND HAD NOT ENCOUNTERED ANY ICING DESPITE BEING IN THE CLOUDS. WE DID NOT OBTAIN A FULL WX BRIEFING PRIOR TO DEPARTING FOR OUR HOME ARPT. ON THE RETURN FLT; WE BEGAN TO ACCRETE TRACE ICING ON THE WINGS AND WINDSCREEN. WE WERE NOT ABLE TO DSND ANY LOWER AS WE WERE AT THE MINIMUM ALT IN THE AREA. SHORTLY; THE ICE BEGAN TO ENGULF MORE OF THE WINDSCREEN. WE FLEW THE GPS APCH INTO WADSWORTH; BUT DESPITE BREAKING OUT; THE ICE DID NOT SUBLIMATE FROM THE WINDSCREEN. WE HAD THE DEFROSTER ON HIGH; BUT IT WAS SIMPLY NOT PUTTING OUT SUFFICIENT WARMTH TO CAUSE THE ICE TO MELT. WE WENT MISSED; CONTACTED AKRON; AND RECEIVED VECTORS FOR THE ILS. WE FLEW THE ILS TO MINIMUMS AND LANDED BY PEERING OUT THE SIDE WINDOW AND THE BOTTOM CORNER OF THE FRONT OF THE WINDSCREEN. WE SHOULD HAVE OBTAINED A FULL WX BRIEFING BEFORE LEAVING FOR HOME AND VERIFIED THAT THERE WERE NO RPTS OF ICING IN THE AREA. WE SHOULD NOT HAVE ASSUMED THAT THE WX ON THE WAY DOWN WOULD BE THE SAME ON THE WAY BACK. WE ALSO NEED TO HAVE THE DEFROSTER EXAMINED TO MAKE SURE THAT IT DOES NOT NEED REPAIRS.
