chill out... dont freak... its easy... IF you have a nice exacto. just take the tip of the exacto and pry out the very tip of one of the clips that holds the shield in place, but make sure to hold onto the other side of the clip otherwise it will fly off. clean with your choice of liquid, relube, and place the metal shield back on. Now put the clip back in place and use the exacto tip to nudge it back into place. becareful not to cut yourself
take it easy and you wont even scratch the shields.
