Q tips? Negative.
Prior to buffing, take a 1" soft bristle brush and cut the bristles down to about 1/4" with scissors.
Use degreaser and work the brush around the emblem, and rinse with water as you go.
I use the same method on rubber trim. It really cleans it up, and helps the masking tape adhere.
After buffing, use spray wax or quick detailer on the emblem and work around it with the brush again. Then use a microfiber towel, and wipe clean.
Make sure all residue is removed from around the emblem.
( I do the same to the door jambs and body lines that retain wax. )
Then do your final wash. The emblems will be spotless every time.
