1. Sort ties before washing, especially lights from darks.  Separate red silks to wash separately. 

2. Wash neckties before taking them apart.  Use a dye fixative with mild detergent and finish with a bit of liquid fabric softener.   Line dry or in a dryer on delicate setting.

3. When taking ties apart, don't remove the lining from the tips UNLESS you plan to use all the tie fabric.  The tips make perfect "prairie point" embellishments.
