Preserving your clothing is more than just storing them in the best acid-free boxes or muslin garment bags.  The clothing needs to be clean, and in good condition.  Keeping clothing clean throughout its lifetime of use will help, whether you store it for a season or for the next generation.  

Overloading the Washer
This common mistake leads to poor cleaning performance, more wrinkles, and excessive wear on garments. Dirt and soil from some garments can become redeposited in others, dulling vibrant colors and giving a dingy look to whites.

Poorly Sorted Loads
This can cause problems with dyes bleeding onto other garments.

Too Low Water Temperature
Detergents are more active in higher temperatures and will get your clothes cleaner.

Not Sorting Drying Loads and Overloading the Dryer
It takes longer to dry and lightweight or delicate fabrics get over-dried, resulting in permanent wrinkles in heat sensitive fabrics.

Or you can let the professionals do your laundry.
