Necktie Storage and Care Tips
Ties are the most perishable item in a man's wardrobe, and as such they should be cared for appropriately.
With proper care, your neckties can last almost forever. And if you've chosen them with a proper eye toward proportion, there's no reason you can't wear them at least as long as that.
Here are a few general rules for taking care of your neckties:
General
The best way to keep your ties in presentable condition is to have enough of them so you're not wearing them out too fast.  This is also a less expensive way to give depth to your wardrobe.  As a rule of thumb you should have three or four ties that go with each suit or sport outfit.  Keep the ties hung with the suit they go with and rotate the ties through with each wearing of that outfit. Give your ties at least two or three days rest before wearing them again to allow wrinkles to hang out.

Un-tying
Care should be taken when un-tying ties in order to maintain appearance and promote longevity.
No matter how convenient it seems to slip the small end out of the knot, remember that you are significantly decreasing the longevity of the tie by using this method; always unknot your ties when taking it off by reversing the knot itself (this reversal of steps will untwist the fibers of the material and lining and will help alleviate light creases) , never slip it over your head or unravel by pulling on the small end.
Always un-knot your ties when you're not wearing them, leaving them knotted will cause permanent creasing.
Storage

Tie-hangers that hold a single tie like you see in many shops are a good way to hang your ties with the outfit they go with (available at easily affordable prices).

Don't leave the knots in as they will permanently crease the fabric

Remember, however you hang you ties, to move them occasionally to prevent unnecessary and unsightly creasing.

Hang your ties at night after wearing, regardless of material.

Silk Ties are suited to hanging storage

Knitted or crocheted ties should not be hung but laid flat or rolled up instead and then placed in a drawer.

When traveling, utilize one of these methods to ensure your necktie arrives in good condition.

When packing, fold the tie gently into four and slip it in the inside pocket of your suit jacket or alternatively, roll your necktie and place it into a small box and tuck those boxes safely in the corners of your luggage.

Upon arrival, hang the necktie on the washroom door before you shower, the steam will do wonders for relaxing the fabric.

Crease Removal

Rolling the tie up from the narrow end first and leaving it rolled for a day or two will remove most wrinkles.

To do this, put the two ends of the tie together and roll the tie around your finger like a belt. Slip it off your finger and leave it rolled up overnight. Also try not to make the knots too tight.

Re-shaping/Conditioning

Because the favorite ties get the most use, it is highly recommended that you purchase a small hand steamer and gently steam away the wrinkles that usually form around the fabric where the knot is made.
This should be done at least every two months - and that is assuming that the necktie is worn about eight times in that period taking care of your tie collection will provide many wonderful years of elegance for you to enjoy these prized possessions.

Cleaning Ties
First thing to understand is that most cleaners can't clean a tie. If the methods mentioned here don't work, retire the tie. Most experts agree that one ought not to send a tie out to be dry-cleaned. While dry-cleaners may be able to remove spots, once they press the tie, they will compress the lining and dull the luster of the silk. Pressing ties is not recommended as the overall appearance will be diminished as the ?roll' at each edge becomes a ?crease'.
Water Spots

Let the spot dry, then rub the small end of the tie or a separate piece of the same fabric or material on the spot or very gently scraping the surface with a fingernail.

Other Stains

For simple stains simply dip a clean cloth napkin in a little seltzer or club soda and then dab away what you can.

For tougher stains apply steam from an iron with out touching the iron to the material or hold the tie over a boiling kettle. Then use a dry or powdered spot remover following instructions on the container.

More serious stains will often respond to a spot remover such as carbon tetrachloride

For anything greasy, sprinkle a little talcum powder on the spot as soon as possible and allow it to absorb what it can. After a few hours, brush off the remaining residue with a clean soft cloth

Material Specific Tips

NATURAL SILK

- Continuous exposure to sunlight leads to yellowing of white silk and decreases the silks strength.

- Remember that silk fabrics get damaged by the sweat.

- Make sure to iron at low temperature without steam and always on the back side of the necktie!

POLYESTER SILK

- Make sure to store these ties in a dry storage place as polyester silk is especially sensitive to dampness and mould may irreparably damage the polyester silk necktie.

- It is also prone to insect attacks by a silvery insect that is similar to the clothes-moths but without wings. Put a suitable insecticide into your wardrobe.

- You can iron polyester silk ties at a little higher temperature than silk, but without steam. Don't forget that very high temperature may melt the polyester fibers. Of course always iron the back side of the necktie!
WOOL

- The tie made of wool is the only tie that could be dry-cleaned if necessary. Manual washing isn't recommended because wool shortens at washing.

- Don't forget that the moths love wool, that's why, put a suitable insecticide into your wardrobe.

- Ironing is to be done at the temperature recommended to the wool. You may use steam. Of course as always, iron the back side of the necktie!
