Over time, your flag will wear and may tear as well. Some say to replace the flag as soon as it shows signs of damage, but you can make small, generally unoticeable repairs to the flag as long as it looks undamaged. Try not to expose your flag to unfavorable weather (extreme winds, heavy rain, snow). Do Not roll up, fold, or otherwise crease a wet flag; allow it to dry laid out flat. Warm water and soap is acceptable to use, as long as the flag doesn't sit in the water any longer than neccessary for washing. Colors can run if the flag is left in the water too long.
Nylon and Cotton flags are generally expected to last around 3 months (90 days). Flags should only be flown during daylight hours, unless flag is lighted. Studies have shown that the lifespan of flags flown 24 hours a day is approximately one fourth of what is expected.
Dry cleaning is recommended for Indoor Flags. In the months of June and July, some dry cleaners offer free flag cleaning services, so be sure to check your area.
Although there is no official Flag Code for determining the correct flag size for your flagpole height, for aesthetic reasons, it is important to choose the a flag that is proportionate. The rule of thumb is that the length of the flag should be one-fourth or one-third the height of the flagpole. Traditionally, most people follow the one-fourth rule when choosing a flag size for their flagpole.
If you are displaying two flags on a flagpole, choose a size smaller than the recommended flag size for your flagpole height. For example, if you should display a 4' x 6' flag on your flagpole, fly two 3' x 5' flags instead. If you would like the higher flag to be larger, use a 3' x 5' flag on top and a 2' x 3' flag at the bottom.
