Paper is very fragile when it is wet. Handle it carefully. In some cases it may be desirable to remove caked on mud and dirt. Dirt left by receding flood waters may be contaminated. Precau tions such as the use of rubber gloves should be taken. If items are still wet, agitating them in a bath of clear water will re move excess dirt. This treatment should never be attempted for images which are blurred, feathered, or faded as a result of flood damage.
