- Fill the tub with water. A large tub will allow you to soak multiple shots of line at the same time.
- Dump about 1/2 box of baking soda into the water.
- Pour the amount of liquid laundry detergent needed to wash a small load of clothes into the tub. The inside of the cap will be graduated, so measure out just enough to reach the lowest line.
- Add one or two cap-fulls of household chlorine bleach to the water.
- Stir the water gently until the baking soda dissolves.
- Place the lines in the tub and let them soak. Check the condition and color of the water after three or four hours. If is discolored or cloudy, or if dirt has fallen to the bottom of the tub, dump the tub, refill, add fresh ingredients, and continue soaking the lines.
- Continue checking, and if necessary, replacing the water and ingredients until the lines no longer release any trapped dirt.
- Rinse the lines in clean water to remove any traces of detergent or bleach.
- Dry the lines in a warm shady place with good air circulation. After they have dried completely, reinstall them on your vessel.
Things You Will Need
- Large plastic tub (12 to 15 gallons is an ideal size)
- Baking soda
- Liquid laundry detergent
- Household chlorine bleach
- The trick with this procedure is patience. Don't expect severely stained or discolored lines to come clean after a single soaking.
