This isn't for the faint of heart, however. I have a strong stomach, but this one made me gag. So this might be a job you sweettalk/bribe/force someone else to do for you. ;-)
Step 1: Gather tools
- Pliers or other pinchy thing
- Long screwdriver or other poky thing
- Bucket O' Happiness
- Towels or other absorbant things
- A strong stomach
- An air freshener
- Music/podcasts to take your mind off things
Step 2: Disconnect the pipes
Step 3: The fun bit
Step 4: Cleaning out the other pipes
Oh. No, that's okay. I'll wait here. I should have told you we weren't throwing them away forever. It sure looked like we were.
Alrighty then, take them outside (so you don't start a horrible game of musical pus by dumping the goo from one sink down another so you have to clean up that sink) and spray them out with a hose.
