I did this while I was doing the clean a bathroom BB.
To complete this BB, the minimum requirements are:
- Clean/decalcify a faucet aerator
To show you've completed this Badge Bit, you must show proof of the following (as pictures or a video < 2 mins):
- Dirty/calcified faucet operating poorly
- Cleaning/decalcifying the faucet
- Newly cleaned/decalcified faucet operating properly
- A description of the method for how the faucet aerator was cleaned/decalcified
Dirty faucet
Vinegar bath
Brushing off gunk
Clean faucet
I put rice vinegar in a ziplock bag and rubber banded it to the faucet for 30 minutes, then gently brushed off the gunk with a toothbrush (and used some fingernail to clean off the rest of the stuck on gunk).
