There are a few things you can do to clean a spray bottle:

  1. Pour water into the spray bottle and shake it well. Pour the water into the spray bottle so that it covers the entire bottom of the spray bottle. Turn on the faucet and wait until the water starts to flow. Turn off the faucet and let the water run for a few minutes.
  2. Use a cloth or paper towel to clean the inside of the spray bottle. Make sure to dry everything off before putting it back in your tool box or storage area.
  3. Put everything away and forget about it!
