Just be careful it doesn't contain salt if you're leaving a chain to sit in it, as it'll start to rust! You'll see the same if you clean drivechain components with washing up liquid or baby-wipes. I use
this, almost as cheap as yours and may work better as it's a dedicated industrial strength degreaser.
As for power/master/quick-link removal, 'invest' in one of the real tools. I picked up an X-Tools (CRC) or Lifeline (Wiggle) one in one of their regular sales for about £3.70. Saves so much time & hassle! Previously I had bent the noses on an old pair of needle nose pliers into moon shapes to fit them, worked ok but would mark links and could be fiddly on a slippy lubed link, wouldn't recommend. In an emergency I previously used a combination of zip ties and swearing, wouldn't recommend that either!
I'll just leave this here (hard winter, salted roads commuting & lots of mud & miles)...
