Tbh, I almost set my driveway on fire trying to change brake fluid.

Last month in my garage, I was using a cheap $15 hand pump to bleed the lines on my Civic and spilled a bunch of DOT 4 on the hot exhaust manifold. Honestly, it started smoking like crazy and I had to grab the fire extinguisher. What's the safest, idiot-proof way to do this solo without making a huge mess?
