Do Not use dish soap!
Do Not use bleach if you can help it. It works, but with the sanitizers available today you don't need it, and it can react with some metals.
Do Not rinse Star-San......it doesn't leave off flavors. Hundreds of people use it without any problems.
Do rinse PBW then spray with Star-San
I'd get another bucket and tubing for starters.
Leave it on the yeast for 2 weeks. Racking too soon can cause some off flavors.
Fermenting in the low 60's is good for many styles so that's probably not part of the problem.
It's not uncommon for infections to happen after bottling if good sanitation isn't followed, and can take weeks to show up.
Start with a new bucket and tubing, then practice good sanitation. Use bottled or RO water and see if that clears it up.
Don't give up....we've all had issues at one time or another. Once you get it figured out, you'll be glad you stuck with it!
