I had this same stuff in the past. It ruined 4 batches of brew, because I continued to use the same plastic funnel. Same ropey looking strands in the wort.
Hate to say it, but for me, I ended up dumping the whole mess. The smell will confirm. If it smells like rotten veggies, save yourself the heart ache, and feed the fishies with it...Be careful of using the same plastics afterwards....I sanitized with double the chlorine to save my stuff. BTW I bottled all four batches and they all foamed over and tasted like crap. I had some of the bottles actually explode in the cases...If you did bottle, isolate the bottles from the rest of your stuff...That infection will spread if the bottles explode!
Good news, that was 5 years ago and I have not had any issues since. I replace all my tubing though, as well as my funnel.
With regard to cleaner, I have always used bleach (1/2 c per 5 gal) and I am using the same bottling bucket I got 20 years ago...However I always ferment in glass, never in plastic.
