A mate proudly showed me his new plastic taps, solid black.
I shake my head and show him my tap cleaning jar, holding a white tap up to the light you can clearly see the gunge inside it, which leads you to remove it from the fermenter, whereupon you discover the gunge in the threads of both tap and fermenter.
My process: remove tap, brush out the threads on the fermenter and copiously spray with starsan, put the tap in boiling water to soften, using towel/gloves and superhuman effort pull tap apart, brush out any crud and store the two parts in a jar full of starsan.
When needed, reassemble the tap using food grade silicon lube, if you omit the lube the tap WILL! drip.
Not saying the black taps are bad, just if we can't see it the assumption is that it's clean.
Sorry if this has been covered elsewhere, just worth stressing imho.
btw, after 2 hrs of trying to pull a tap apart (please don't use the you tube method of using a screwdriver and banging it on a bench)
Please send $200.00 to "Grmblz @ I will take your money" for a free video on how to do it. Spoiler alert, it uses vice grips.
