It could still be teflon tape; after it gets used, I find that it does turn transparent. In any case, a photo would be much more helpful, particularly for the next part.

This sounds like there is an additional valve for adjusting flow, in addition to the regulator. You can probably remove this to clean up the appearance.

Once again looking right now you have adjusting knob then hex nut connecting to the T pointing up which goes to the solenoid, then extending with threads directly to the regulator, this is where I noticed some kind of solvent that is clear looking. Not tape.
Thats it: My guess is that small hex needs to come out to get at the needle valve & then replace with new one.
A photo is needed. If it is an actual T, then the needle valve can go into the T. In general, needle valves go after the solenoid as well, so I am unsure exactly what kind of setup you have.

No name brands tend to have unusual/proprietary fittings, so you may need additional adapters and/or fittings as well.
