I've just gone through the process of starting to clean out the inside of my tank via the 'coca cola' method just to start things off. Quite a fair bit of gunk came out but i've been left with this odd thing inside (see attached)?? I'm making an assumption here but i'm thinking that it's part of an old liner that has come away from the inside wall. Whatever it is, what would you recommend is the best way to get it out and further clean the tank?
As mentioned in my first post, i am a complete novice with all of this so i may need a bit of hand holding!

That does look like an old liner, but before you remove it, ask yourself why was it there in the first place? If you want to remove it, acetone should do the job. Once that’s out of the way there are several methods of cleaning your tank up - I use vinegar, fill it right up and leave it a couple of days then empty it, serve it and put it back in until it’s clean and no more gunk comes out. I have also used the electrolysis method which works for getting rid of rust too.
Or you can send it off to someone like Hartlepool radiators who will clean it out for you and professionally reline it, but it costs around £200.
