Its a used tank should have cleaned and boiled everything but i didnt foung 2 types of snail as well comon pond snails and ones with spiral shells no fish

Ok. So I guess my question is do you want the snails?

I'd go about this two different ways.
Take what snails I want to keep out and then clean everything and put them back in when I was done.

Or just break the tank down and clean everything.

If you are cycling right now you can run your filter in a bucket to keep it alive till everything is clean.
I would say salt the tank to get ride of the snails and hopefully the slug looking things, but since I don't know what they are I'm not sure salt will kill them. And then you'd have to do lots of water changes to get things cleaned up. So really I think it would just be easier to go back and do the cleaning that you skipped.
Sometimes we end up finding out steps we thought we could skip just set us back in the long run:/
