vinyl cleaning with wood glue....works?

Hi all,

I have been researching a way of cleaning vinyls and at a certain point I came across a particular way...looked really funky to me.
They are using wood glue and it looks like it works better than anything else.
My perplexity is if glue remains deep down then it can ruin the pick up.

anybody has ever successfully used this method?
What do you guys think?
