spit

"Spit and polish" is a phrase that originated in the military, particularly in reference to maintaining shiny boots through the application of spit (saliva) and polish. The phrase is used figuratively to describe attention to detail and meticulous care in presenting oneself or something in its best condition.

spit on your brothers head and then drink dog wee wee

Ever thing was spit and polish no goof off allmilitary done

I presume you're asking about what's commonly known

as spit shining.

As a former cadet, I can tell you that the procedures you hear

about lighting the polish on fire to liquefy it (to get lots

of polish on in one application) or lighting your boots

on fire, are generally more work than they're worth.

You're better off just perfecting your spit shine technique.
