Help cleaning my straight razor and scales

[Riaanrab]

So i bought this straight razor and it need some good cleaning. Doing some research here on the site and reading what other people do on cleaning there straights i want to get some ideas for my own straight.

I live in South Africa and this is what i can get as a metal polish "Brasso" Brasso Metal Polish 200ml | General | Cleaning Products | Household | Food & Household | Woolworths.co.za | Food, Home, Clothing & General Merchandise available online!

will this fine to use on the blade and on the scales???? i do not have and power polish tools or machines, so everything i will do will be by hand. i also do not want to seperate the blade and scales because i have no idea where to buy new pins or even to take it apart and put it back together.

I read that after shaving you put some oil on the blade for protection, my barber said i must but thin layer of vaseline on, is that ok or not.
