Applying badge on waxed car

[iacabu]

I've just bought my clio and it has the cup 172 badge missing off the B pillar on one side. The seller tried to apply it but said wouldn't stick properly due to the wax.
How can I best remove the wax to apply the badge?

Also, when I was my car how often do I polish and wax it? Can I polish on top of wax?
If I was to buy a clay bar do I go over the car with that and then reapply polish and wax?

Sorry for all the questions!

tar remover is good i used that on my paint before fitting cup badges,it wont stick to a waxed surface needs to be squeaky clean even washing up liquid will work,dont polish over wax it removes wax,you can wax as much as you want.Get the paint as clean as poss before waxing for a better finish

Clean area with washing up liquid (diluted) or LSP remover if you have any, then apply. Polish/wax after.
