This is more complicated than I expected![]()
It really isn't and after a few times you'll do it without thinking.
It's just like when you use washing up liquid if your washing a plate that you made a sandwhich on you'll put a drop on the sponge if your washing a casserole dish you made a pasta bake with you'll put more on there because it's dirtier but honestly read the link Lee done it's pretty much the definitive write up, the mods should make it a sticky thread! (just Lee's bit).
To avoid disappointment use Bilt hamber or wax planets 8 below don't be tempted by anything in halfords and then just go for it if anything it's makes cleaning your car much more enjoyable.
Everyone will sigh over your question because it has been asked for years but don't be put off to ask questions that's what the forum is here for.
