Oh sooo many opinions, so many options…
I am sure the very experienced people will jump on here and advise what they think is best… But it’s more a choice of budget, and application purpose and what suits you best..
Do you have a jet wash and a snow foam Lance? Do you need that?? Alot of people use citrus based pre wash through a garden weed sprayer pump (with good effect to)…
Then there is the waterless washing (handy if no access to hose and some are environmentally friendly)…
Other cleaners attack your wax.. No real issue if you wax often or use a decent wax…
For me I have
Bilt hammer Auto wash (snow foam)
Bilt hammer car wash (small bottle last ages)
3M clay Mitt (although have a few bars aswell, but Mitt works well for the most of it)
Bilt hammer fall out remover (forget the name- but it’s cheap and effective for me)
Bilt hammer wheel cleaner (very good - but plenty out there to choose from)
If you have a DA polisher then your ready for Polishing with a machine, research for me suggested a good place to start with was megauirs 205 polish and 105 cutting compound would do most of the jobs I wanted and tbh u haven’t needed to use the 105 stuff yet as the 205 is very good for removal of swirls, light scratches etc..
Wax I use colinnite 456s, very cheap, effective and easy to use… But once again there are others out there such as show waxes etc.. Depends on what you want..
Then I use a quick detailer of BSD with chemical guys V7 mixed 50/50.. However BSD (available at euro car parts cheap atm) is very good on its own…
I have alot of bill hammer stuff, mainly down to cost and availability and it works well… If you have an autosmart guy near you who will sell to you you can get alot trade stuff that’s also very good…
But as I say many different options out there…
