Cleaning Product Recommendations

[C.A.R.]

I'm not a 'detailer' by any means, but I like to clean my car and my dads car at least once a month to a decent standard.

I'm very low on -
Wheel Cleaner
Tyre Shine
Tar / Bug remover

I'm used to using AutoGlym products as they were always on offer at Halfords and seem pretty decent. I recently bought some Auto Finesse Citrus Power but other than smell nice it didn't budge any of the road grime. It worked through some green mossy type stuff which had built up behind the boot spoiler and that was about it. IMO, it's crap.

So what can you recommend? Bear in mind I don't spend forever doing my car and don't want to have to buy extra equipment! I just use the ol' 2 bucket method.
