Cheers, going by the replies here on TFR, I'll stick with snowfoam. Currently using AG Polar Blast but have a tub of the Halfords Advanced stuff to try next as it was on offer last time I was in store so I grabbed a pack of it.
Interested to try as you suggest, adding some citrus pre-wash or APC - any in particular you would suggest/recommend? I usually wash my car using a three stage method - AG Polar Blast, AG Polar Wash then finally AG Polar Seal. Then dry off using microfibre towels. But that all takes time and at this time of year when the car gets dirty much quicker (also depending on the weather) it would be nice to be able to just rinse off with water, apply some sort of 'solution' to the car, leave for a few minutes then rinse off, getting the worst of the crap off and saving time rather than go through the full 3 stage treatment that I would usually do.
Quite demoralising doing the full three stage thing, drying the car off then popping to the shops for a 5 minute drive and by the time you get home the damn car is filthy again, due to the crud on the roads!!!
