The 'blue' scourers are only available as scourer/sponge combos AFAIK.
Just checked under the kitchen sink, and it seems that Scotch-Brite have changed their no-scratch scourer/sponges to a green coloured scourer - the attached sponge is still blue, however. The viscose sponge side of these is really good for grease removal, BTW. Aldi have some no-scratch scourer sponges that are white scourer/yellow sponge.
Regular car wash is OK, but steer clear of the likes of CT-18 Truck Wash.
I actually use cheapo shampoo to wash my motorcycles, on the recommendation of my bike mechanic. Car washes can be a bit corrosive to aluminium alloys, especially that CT-18. Shampoo is neutral pH, it still gets the paintwork clean, and it rinses off easily.
