Another interesting thing about rinse less is the fact people(some) say a bottle will last a long time and it's cheap. If you use rinse less 90% of the time like me rinse less is more expensive than regular soap. I never understood that marketing ploy - another from OPT/Ivan probably. i use more rinseless per wash than soap - usually just 1oz of reset in 15 liters of water for instance.
I think rinseless is cheap.
Let's use Klasse's Carbon Collective example which is on the higher end of rinseless cost. $25.00 (including tax &shipping) for roughly 16 ozs. If he can get 16 washes out of that bottle then that's $1.56 per wash. Compare that to $10.00 per wash at the scratch em up automatic tunnel wash which that $10.00 is on the low end plus the gasoline to get there.
Other rinseless washes are much less expensive. I recently paid $41.00 ,including taxes for a gallon of Duragloss 932 which I believe is a very good rinseless wash. That breaks down to 48 cents per wash considering one is using 3 gallons per wash which is very reasonable at 1/2 gallon for the presoak and 2.5 gallons for the bucket wash. That's crazy cheap.
Makes one wonder why anyone would go to an automatic car wash. At least is Makes me wonder.
