What?
Iv'e just bought a 25 litre, I'll see how good it is on the work vans and post back
That's a handy amount for cleaning an aircraft carrier.
Would you really need that much, considering I use 100ml per 1l bottle, that normally gets through 4 cars at a high mixture rate, it would take you 1234 years to make a dent in that.
Plus regular use of a tfr I'm sure would not be good for the paint, plastics and rubber.
Have a look at something like megs hyper wash or a valet pro product in 5l form. Will be a much better product and safe for regular use.
