I bought a drum of tfr cleaner too wash the tractors with,put it in a spray bottle maybe 4 litres too 1 water,sprayed tractor then washed of with powerwasher,did great job with the dirt and grime,but after drying paintwork was faded,a whiteness on it and you could rub it of with ur finger,i had too t cut it too get it back too normal,both case and john deere the same,whats the wright way too use it,more watered down or none at all?
