Help me decide if a CR spotless system is worth the money? 
I figure that a 2.5gpm pressure washer used for 5 min each rinse uses 7.5 gallons.
If I wash the car 2x per week that would be 15 gallons each week.
15 gallons per week is about 780 gallons per year (15x52).
The most cost effective unit is the 300 gallon one. If I buy that with 2 refill cartriges it will cost $410 plus shipping so about $450.00. The cost per gallon becomes $450/600 gallons, or $.75 per gallon. The yearly cost becomes 780 gallons X $.75 or $580 per year.......:shocked:
Is it worth $580 per year for spot free rinsing????
