Query: TOO EXPENSIVE AND STILL LEAVES WATER SPOTS

Not worth the cost; at a minimum of $1.00 per wash for ten washes that takes the cost of a wash for me to three dollars for everything..The thing that wasn't expected was I STILL HAVE WATER SPOTS..I did everything exactly as the directions stated; yet I still have water spots...After reading on the internet - ALLOT. I decided and made my own water deionizer. Use Both types of DI-Reson. One to soften the water and the second stage to Dionize the water.Know what? NO WATER SPOTS..It cost me $200.00 for all the parts; BUT I can reuse the reson by regenerating it..I also don't have to do this for around 1,000 gallons of water, so the cost is way lower.
