Glass Cleaner Concentrate

50mm, F/3.5, 1/200s, ISO160

There're just a few drops of NXT Glass Cleaner left in the bottle. If I'm not wrong, I got it during the KLIMS 2006, it lasted me almost 2 years. Today I dropped by Meguiar's to pick up a bottle of Meguiar's Glass Cleaner Concentrate (1 gallon) and its 32oz spray bottle and chemical resistant sprayer. This product belongs to the Detailer Brand and it's meant for the production line. Similar to Safe D-Greaser, it's dilutable in the ratio of 10:1. From this bottle of liquid, I can dilute it into 11 gallons of glass cleaner! Let's calculate the cost of every mL as compared to NXT Glass Cleaner...

Glass Cleaner Concentrate's Price: RM115.50
Diluted Volume: 11 gallons = 41.627L
Price per 100mL: RM0.28

NXT Glass Cleaner's Price: RM38
Volume: 24oz = 0.7096L
Price per 100mL: RM5.36

This simple calculation shows that the NXT Glass Cleaner is more than 19 times more expensive than Glass Cleaner Concentrate. It's suitable for people like me who wipes down the glass daily, or even a few times a day.
