GE's latest dishwasher, the GDT720SSFSS (MSRP $1,049) features a dedicated Bottle Wash option. It's designed to clean the insides of reusable bottles with dedicated spray jets. It sounded intriguing, so we put it to the test.
First, we got our hands on three of the most popular reusable bottles in the US: a 16 oz wide-mouth plastic sports bottle, a 32 oz narrow-mouth plastic sports bottle, and a 9 oz baby bottle. The baby bottle got filled with infant formula, while the sports bottles got filled with a green fruit and vegetable smoothie mix.
After 2 hours, we poured all the juice and milk out of the bottles, leaving the residue behind. Then, we left them to sit for 72 hours, uncovered—just as your used smoothie bottle might sit in your gym bag and then in the dishwasher, waiting to be cleaned. They were all pretty gross.
When it came time to wash the bottles, we put them in the top rack of the GDT720. The left side looks just like a regular dishwasher rack, but the right side features Bottle Wash spray jets on the ends of the tines. Bottles are designed to sit on top of those jets, which then blast off all the residual soil. So we could make an accurate comparison, we washed the control group on the left, and the test group on the right during the same cycle.
Once the wash cycle finished, the difference was clear: Bottle Wash really did help clean the smoothie residue off the narrow-mouth bottle. The control bottle was still filled with caked-on smoothie nastiness, but the one cleaned with Bottle Wash was as good as new.
The differences were less apparent with the baby bottles and wide-mouth sports bottles, however. All of them ended up clean, regardless of where we put them on the top rack.
The message in this bottle? GE's new Bottle Wash works in tricky situations.
