What is your routine for washing the Y. What products do you use. The first time today washing it and with all this glass it was not easy. Not only do you need a lift to get to the center of the car, because it is also quite tall, but it was also difficult to get the glass streak-free. Seemed like the time it took to wash and dry was almost double of other cars I have owned.I
I wash my Model Y by hand using either a small power washer or Optimum No Rinse.
Power washer method:
1600 PSI power washer
Soap cannon (their are many styles, choices of soap attachment for use with a pressure washer.)
Foaming car wash soap (designed to work with a soap cannon)
Various wide spray nozzles for use with the power washer (you want a wide spray nozzle to avoid damaging the paint, tires etc.)
2 buckets; one for washing the other for rinsing your wash mitt or sponge. At least one good grit guard (for the rinse bucket if you only have one guard.)
Microfiber wash mitt *
Large microfiber towels * for drying the glass and paint (2 minimum)
Microfiber mop * with extendable handle (makes reaching all of the glass roof, windshield and rear glass easy.) Like this one:

Optimum No Rinse (ONR) Method: (Great for winter when it is too cold or when your vehicle only needs a light wash.)
1 bucket
1 good grit guard (not all grit guards are the same, some actually do keep most of the dirt at the bottom of the bucket.)
2 gallons of water (does not have to be distilled water)
2 capfulls of Optimum No Rinse Wash and Shine (it's blue); there is also ONR Wash and Wax (it's green)
1 cross cut sponge (Big Red Sponge or competitor's product) else about 2 to 3 dozen small microfiber wash cloths* (I use a a large cross cut sponge, don't want to have to wash a couple of dozen micro fiber towels after washing the vehicle.)
1 spray bottle filled with ONR solution from bucket, for presoaking extra dirty panels with ONR before wiping off the panel.
3 or more medium size microfiber towels for wiping off ONR from each panel, side of vehicle as you go.
Note: ONR can be used on glass with excellent results. Else I use Invisible Glass and small micro fiber wash cloths to clean the inside and outside windows, windshield, rear hatch glass of the model Y.
* Always rinse, wash microfiber towels, wash cloths etc. in cold water. Never use warm or hot water with microfiber cloth. Air dry only (no heat) as the dryer heat will damage the microfiber material.
