Time lapse of a new car delivery wash,1st step vacuum inside then place down floor mats. Clean all inside windows . Remove all stickers and glue . 2nd stage outside wash . Spray buster on all rims and lower level of vehicle then do a good hand wash hood ,trunk , sides , windows then I like to use a horse hair brush for the roofs bottoms and rims . This technique will save your back from getting injured. ARDEX is the supplier for me . Next step squeegee the whole vehicle wipe out jams and dress the tires . this last tip I’m going to give will save you tons of time . Start the vehicle up turn up defroster grab a shame wipe down whole vehicle and your done .Outside windows will clear up. SUV WHEN dirty is about 35-40 sedans 25 minutes. Stick with this routine and you will never go wrong . Forgot to add after cleaning inside windows use the same towel to wipe down the inside.
