Simply drop one pre-measured dark blue WASH-IT PAK-IT into its matching quart trigger spray bottle (sold separately) and add cold, tepid or warm water. Wait two minutes and shake. Adjust nozzle to mist setting and then just spray and wipe off with a clean microfiber cloth or ideally a paper towel. WASH-IT's formula is safe to use on all interior surfaces yet powerful enough to remove bird droppings, bugs, road tar, dirt and oil from the vehicle's exterior. Ammonia-free. If you don't want to mess with a bucket, hose and sponge then try the quick and easy alternative WASH-IT.
