The bottle says will not leave residue or spots.. HAHA , My truck spoted so bad I had to go over the whole truck 3 times with a micro fiber wet rag.. Now I know the best way to wash my truck is to use a wet microfiber sponge with water and a dry microfiber rag to gently wipe.. The heck with all car soap . Especially armour all

 

That's a terrible plan. Car soap not only aids in the cleaning process but also provides lubrication so you don't scratch the paint. Unless you dry properly, you're probably going to always have water spots. I don't recommend your new found method unless you like the look of vehicles riddled with swirls. Invest in some Optimum No Rinse if you want something similar but safe.
