The product was recommended by my bike mechanic, the guy always sends my cars back in great condition and super clean. So I bought a five liter bottle and a separate atomizer. Contrary to other reviews, the atomizer cap worked well but the product performed just average on my cleaning task. To be honest I washed 5 pretty dirty ATVs/UTVs with this product in about 2 hours but I was hoping I could spray and rinse and the result would be the same as the bike mechanic did. But that didn't happen and all the cars needed an extra drying/wiping to look decent and in some situations where I thought the product was perfect (suspension parts, frame) it left marks, not much better than just under pressure to wash . Maybe my quads were too muddy to start, I'll try again with a less aggressive job, but at this point I think it's hard to justify the price of this cleaner.
