Diablo wheel gel works exactly as described, can handle the Canadian winter wheel grime with NO problem. I mixed it 1:4, sprayed the grimy, salty wheel and thirty minutes later, rinsed it off with water from a low-pressure garden pump sprayer (can't use the hose in midwinter.) The wheels were so clean, they looked white. A quick wipe, NO residue, no grit, just clean with NO effort. Great product, great value, great for green-regulated areas.
