Sticky Gel Citrus Wheel and Rim Cleaner Gel is the most efficient and safest citrus-based wheel and rim cleaner that sticks to rims without dripping. Sticky Gel Citrus Wheel and Rim Cleaner Gel is ideal for cleaning all wheels and rims. The unique gel formula clings to wheels so the cleaner doesn't just run down the wheel quickly. The increased time in contact with the wheel allows the Sticky Gel to continuously break down road grime, brake dust, oxidation, oil dirt and more. The unique formula contains non hydrofluoric acid that makes painted wheels shine like new. The heavily concentrated formula can be diluted 5:1, which means one bottle will be enough for 1 liter of wheel cleaner or Sticky Gel can be diluted to fit desired needs. Use a heavier concentration for heavy deposits, the choice is yours. Once the formula works into the surface and begins the breakdown process, Sticky Gel can be simply rinsed away along with the loosened contaminants. For more stubborn stains re-spray the area and agitate with a soft cloth, brush or sponge. The pH neutral formula was specifically developed to work safely and effectively on virtually every wheel finish so you can use it with confidence, even on high end after market wheels. You can use it full strength for maximum cleaning power, but we recommend diluting it down to a 5:1 ratio of water to cleaner.
