The Heavy-Duty Wheel Cleaner is a powerful all-purpose cleaner that gets right into your wheel wells to break down the toughest build-ups of dirt, brake dust, and grease or contamination caused by the breakdown of surrounding metals at high temperatures. The HD wheel cleaner is safe, versatile, and extremely powerful. It is crucial to thoroughly saturate the area you want to clean – the powerful wheel cleaner works best when you saturate the complete wheel. It’s best to work out of direct sunlight. We recommend you wear gloves during the entire process.
