The WoollyWormit Lug Nut Cleaner Sponge Replacement Kit includes 8 cleaning sponges total - 4 large sponges designed specifically for the large lug nut cleaner, and 4 small sponges designed specifically for the small lug nut cleaner.
In order for the WoollyWormit to effectively and safely clean your wheels without damaging the paint or clear coat surfaces, the lug nut cleaner was designed and engineered with our very own propriety sponge material. This proprietary formula balances the need for durability with our requirement to clean without scratching the surfaces of the rims. Because these sponges are durable, you'll most likely get a number of car washes per sponge. However, like any sponge they will wear out with usage. The useful life of each sponge is dependent on various factors: the specific spacing/tightness between the lug nut cavity wall and the lug nut itself, the sharpness of the lug nuts, how dirty the wheels are, and how hard you scrub. For this reason, we designed the lug nut cleaner frame to allow for the replacement of the cleaning sponges as needed.
The cleaning sponges are designed to be flipped over on the red lug nut cleaner frame once one end of the sponge is at the end of its useful life, so that both ends of the sponges can be used - offering you even more useful life before sponge replacement is needed.
Also keep in mind for some wheels, but not all, both the large and small lug nut cleaner will fit in the lug nut cavity areas. Maybe you're one of the lucky ones that can use both sets of lug nut cleaners for you wheels?
