The set includes a bottle of Rimblades Wheel Pre Clean Gel (70% alcohol) and 1 special sponge.
Use scissors to cut the sponge into 4 pieces, one for each wheel. Generously apply the cleaning gel to the sponge and thoroughly wipe and scrub the wheel rim in the area where the Rimblades will be attached. Turn the sponge several times and carefully scrub and wipe the entire rim edge with the sponge and cleaning gel.
This cleaning step removes stubborn care products such as sealants from the surface, allowing the adhesive to achieve proper bonding with the surface and ensuring that the rim protection functions correctly.
