pH neutral wheel cleaner with red indicator Felgenblitz Säurefrei (Fb), 5 L

Koch-Chemie Felgenblitz Acid-Free (Felgenblitz Säurefrei) turns red as it reacts with brake dust, making it easy to see where the product is still active. Its thick gel formula clings to vertical wheel surfaces longer than conventional liquid cleaners, providing an extended dwell time.

Advantages:

— pH-neutral formula with a pH of 7.5, making it gentler than acidic wheel cleaners while remaining effective against stubborn contamination

— Leaves wheels glossy and water-repellent after rinsing

— Ready to use, with no dilution required

— Economical in use

— Original Koch-Chemie product

Areas of application:

— Aluminium, steel and chrome wheel rims

— Brake dust, stubborn grime and light rust deposits

— Sensitive wheel finishes, including polished aluminium, provided the product is tested on an inconspicuous area first

Directions for use:

Use in the shade on cool wheels. Apply the product undiluted and allow it to dwell for approximately 3 minutes. For heavy contamination, the contact time may be extended to 8–10 minutes.

If necessary, agitate the surface with a wheel brush, then rinse thoroughly with a pressure washer.

On sensitive wheels, remove any remaining product from the wheel bolt holes and dry them with compressed air. Repeat the application if deeply embedded contamination remains.

Do not apply to hot surfaces. Do not allow the product to dry on the surface.

Suitable for professional and private use.
