FAQ

Can I spray D101 directly on instrument panels?

Use a towel or brush instead of direct spraying to avoid oversaturation. Wipe dry and follow with a protectant if needed.

Is the 4:1 dilution safe on wheels?

Yes for painted and clear-coated wheels. Rinse promptly and avoid bare aluminium or chrome without testing.

Do I need to rinse after a 10:1 interior clean?

Blot and wipe with a damp microfiber to remove residue. Follow with a dry towel to prevent streaks.
