Krystal Kleen Detail’s ‘A-Kleen’ APC is a highly concentrated multipurpose cleaner. It can be diluted up to 100:1 whilst still maintaining excellent cleaning power. When used at higher concentrations, it can be used to remove even grease and oil deposits from vehicle interiors. It is primarily aimed at vehicle interior cleaning from hard surfaces to fabrics and even leather. It is completely safe on all surfaces and is completely non-caustic. This means it will not stain trim or glass as will some APC’s that are corrosive in use. It is also pleasantly lemon scented and leaves your car interior smelling as fresh as it looks.
