K2 APC STRONG PRO 1L
Maximum power against toughest dirt
PRO DETAILING SERIES
Mastery over stubborn dirt
Say goodbye to stubborn grime that just won’t budge. The K2 APC Strong Pro is your ultimate tool when gentle cleaners reach their limits. This highly alkaline power concentrate was developed as a All-Purpose Cleaner (APC) specifically for the toughest tasks in vehicle detailing – from oil-soaked engine bays to heavily soiled interior plastics.
Recommended use for APC Strong Pro:
Since this is a highly effective concentrate, the correct mixing ratio is crucial for success and material compatibility.
Mixing ratios:
- 1:10 ( 100ml per 1L water): For extremely heavy dirt (e.g. engine bay, wheel arches, heavily soiled door sills, stain removal).
- 1:80 ( approx. 12ml per 1L water): For light dirt inside and for regular maintenance.
Step-by-step instructions:
- Mixing: Prepare the appropriate dilution in a spray bottle .
- Application: Spray the solution onto the cool surface to be cleaned (for interiors, better spray directly onto the brush or the microfiber cloth to avoid spray mist).
- Work in: Use a detailing brush or a soft brush to foam up the product and effectively loosen the dirt.
- Removal: Wipe off the loosened dirt thoroughly with a clean, damp microfiber cloth.
- Rinse off: When used outdoors (e.g. rims/engine), rinse with water. Indoors, wipe again with a second damp cloth to remove alkaline residues.
Suitable surfaces:
K2 APC Strong Pro is an alkaline cleaner. It is extremely effective but requires caution with sensitive materials.
- Inside the vehicle:
- Hard plastics (door sills, pedals)
- Painted surfaces
- Fabric upholstery and carpets (ideal for pre-treating stains)
- Vinyl floors (e.g. in vans)
- Outside the vehicle:
- Plastic trims (wheel arches, bumpers)
- Tires and rims (ideal pre-cleaning)
- Engine bay and mechanical parts
- Paint (as pre-wash against insects and road film)

What makes K2 APC Strong Pro special
The unbeatable efficiency of Strong Pro: The unique feature of K2 APC Strong Pro is its ability to "kill dirt" where others give up. It’s the "wrecking ball" among cleaners: When you need to detail a neglected vehicle or dirt has been stuck for years, this is the go-to product. Despite its strength, it can be removed faster than conventional cleaners thanks to the "Low-Foam" technology, saving you valuable time.
Detailed description of the all-purpose cleaner
K2 APC Strong Pro belongs to the professional "K2 Pro" line and is aimed at detailers and enthusiasts who want no compromises. Its chemical composition is alkaline, meaning it chemically breaks down organic dirt such as grease, oils, insect residues, and road film (saponifies).
Compared to pH-neutral cleaners, it penetrates deeper into the structure of dirt. It is excellent as a Pre-Cleaner before the actual car wash to loosen coarse dirt without stripping the wax layer completely (at high dilution). Indoors, it’s a savior for light plastics darkened by shoe scuff marks or fabric mats harboring deep-seated dirt.

Frequently asked questions about K2 APC Strong Pro
🎨 Does the cleaner attack my car paint?
At the correct dilution (1:10 to 1:80), it is safe to use on paint as long as it doesn’t dry in direct sunlight. It’s great for loosening old wax layers or removing insects.
🔧 Can I use the cleaner on sensitive interior materials?
Yes – the cleaner is versatile, but due to its strong cleaning power, we recommend a moderate dilution (e.g. 1:80) and a prior test on particularly sensitive materials.
💺 Can I also clean my fabric seats with it?
Yes! 🧼 Strong Pro is excellent for fabric upholstery and floor mats. Use it as a pre-spray for extraction cleaning or work it in with a brush. Always test colorfastness on a hidden spot first.
❄️ Is it suitable for Alcantara?
For Alcantara and very sensitive leather, we recommend K2 APC Neutral Pro or special upholstery cleaners . Strong Pro could harden the fine fibers if used incorrectly.
⚡ What is the difference to K2 APC STRONG PRO?
The Neutral Pro is pH-neutral and gentle on materials – ideal for regular cleaning.
The Strong Pro on the other hand is strongly alkaline, more aggressive, and designed specifically for extremely dirty areas like engine bays, wheel arches, or commercial vehicles.
🛠️ Is the product also suitable for the engine bay?
Yes, you can use the cleaner in the engine bay – just make sure to use the correct dilution and avoid direct application on sensitive electronics or hot parts.
