Feynlab All Purpose Cleaner | Concentrated Dual-Action APC | Interior & Exterior
Feynlab ALL PURPOSE CLEANER — One Concentrate, Dialled to the Job
Most "all purpose" cleaners lean one way — either citrus-based for organic grime, or alkaline for inorganic soils. Feynlab's APC runs both systems together in one dual-action formula, so body oils, food, road film and workshop grime all come off with the same product.
Because it's a true concentrate, the cleaning strength is controlled by dilution, not by reaching for a harsher chemical. Mixed light (Feynlab suggests starting at 1:80 for leather and Alcantara), it's gentle enough for routine cleaning on delicate interior materials. Mixed strong, it handles the heavy degreasing jobs professionals deal with daily. Same product, same chemistry — just adjusted to the task.
It also earns its place in a coated-car routine: when contamination build-up starts masking the hydrophobic behaviour of a ceramic-coated surface, a proper APC wash helps reset it.
KEY FEATURES
- Dual-action chemistry — citrus and alkaline cleaners in one product, targeting organic and inorganic soils together.
- Dilution controls strength — light ratios for interiors and routine cleaning, stronger ratios for heavy grime.
- Safe on delicate materials at the right dilution — including leather and Alcantara.
- Coating-friendly — helps restore hydrophobic behaviour on contaminated ceramic-coated surfaces.
- Professional-grade but DIY friendly — True Series, no guesswork required.
DILUTION GUIDE (Feynlab's published ratios):
- 1:10 — heavy soiling, grease build-up, engine bays and wheel wells (1 part APC to 10 parts water).
- 1:50 — general cleaning of interior plastics, trim and lightly soiled surfaces (1 part APC to 50 parts water).
- 1:25 — sits between the two. Feynlab lists it in its dilution chart but doesn't assign it a specific job.
- 1:80 — Feynlab's starting point for leather and Alcantara. Increase only as needed.
Working solution from a 1L bottle (Feynlab's chart): about 51L at 1:50, 26L at 1:25 and 11L at 1:10.
HOW TO USE (Feynlab's directions):
- Dilute with clean water to the ratio that suits the job. Never apply the concentrate directly to a surface.
- Apply the diluted solution with a spray bottle, brush or microfibre towel.
- Let it dwell briefly to loosen contaminants, then agitate as needed with a soft brush or microfibre. Feynlab doesn't give a dwell time.
- Don't let it dry on the surface.
- Once the contamination is lifted, rinse thoroughly with water, or wipe clean with a damp microfibre towel, depending on the area.
- Interior: finish with a clean, dry microfibre towel to remove excess moisture and leave a streak-free finish.
SURFACE NOTES (Feynlab): After cleaning leather with any all purpose cleaner, treat it with a leather conditioner or hydrating product to restore moisture. On chrome, start with the weakest dilution possible and test an inconspicuous area first. Fabric and carpet: spot test first.
APPROVED SURFACES (Feynlab): painted and clear-coated surfaces · plastic and vinyl trim (interior and exterior) · rubber components and seals · engine bay components · wheel wells and suspension components · fabric and carpet (spot test first). Feynlab also lists wheels with non-sensitive finishes. Feynlab says not to use it on surfaces it doesn't list.
CAUTIONS (Feynlab): Always dilute before use. Wear protective gloves and eye protection when handling the concentrate. Avoid prolonged skin contact and eye exposure. Use in a well-ventilated area. Don't let it dry on surfaces. Store tightly sealed in a cool, dry place away from direct sunlight. Keep out of reach of children.
SHELF LIFE (Feynlab): unopened 2 years · opened 12 months in a normal, climate-controlled environment.
