Blackline Gentle APC All-Purpose Interior Cleaner 16 oz — Leather-Safe, pH-Balanced Formula

Blackline Gentle APC is a leather-safe, multi-surface interior cleaner that lifts dirt and grime from delicate materials without harsh solvents.

Designed for car enthusiasts and professional detailers, this 16 oz concentrated All-Purpose Cleaner (APC) cleans leather, suede, Alcantara, vinyl, plastic, carpet and fabric while minimizing risk to sensitive finishes. Its milder formula replaces aggressive degreasers for interiors where preserving texture and color matters most. Use diluted amounts for maintenance or stronger mixes for tougher soil, and apply with soft brushes or microfiber for best results.

How will this product treat leather, suede and Alcantara safely?

Blackline Gentle APC was formulated to remove soils from delicate surfaces without stripping dyes or natural oils. It cleans by loosening dirt gently so it can be lifted away with a soft brush or microfiber instead of aggressive scrubbing.

• Specifically pH-balanced to reduce risk of fading or stiffening.
• Use soft boar-bristle or ultra-soft brushes for agitation.
• Blot or lightly rub in circular motions, then wipe with clean microfiber.

What dilution should I use for different cleaning tasks?

Adjust the mix depending on how dirty the surface is: stronger ratios for heavy grime, lighter mixes for routine upkeep. Always test in an inconspicuous spot first to confirm colorfastness, especially on vintage or specialty leathers.

• Extreme dirt & grime: mix 1:1 with water.
• Moderate dirt & grime: dilute as appropriate (follow 1:1 guidance if unsure).
• Maintenance and light interior cleaning: dilute 4:1 (four parts water to one part cleaner).

Which tools and application techniques work best?

Spray the solution onto a brush, pad, or microfiber rather than soaking the material; this gives controlled cleaning power while preventing overwetting. For stubborn spots, allow the cleaner to dwell briefly before gentle agitation and removal.

• Spray on a boar-bristle or ultra-soft brush for textured surfaces.
• Use a clean microfiber to lift residue and dry the area.
• A scouring pad may be used carefully on durable fabrics — avoid on delicate suede.

How do I avoid damage when switching from stronger degreasers?

Stop using harsh degreasers on high-end interiors; switch to a gentler APC like Blackline to maintain suppleness and appearance. Work in small sections, rinse or blot thoroughly, and follow up with appropriate protectants if desired.

• Test a hidden area before full application.
• Don’t over-apply—less product with proper agitation is more effective.
• Allow surfaces to dry fully before using leather conditioners or fabric protectors.

Who is this for? Blackline Gentle APC is aimed at car owners, detail shops and anyone who cares for premium interiors—especially those with leather, suede or Alcantara—who want effective cleaning without risking damage. It’s also useful for household items and boat interiors where a milder cleaner is preferred. The 16 oz bottle gives versatility through dilution: use concentrated mixes for tough jobs or lighter blends for routine maintenance.
