    Shower heads often hide more grime than they show. Hard water deposits, soap scum, and mineral buildup can silently clog nozzles, reduce water pressure, and dull the shine of your client’s bathroom fixtures.

    As a professional cleaner, your job is to restore—not just remove dirt, but revive function and finish. The key? Using the right method and the right product.

    That’s where Scum Bum, powered by glycolic acid, comes in.

     Why Scum Bum Works

    Scum Bum is formulated with glycolic acid, a highly effective yet safer acid that:

    • Dissolves mineral buildup like calcium and lime

    • Breaks down soap scum and light rust stains

    • Penetrates residue without damaging surfaces

    Unlike harsh industrial acids, glycolic acid offers the power you need without toxic fumes or gloves, making it ideal for professional use in client homes and commercial spaces.

    To get professional results, you need the right tools. Here’s what we recommend for cleaning shower heads safely and effectively—without harsh chemicals:

    Scum Bum – Glycolic acid–based cleaner that dissolves mineral deposits and soap scum without toxic fumes.
    Speed Cleaning Cleaning Toothbrush – Firm-bristle brush designed for detailed scrubbing (not for teeth).
    Microfiber Cloth – For drying and polishing to a streak-free, professional finish.

     Step 1: Start with a Dry Shower Head

    Dry the fixture before spraying. This allows Scum Bum to grip the buildup instead of being diluted by leftover moisture.
    Even a quick wipe makes a difference.

     Step 2: Spray Scum Bum Generously

    Apply Scum Bum over:

    • The face of the shower head

    • Nozzle openings

    • Seams and joints

    • Underside of the fixture

    Let it sit for 2–3 minutes. The glycolic acid will begin dissolving tough deposits on contact.

     Step 3: Scrub with a Detail Brush

    Use the Speed Cleaning Cleaning Toothbrush — a professional-grade brush with firm bristles (not for dental use!) — to scrub with precision:

    • Around clogged nozzles to dislodge mineral deposits

    • Along edges and seams where grime builds up

    • Nozzles (to unclog spray holes)

    • Edges and crevices

    • Any remaining visible buildup

     

    Step 4: Rinse and Run Water

    Rinse the shower head thoroughly with warm water to remove loosened grime.

    Then, briefly turn on the shower to let the water flow through the nozzles.
    This helps:

    • Clear out any internal buildup that may have loosened during scrubbing

    • Ensure all spray holes are working evenly

     

    Step 5: Dry and Buff

    Polish the surface with a clean microfiber cloth. This removes water marks, prevents streaks, and delivers a finish that impresses clients at first glance.

    Deliver More Than Clean—Restore Performance

    Most homeowners don’t notice their shower head buildup until it affects water flow.
    But when you include this detail in your weekly, biweekly, or monthly service, you stand out as a professional who goes the extra step.

    With Scum Bum and a little know-how, you deliver:

    • Functional improvement

    • Visual impact

    • A safer, more efficient clean

    All thanks to glycolic acid—a pro-approved ingredient that works hard, without working against your health.

    Your clients may not notice buildup—but they will notice the difference after you’re done.
    Scum Bum helps you deliver that “wow” moment, every time.
