Why You’ll Never Buy Blue Cleaner Again

Store-Bought:

  • Plastic jug (landfill)

  • Synthetic fragrances

  • Bleach + HCl

  • $6–$12 per bottle

  • Microplastics

  • Reusable glass jar

  • Real lavender + tea tree

  • Baking soda + citric acid

  • $0.18 per bomb

  • Zero waste

Eco win: One family switching = 12 plastic jugs saved per year.

Ingredients (Makes 24 x 1-inch Bombs)

  • 2 cups baking soda – Deodorizes + scrubs

  • ⅔ cup citric acid (food-grade) – Fizz + limescale buster

  • 30 drops lavender essential oil – Antibacterial scent

  • 20 drops tea tree essential oil – Kills germs

  • 1 tbsp dried lavender buds (optional) – Pretty + extra scrub

  • Witch hazel in a spray bottle – Binder (water activates too fast)

Pro tip: Buy citric acid in bulk—$8 for 5 lbs lasts a year.

Tools (All Reusable)

  • Large glass or stainless bowl

  • Silicone mold (mini muffins, ice cube trays, or DIY shapes)

  • Measuring cups + spoons

  • Gloves (citric acid tingles)

  • Airtight glass jar for storage

Step-by-Step: 20 Minutes to Spa-Clean Toilets

Step 1: Mix the Dry Base (3 min)

Whisk baking soda, citric acid, and dried lavender buds until uniform. The mix should look like fine moon dust.

Step 2: Add the Scent (1 min)

Drip in lavender and tea tree oils. Stir vigorously—the powders will clump slightly. Smell test: It should be spa-level heavenly.

Step 3: Bind with Witch Hazel (3 min)

Lightly spritz witch hazel (1–2 sprays at a time) while stirring. You want the texture of slightly damp sand—it holds when squeezed but crumbles if poked. Too wet? Add 1 tsp baking soda. Too dry? One more spritz.

Step 4: Mold the Bombs (5 min)

Press mixture firmly into your silicone mold. Overfill slightly, then scrape flat with a knife. Fun shapes: Mini hearts (Valentine’s vibe), 1-inch cubes (stackable), Flower molds (giftable).

Step 5: Dry Overnight (8–12 hours)

Pop the mold onto a baking sheet. Let cure in a dry, warm spot—not the humid bathroom!

Step 6: Unmold & Store (2 min)

Flex the mold to release. Store in an airtight glass jar labeled “Toilet Bombs – Drop 1, Flush Clean.”

How to Use (30 Seconds Flat)

  1. Drop 1 bomb into the bowl (no need to remove water).

  2. Watch it fizz for 5–10 minutes—citric acid eats limescale, baking soda scrubs.

  3. Brush lightly if needed.

  4. Flush. Done.

For tough rings: Drop 2 bombs + let sit 30 min before brushing.

Before & After (Real Results)

Before: Yellow limescale ring, faint odor, plastic bottle guilt After (1 Bomb): Sparkling white, lavender breeze, zero waste

  • Peroxide boost: +1 tsp 3% H₂O₂ for extra disinfect
