How do I fit a Bottle Bumper?

Dry the outside of the bottle so the silicone grips, then stretch the bumper opening with both thumbs and slide it over the base of the Atomiser Spray Bottle or Foaming Spray Bottle, working it up until it sits flush. Twist the bumper so the colour-coded tag faces forward for easy identification at the sink. If it is hard to fit, a little soapy water or a damp cloth helps it slide.

Four steps to fit

1

Dry the outside of the bottle. A clean, dry surface helps the silicone grip.

2

Stretch the bumper. Hold the opening with both thumbs and gently widen it.

3

Slide over the base. Start at the bottom edge of Atomiser Spray Bottle or Foaming Spray Bottle and work the bumper up until it sits flush.

4

Twist to align. Rotate so the colour-coded tag faces forward. Soft food-grade silicone with anti-static oil adds grip and helps you spot the right cleaner at a glance.

✓ Bumper hard to put on?

Stretch the bumper gently before placing it on the bottle. Apply a small amount of soapy water or rub with a damp cloth to help it slide. Start from one side and slowly work it around for an even fit.

✓ Colour-coded for your cleaning system

Each colour matches a cleaner so there's no second-guessing at the sink. Yellow for kitchen. Blue for bathroom. Green for universal. Purple for stain remover. For the full breakdown, see How do I tell my bottles apart?

How do I clean and care for Bottle Bumpers?

Wash regularly by hand with warm soapy water and air-dry completely before refitting on the bottle. The antimicrobial coating helps resist bacteria, mould, and mildew. Avoid the dishwasher, bleach, harsh solvents, and abrasive cleaners, keep the bumper away from sharp objects, and store it in a cool, dry place out of prolonged direct sunlight. If it feels loose, dry the bottle fully or briefly warm the bumper under hot tap water to restore its stretch.

✓ Hand wash only

Wash regularly by hand with warm soapy water. Air-dry completely before refitting on the bottle. The antimicrobial coating helps resist bacteria, mould, and mildew, so a quick wash keeps the bumper fresh between uses.

⚠ What to avoid

No dishwasher. No bleach, harsh solvents, or abrasive cleaners. Keep away from sharp objects that could nick the silicone. Store in a cool, dry place out of prolonged direct sunlight.

✓ Bumper feeling loose?

Make sure the bottle is completely dry first. If the bumper still feels loose, warm it briefly under hot (not boiling) tap water for 10 to 15 seconds. The silicone softens, regains its stretch, and grips tighter once you refit it.

✓ Built to last

Food-grade silicone is resistant to heat, moisture, and UV exposure, and won't crack or become brittle like rubber. With proper care, a Bottle Bumper can last for years.
