What are Koh Grout Brush and the pole made of?
Grout Brush has a polypropylene (PP) handle with polybutylene terephthalate (PBT) bristles bundled into the head. Grout Brush Pole is a polypropylene grip with a stainless steel shaft. Both are rigid plastics engineered for cleaning durability, not single-use disposability.
Handle
Polypropylene (PP). Lightweight, durable, and recyclable in some kerbside programs. Check your local council guidelines for rigid plastics.
⚠ Bristles
Polybutylene terephthalate (PBT). Engineered for scrub durability. Not widely accepted in kerbside recycling streams.
Pole (optional)
Polypropylene grip with a stainless steel shaft. Mixed materials, so check local recycling for metal separation options.
Can I recycle Koh Grout Brush in kerbside recycling?
Not as a whole unit. Grout Brush combines a PP handle with PBT bristles that can't be separated at standard facilities, so most kerbside streams reject it. Some councils accept rigid-plastic items like brush handles in specific programs. Check your local recycling guidelines before binning. When uncertain, general waste is safer than contaminating recycling.
⚠ Mixed materials
The PBT bristles are bonded into the PP handle and can't be separated at standard facilities. Mixed-material items usually get rejected by kerbside streams and sent to landfill.
Check local council
Some councils accept rigid-plastic items in specialist drop-off programs. Search your council website for brush or rigid-plastic recycling before binning.
What should I do with a worn Koh Grout Brush?
Downgrade worn Grout Brush to outdoor jobs first. Once the bristles soften for indoor grout work, they're still effective on outdoor tiles, BBQ grates, garden pots, tool handles, muddy boot soles, and bike chains. When the brush is fully worn down and can't serve any job, place it in household general waste.
✓ Reuse for outdoor jobs
Softened bristles still work on outdoor tiles, BBQ grates, garden pots, tool handles, muddy boots, bike chains, and patio furniture. Stretches the brush well beyond its indoor-grout lifespan.
Final disposal
When the bristles are fully flattened or the handle cracks, place the brush in household general waste. The pole's stainless steel shaft can usually go to scrap-metal recycling separately.
