Can I use Stain Remover with septic and greywater systems?Updated 5 hours ago
TL;DR: Yes. Stain Remover is suitable for septic tanks and greywater systems when used as directed. The enzyme-based formula is phosphate-free and biodegradable. Stick to normal doses and follow any local reuse guidelines.

Why is it septic and greywater friendly?
✓ Why it works
✓ Enzyme-powered cleaning that breaks down stains biologically rather than through harsh oxidisers
✓ Phosphate-free, chlorine-free, and bleach-free: none of the classic greywater troublemakers
✓ Used as a pre-treatment spray, so only small amounts reach the outflow per wash
✓ Readily biodegradable surfactants that break down without accumulating in the system
How do I use it with my system?
✓ Normal use
Spray the stain with Stain Remover, wait 5 to 10 minutes, then wash as usual on a full rinse cycle. Use only what you need. Overdosing increases surfactants in the outflow without improving results.
✓ Disposal
It's best to use up leftover product on laundry jobs rather than disposing of it. If disposal is necessary, dilute 1:10 with water and pour down the sink while the tap runs. Greywater reuse rules vary by area and provider, so check local guidance if unsure.
✓ Good to know
✓ Always follow garment care labels and your machine's instructions
✓ If you have a specialised treatment setup, ask your service provider for any extra guidance
✓ Works with both ducted and wicking-bed greywater systems at normal household use levels
