Pick plastic-free dishwasher tablets
That handy individual wrapper on each tablet is either plastic film or a synthetic PVA layer that doesn't really vanish. Naked tabs, powder or refills clean just as well — minus the wrapping.
Dishwasher tablets feel like the tidy, modern choice — but most hide a small plastic problem. The film around each one is either an obvious wrapper you peel off, or a “dissolvable” coating made of PVA (polyvinyl alcohol). PVA looks like a clever solution because it disappears in the wash, but disappearing isn’t the same as breaking down: a meaningful share passes through water treatment intact and ends up as microplastic in rivers and soil. Multiply that by every load, every week, and the convenience adds up to a steady plastic drip.
The fix is refreshingly low-effort. Unwrapped powder and naked compressed tabs clean every bit as well, and they come in plain cardboard rather than plastic tubs. Many eco brands also drop the phosphates, chlorine and synthetic fragrance that the cheapest all-in-one tablets still carry, so you’re cutting what goes down the drain on two fronts at once.
The one trade-off is that plain tabs and powder sometimes leave salt and rinse aid as separate jobs rather than bundling everything into one tablet. That’s a minute of topping up reservoirs now and then — and honestly, your own salt does more for spotless glasses than any premium wrapped tab. Run the machine full and on eco, and a small swap at reorder time quietly removes a wrapper from every wash for good.
How to do it
- Check what's wrapping your current tabs: a clear film you peel off is plastic; a tablet you drop in 'wrapper and all' is coated in PVA (polyvinyl alcohol), a synthetic film that mostly survives water treatment.
- Switch to genuinely naked options: loose powder, compressed unwrapped tabs, or brands sold in cardboard with no individual film (look for Ecover, Sodasan, Everdrop, Bio-D or refill-shop versions).
- Buy in plain cardboard or bulk from an Unverpackt store, refilling your own tub, rather than plastic tubs and pouches.
- Add a separate rinse aid and dishwasher salt if your tabs are plain — soft results without relying on an all-in-one wrapped tablet.
- Run the machine on eco and only when it's full, so each wash — and each tab — does the most work.
Pro tips & pitfalls
- 'Dissolvable' or 'water-soluble' film usually means PVA — it disperses into the water but isn't reliably broken down by every treatment plant, so it's a plastic worth avoiding, not a free pass.
- Powder lets you dose to how dirty the load actually is — a little less for a light wash — which stretches the box and cuts excess down the drain.
- Hard-water area? Keep the salt reservoir topped up; it does more for spotless glasses than any premium wrapped tablet, and it's cheap.
What it's good for
Good for the planet
- Beats plastic Skips the individual film or PVA wrapper on every single tablet — that's one less bit of plastic per wash, hundreds a year for a typical household.
- Fewer toxins Plant-based and eco-certified powders cut the phosphates, chlorine bleach and synthetic fragrance in some conventional all-in-one tabs.
- Cuts waste Cardboard boxes and refills replace plastic tubs and pouches, and dosing powder yourself avoids the waste of a half-needed tablet.
- Protects nature Fewer dispersed PVA microplastics and gentler ingredients heading down the drain and out toward rivers and the sea.
