CONS: Not cheap at around 50p a wipe. Wipes aren't huge either.
The sooner bird lime is removed the better for your paint, and this box containing ten individually wrapped wipes is a conveniently rapid method.
How long they last will depend on your luck, if you park under trees or your proximity to the seaside. The wipes are decently moist, and best rested on the offending area for a minute to soak in. Ideally the muck should be removed in a pinching movement rather than being scrubbed back and forth, which could just end up making life worse for your paint work.
The wipes aren't huge and I ended up wishing I'd had a rubber glove to hand as a result. Hot weather that bakes the bird's ablutions on to the paint may prove too tough for these simple wipes.
TIP: Some detailing spray and a pack of soft tissues might work out cheaper in the long run.
