If babies are human petri dishes, then dirty strollers are the plague.

Clean up your Bugaboo’s act with BuggyLove organic cleaning solutions, designed specifically for strollers.

The brainchild of an NYC mom who’d had enough of her fancy baby carriage looking like a frat house on Sunday morning, the collection includes a polish for demucking the frame, a solution for removing stains from the seat, a rose-hip spritz to make everything smell new, and a chemical-free lubricant that silences squeaky wheels.

All the ingredients are natural, so there’s no need to press the panic button if baby snacks on her shoulder strap.

And we think that’s ride on.

Available online at buggylove.com, $50.
