There is probably an actual connection for this, but this works too."

Instead of a single straw and lid, she ditched the lid and used a bundle of straws.

“Great for tricky areas,” wrote the inventive cleaner.

“Also great for cars in tight spots and won’t pick up coins etc!”

A coin-safe attachment is probably lego-safe too, a huge deal for parents with tiny builders.

Once again, parents worldwide were wowed at this simple trick.

“I still can’t believe they haven’t made a nozzle yet for window and door tracks!”

Another said, “This is the solution to my life problems!!”

It seems like these simple items have mighty cleaning power and can be a game changer for busy parents.
