“I just noticed that there are tons of tiny metal balls under my kitchen sink. Most are not perfect spheres but almost all of them are round. They do not dissolve, and some look like they’re rusty so I think they’re made of metal. Above this cabinet there is a kitchen sink with a disposal and dishwasher. They have appeared in the past year or so, since I thoroughly cleaned under the sink when moving in. What are these?”

You’re cleaning under the sink, reach behind the pipes, and suddenly feel something strange — a handful of tiny metal balls, some shiny, some slightly rusty. You didn’t leave them there. You don’t own tiny metal balls.
So where did they come from?
Don’t panic — this isn’t a sign of sabotage or a hidden science experiment gone wrong. In most cases, those little metal beads have a very logical (and common) explanation: your pull-out kitchen faucet.
Let’s solve the mystery.
 The Real Culprit: Your Faucet’s Retractable Hose Weight

 How It Happens

Over time, due to:

Constant pulling and retracting

Water exposure

General wear and tear

… the plastic or rubber casing around the weight can crack, split, or degrade.

Once the casing breaks open, the metal balls spill out and roll to the bottom of your cabinet — hence the surprise discovery during cleanup.

 Signs this is the issue:

You have a pull-out
