Toilet brushes and child safety

[Pamaga]

Does anyone know of a childproof toilet brush? Our grandson loves brushes, making a beeline for any he sees. I have searched the Internet and in shops for something relatively childproof but all the loo brushes I've seen are pretty accessible to curious toddlers. Waiting to see one on Dragon's Den!

I don't allow my children to be in the toilet unattended. I keep the loo door shut and my eldest goes in, goes to the loo and comes out.

If you are concerned try the duck fresh brush, nothing that has cleansing products on is left behind.

put it on the window sill when he visits?
