I find it annoying when my little one’s favourite bath toy gets water stuck inside and turns black. It’s awful! Here’s a tip to stop water getting in or prevent black slime slipping out!
I use some glue to bung up the hole! Unfortunately, it does stop any squirting of water from the toys but with the expensive toys I feel it’s better to stop squirting than to have black slime in the bath water! I have also used a small bottle brush to remove the slime – this works ok as long as you have the time to do it!
