    I use an old toothbrush to clean the inside of my glasses, the bit that rests on your nose, it’s just like new when it’s done, very grubby if you don’t.

    Thanks for your kind words about my poems – I really love yours, too. Here’s another bit of silly doggerel!!
    My bike was really playing up, the wheels were jammed and stuck,
    and then I read this good advice, what a piece of luck!
    So I applied the tooth brush, making sure to look,
    and see it penetrated in every little nook,
    I was so proud of what I’d done – think of my falling heart,
    when I found out with a groan it STILL wouldn’t start!
    So I went to the repair man, and asked for his advice,
    he looked it over once, he looked it over twice,
    then said, ‘The good news or the bad?’ So, fearing the worst
    I said he’d better give me the piece of bad news first …
    He said, ‘Your wheel is past repair, I cannot coax it back –
    But here’s the good news – there is not a single hint of plaque!

    Great article, but PLEASE don’t use an old, used toothbrush in your fish tank! You shouldn’t put any contaminants into a fish tank (toothbrush would have toothpaste and old saliva on it, at least!) as it can mess up the delicate chemical balance in the tank and, worst case scenario, kill your fish!
    Not even ok if you scrub the toothbrush first with cleaning agents like soap or washing up liquid as those chemicals can mess up the tank too. Best to just not do it at all!

    I’ve been using an old toothbrush to clean round my taps for years now. I only wish I’d take it with me when using the facilities in restaurants etc. When I cleaned for an army colonel’s wife she cleaned the springs of their beds before they went to a different place. It was called a march out and everything had to be spotless for the next person to move into.

    1. 19 Collette J Reply

      Haha Sheena, yes they may not be 100% clean at restaurants. That’s very interesting about the bed springs, thanks for sharing! 🙂

    I always save my old tooth brush when i’ve replaced it. The old tooth brush is ideal for cleaning the shower hose and under the shower door and inside the water taps around the house.

    Brill tips. For ages, I’ve use an old toothbrush to clean inside the toilet. It’s great for cleaning under the rim, around the water line, and below the water. But I will buy some cheap toothbrushes to use around the home too. Thanks. XXX

    I have two beautiful big old cut glass flower vases and always use an old toothbrush and spray bleach to clean them with. They absolutely gleam, with the sunlight bouncing off the intricate cut, carved surfaces.

    You CAN use a toothbrush on your fish tank BUT there are a couple of precautions you need to take first.

    Thoroughly rinse your toothbrush then let it stand for an hour or so in a water conditioner like Tapsafe (other products are available!), finally, draw off a little water from the fish tank and rinse the toothbrush in that too, finally, keep that toothbrush to one side and use it ONLY for cleaning your fish tank.

    A bit of a laborious procedure, so you may not find it too worthwhile.

    Also, don’t forget that you can use an old toothbrush to clean around hard to reach areas on your cooker, such as along the edges and around the control knobs, for added cleaning, dip the toothbrush in a little white vinegar or use a hob conditioning paste.
