  1. Hello
    I have discovered at the back of a cupboard 2 big boxes of 250ml glass bottles .All are stained and I assume hidden by my work shy predecessor. As I am short of these does anyone have any generic cleaning tips .
    much appreciated

  4. An excellent starting point is the Decon range.. Be prepared to wear sun glasses to avoid the glare.:D:D

  6. I'd try the dishwasher- I use liquid detergent in mine and then any stubborn stains I'd try 2M HCl as Shannon said :)

  7. We've had great results using non-bio washing powder directly into the beakers to soak for a day or so

  8. I do apologise for the dodgy spelling Beth - it's my keyboard (he says lying)!:D:D:D
     
  9. But which one do you start with?

    Tempted to get a bottle of the decon 90 for physics for when they play with their radioactives :D

  14. Beth, I think that you too may be joking around - my posts invariably have a dodgy spelling mistake. I have to say that it's all down to my keyboard.:D:D:D
