Which cleaning product does not harm reptiles?

After recommendations over 25 years ago by my local reptile vet and a number of reptile shop - I have used a dilute solution of Milton Fluid (the stuff you sterilise baby bottles with). ONE cap to TWO GALLONS of water will do the trick. Remember to rinse the vivarium thoroughly with clean water afterwards.

I also use the same solution to soak new cage 'furniture' before use - leaving it to dry overnight.
