I've been using Wilko Bruclens for absolutely everything, and it's been great. However, it does require that the water be warm, in order to dissolve and do its work. I just wonder, is there a similar product to Bruclens which doesn't require warm water? I mean, it's not a huge deal to mix a kettle full of hot water with cold water from the tap to use Bruclens, but it would be even easier if there were something that could be used cold, for bits and pieces like PET bottles, airlocks, rubber bungs, etc. Anyone know of a product that fits the bill? I saw this guy on Youtube who used a handheld spray-on steriliser, which he simply sprayed on cold and then rinsed away. Any ideas? Thanks
