Any hobby involving cleaning electrical items will have use at some time for this chemical. It's far better than methylated spirits (which leaves a deposit on your supposedly clean surfaces)and works with very little effort. So, you need only a little at a time to dampen, say, cotton buds.
Try getting this product in the high street - it's impossible. Some dispensing chemists may prodide you a small quantity after asking all sorts of questions. But I have to say this is one of the easiest purchases I've made through Amazon. And a rapid next day delivery. That's what I call good service!
