Pipe cleaners cost a fortune here especially as they only come in small packets. Being a stingy sod I asked a female friend of the wife if she ever buys her kids the Chinese multicoloured ones to play with. Couple of weeks later she presented me with a gift of some. As they're very long I cut them in half so I made double the amount.
They work fine, the only negative being you have to be more gentle when pushing them through as they're not as strong. I sometimes dip them in the rum I drink which makes them do an even better job.
It has to be said I'm not fastidious when it comes to pipe cleaning.
