I've got a very slow emptying sink. I've removed as much visible gunk from straight pipes and elbows in areas I can access but it's still not 100%
Is there a drain cleaning solution you can recommend that will clean the inaccessible pipework and joints or should I try one of the flexible corkscrew drain cleaners available from most places?
