The loo cleaner tablets make an unpleasant house task so easy. Just drop a tablet in the toilet bowl and return after 15- 20 minutes and watch it froth up as you clean it with the loo brush. Combine the job with koh universal cleaner and the grout brush to get into the awkward corners and it's 'job done' in a couple of minutes. You end up with a sparkling toilet. ( pity it doesn't get seen by too many people!)
