I did it a couple of weeks ago, i used it neat but with a ball of steel wool, so it's abrasive but won't scratch the pipes at all. It's a very effective treatment, just clean any crud of the pipes first, then apply and leave on for 20-30mins before hosing off.
Seriously though, use 2 pairs of rubber gloves, and wear eye protection of some sort. Get that stuff in your eye, and you'll really regret it.
