French version of Drano works like a charm

My washbasin was not draining properly (probably because of a half year's worth of hairballs and undissolved soap trapped in the pipes), and so on the advice of my classmates, I bought the French equivalent of Drano.

I poured half of it into the pipes (it reeked of bleach!) and let it burn its way through the pipes until the next day. The next day when I turned on the water to test it -- whoosh! the water flowed down the narrow drain as if it had never been clogged.

Funny how inexpensive some solutions can be. Remember the clogged shower drain? A 2 Euro plunger solved it. This Drano equivalent? 0,52 EUR. Less than a dollar. What a great value for piece of mind.
