Oatey 20410 Hercules Glug Crystals Drain Opener, 20 oz (Pack of 3)

Works every time the drain seems slow. Recommended by a plumber and has quickly become the only product we will use to clear clogs, blockages and slow drains. Plus it makes a quiet (but very satisfying) whoosh as it clears.

This product never fails to clear up my slow drains. That said, keep your face far away from it when you are using the product. I accidentally inhaled some of the dust when I was pouring it down the drain, and had a bad coughing fit. Who knows what chemicals I ingested. Now I wear a mask when i am using this product, and all seems well. My plumber suggested I used this because of how well it works, and how safe it is on pipes.

Works good for drain open

this stuff was recommend by our plumber and it does the job and does not hurt the pipes. we had a clog in our toilet we plunged to no avail I had to put it down 2 times cause there was some movement thank goodness it took a while but it cleared the clog. soon as we see we have a slow drain we put it down and works every time. Great stuff

A professional plumber recommended this product at our last services call. We consistently get clogs because our home builder tied our HVAC drain into our sink line. Anyway. Half a bottle of Glug and some Hot water cleared the clog. The 3 bottle we got were the best value on Amazon hands down. Only wish it arrived sooner. Would totally order from this merchant again.

Fast and easy. Takes minutes to work, vs others that take 30+. A plumber told me about it. No snaking or digging for gross hair clogs. Buy a 3- pack since each unclogging takes about 6oz.

This drain cleaner will eat through any clog.Just make sure you use as hot of water as you can.

My daddy swore by this and now so do I. We have a kitchen sink drain that runs slow (house is over 65 years old) and using this keeps the pipes running better! I use monthly to prevent any slow moving or clogs.
