THRIFT T-600 Alkaline Based 6 lb. Granular Drain Cleaner by Thrift

THRIFT is the best stuff to clean drains, period. Old fashioned. Simple. Powerful.Don't breathe the fumes.

This is the best drain cleaner I've ever seen and I've tried many many.

No need for dragon anymore. This stuff works great! Use it at least every 3 months for maintenance. No more standing in water during shower.

Thrift is a great drain cleaner! Delivery was very fast and accurate.

I gave it 1 star for “scent” because you don’t want to smell it! It’s caustic and will burn your throat and nose if you inhale it. My plumber recommended this to me years ago and it has been great. Use it as directed and do not inhale the dry dust when filling the dispenser container or the reaction “fog” when adding the hot water. I wear an N95 mask or make sure I move out of the nearby area quickly. It will kind of “boil” up so funnel should be oversized to contain product and the hot water if you use it for a washing machine drain. Same price as at the plumbing supply store and delivery to my door. Can’t beat that! Just use safely and it’ll keep the drains flowing.

I put a cup of the crystals in the drain, poured in boiling water and opened the window as it bubbled and churned immediately. It was flowing Freely in 2 minutes and I was doing my happy dance. I tried every other drain opener I could find. I will always keep this in my home because it works so quick and so well.

Only thing we know of to use for older clogged drains that won't mess up our septic system. It has a very strong odor. Pour it and back way up or it will burn your nose and eyes. It also is only activated by hot water so you have to get the water hot before you start to use. It seems to help some but I'm not sold it is doing all that much. It also leaves traces of the granular stuff in your sink and on your plate in bottom of sink. I always make sure to scrub it off so it doesn't hurt the finish.

Thrift works better than anything else.
