Works well for the shower drain I had to use it on. I am not sure if it was hair or grease blocking it.

I was pleasantly surprised at how well Drano worked. It was also easier to handle for me and takes up less storage space than my previous brand.

We had standing water in the shower. poured the Drano in overnight and in the morning it was gone. Works great.

Put 3/4 of a bottle down the bathroom drain for the bathtub within 25 minutes it was nice and clear it was running real slow

This stuff is so handy when you need it. I bought the dual pack just to stay ahead of that occasional necessity.

These bottles were delivered in excellent condition. This large size is really good as I cn get multiple uses out of one bottle.

Effective eventually. I don't think it works as well as it used to. It seems like I have to use more of the product to move the clog.

Haven’t used it yet but the last liquid Plummer sams had worked very well so I am expecting the same from this one

Excellent Drain Cleaner. After using two other brands with no success this Drank did a very good job.

Excellent for shower drain hair clog preventative maintenance; and in any drain that has a potential for blockage from routine use.
