At one time or another we all have had to deal with problems with our sinks, whether in the kitchen or in the bathroom. With Foaming Liquid Plumr it clears tough clogged drains and pipes. They can be either slow running or fully clogged and the foaming pipe snake, will remove the problem. With the professional strength all you need to do is just pour entire bottle contents (1 pt) down the drain and wait a hour, then run hot water to flush through. It is not recommended for use with a plunger or in your toilets. Liquid Plumr is safe for all pipes. As with any cleaner there is a danger if it comes in contact with the eyes or body, or is swallowed. Keep out of reach of children., even though there is a safety cap on it.
I always keep this on hand and find it to do a great job. Of all the products for this kind of job, this is on the top of my list. I highly recommend it, if you have never tried before.
