What’s the difference between Drano® Liquid Clog Removers and Drano® Max Build-Up Remover?
Drano® Liquid Clog Removers can unclog a drain fast. They contain chemicals that quickly dissolve hair, soap scum and gunk. You can use Drano® Liquid Clog Removers to unclog a kitchen sink, bathroom sink, shower or clogged bathtub, but DON'T use them in toilets. For clogged or slow-running drains, apply the product and let it work 15 minutes. For tough problems, allow 30 minutes.

Drano® Max Build-Up Remover works over a longer time period to prevent build-up in pipes. Used regularly, it can help keep your drains flowing freely. It contains helpful microorganisms that release enzymes to break down residue.

For preventive drain cleaning, you can use Drano® Max Build-Up Remover in drains, toilets and even septic systems. But you must give the microorganisms time to grow along the drain line and clean it as they go. Apply Drano® Max Build-Up Remover overnight or before you go to work. Then wait 6 to 8 hours before running water down treated drains or flushing treated toilets.

I have a slow-running toilet. What Drano® product can I use to get it running freely again?

I have a slow-running toilet. What Drano® product can I use to get it running freely again?
The only Drano® product recommended for use in a slow toilet is Drano® Max Build-Up Remover. When used according to label directions, the microorganisms in this product will break down toilet paper and organic matter in pipes, which can slow water flow. (This product will NOT open a completely clogged toilet.)

Do not use any other Drano® product in toilets. Drano® Kitchen Crystals Clog Remover generates heat that can cause the vitreous china in the toilet bowl to crack. Drano® Liquid Clog Remover and Drano® Max Gel Clog Remover do not contain microorganisms. The trap configuration in toilets prevents the Drano® Liquid Clog Remover and Drano® Max Gel Clog Remover from reaching areas where matter can accumulate and cause plumbing problems—so these products are ineffective in toilets.

The Drano® Snake Plus tool does not fit down my drain—what do I do?

The Drano® Snake Plus tool does not fit down my drain—what do I do?
Drano® Snake Plus was designed to unclog a kitchen sink, bathroom sink, shower, bathtub and even a laundry drain. However, sometimes inserting the tool takes a couple of additional steps.

Often, drain grates and other clog-preventing mechanisms cover the opening of the drain, making it difficult to insert the Snake Plus tool. If you’re working on a clogged shower drain, a tub drain, a kitchen drain or a laundry drain, you may encounter a drain grate. Simply remove the grate using a screwdriver and then insert the Snake Plus tool.

If your drain has a stopper, try rotating the stopper, then remove it using an up-and-out pulling motion. Occasionally, the stopper will be attached to the pipe in which case you’ll need to go under the sink and remove the screw or bolt from the vertical shaft. Then pull the rod out from the pipe and finally pull the stopper out of the sink.

If you’re having difficulty maneuvering a drain with a shallow vertical pipe, such as a bathtub, you may have difficulty fully inserting the tool. Try angling the tool away from you while inserting and slowly work past the bend in the pipe.

Why do I need to use the Drano® Snake Plus tool first, before using the concentrated gel?
Sometimes drains are too clogged to be treated with just a gel alone—that’s why we integrated the Snake Plus tool. By manually loosening the clog in the pipe with the tool first, the concentrated gel can then power through and completely unclog the drain (even the most stubborn ones).

Can I reuse the Snake Plus Tool?
No. After you unclog the drain, the Snake Plus wand (and the clog remnants) should be promptly thrown away for both sanitary and safety reasons.

Is it normal for a few of the Snake Plus tool barbs to break off during use?
Yes. It’s totally fine if some of the barbs break off while you unclog the sink or drain. They will not make the clog worse, nor will they damage your pipes. Any rogue barbs will be flushed away by the concentrated gel.
