Description

With a unique formula containing active enzymes, Drano Max Build-Up Remover helps prevent clogs from forming in your pipes. This product helps remove build up but will not unclog your drain. Use it on a monthly basis to keep your drains running smoothly and prevent clogged drains. An ounce of prevention is worth a pound of cure!

DIRECTIONS FOR USE: Start-Up Treatment For Drains: Run warm water for one minute. Turn off water and pour 10 ounces into drain. Briefly run WARM water again (approximately 2 cups). Avoid running water for 6-8 hours. For Slow-Running Toilets: 1. Flush 4 ounces down toilet for 3 consecutive days. 2. Don’t flush for 6-8 hours after initial treatment. It may be easiest to treat before going to bed or work. On-going Treatment: Pour 2 ounces down each drain and 4 ounces down each toilet every 2-4 weeks. NOTE: Initial use may cause loosened build-up to slow or, in rare cases, block the flow of water. Don’t worry – this means Drano Max Build-Up Remover is working to remove build-up. Simply plunge and repeat the treatment. For best results: Clear pipes of any clogs before start-up treatment with a DRANO Clog Remover. Use as directed. This product will not open clogs. For clogged drains, try DRANO MAX GEL Clog Remover. Do not reuse this package.

Smells nice, works well but takes a long time

[This review was collected as part of a promotion.] First off the smell is very pleasant. I was expecting the typical stinky drain cleaner. This has a very nice fresh smell. Only downside is that you have to wait six to eight hours before you can run water through the drain

Good for toilets, didnt help my slow shower drain

[This review was collected as part of a promotion.] This is a good product for slow draining toilets and can prevent clogs. Easy to use, no strong smell or stain in the bathtub. I thought this would work on my slow draining shower, but it didn’t help my shower problem.

Tough on build up.

[This review was collected as part of a promotion.] Application was super easy, a little warm water and a few ounce of this Drano and my toilet is running smoothly again. It is very effective in unclogging pipes and has a pleasant smell; it does not leave any funky or chemical smell after poured. Highly recommended if you’re looking for something effective and easy to use!

Works well

[This review was collected as part of a promotion.] This Drano is really good. It’s thick enough that I feel like it’s working really well. You do have to wait a couple hours before you can use your drain, but after that time you waited. It really cleared up my problem. I feel like it cleared out all the and hair would recommend it

Overall, a very good product- l definitely recommend it!

[This review was collected as part of a promotion.] This cleaner really does work well for cleaning drains. It wasn’t an instant fix and took a couple of days to fully do its job, but l followed the instructions and the results were great. The packaging was sealed properly and arrived in perfect condition.

Best Drain Maintenance

[This review was collected as part of a promotion.] This was so easy to use and what a blessing to be able to use it on toilets without any splash up. Yes you do need to wait a period of time before you can flush again so you just use it at night rather than during the day for the initial application and then the speed at which the toilet flushes is amazing.

Excellent drain clearer!

[This review was collected as part of a promotion.] I received this drain build up remover from Drano and Influenster in exchange for my honest review. This drain build up remover actually worked quite well to clear my sink. I’ve had a lot of build up and sluggish flow in the drain connected to my garbage disposal and this had my drain functioning like normal again. The garbage disposal doesn’t get used very often which is probably part of the problem and it seizes after a while of not being used. This build up remover got things flowing smoothly again. It worked so well I preemptively used it on my bathroom sink as well and it worked great! Highly recommended for sluggish drains!!

“I had a great experience using Drano FlowGuard Build-up Remover.

[This review was collected as part of a promotion.] Easy to use, effective at cleaning build-up, and a great addition to my cleaning routine. The packaging is convenient and easy to use. The odor is not too strong and as with any cleaning product, is important to follow the safety warnings and directions for best results.

Easy help

[This review was collected as part of a promotion.] Safety is fairly good when used as directed, and the formula is meant for routine drain maintenance rather than harsh unclogging. Its consistency is liquid and easy to pour, packaging is simple and practical, and the result is helping keep drains flowing smoothly. Purity feels good because it uses an enzyme-based formula.

Works great !

[This review was collected as part of a promotion.] I have used this Drano build-up remover before for both my toilet bowls and my kitchen sink and it works great ! It smells amazing it is a thick consistency liquid and I usually pour it in at night once I am done with washing dishes and using the kitchen for the day … it stays overnight and it does its magic in the morning I pour hot boiling water to push any buildups ! I store it under my kitchen sink my kids know to stay away from my cleaning products all of them !

OMG!!! This is a lifesaver

I really thought I'd have to bite the bullet and call a plumber for my half bath toilet in my condo. I knew not to use regular draino and I'd tried everything, snakes, vinegar, everything. One day while strolling my local grocery store I spotted this and had never seen it. Was surprised that it actually said it was safe on toilets so as a last effort I bought it even though it was about twice the price of standard draino. OMG!!! It worked like a charm! First time, I finally saw my take flush fully and I mean this was unbelievable because I have 2 teens and they don't care at all what they do to the plumbing! I would recommend this before paying for a plumber. It's been about a week and we haven't utilized the toilet as we used to because I want to treat it as well as I can before regular usage again but it's doing great. USE AS DIRECTED!!! Pour a bit and flush and let it settle for some hours and do it again but do not utilize the facilities until it's the product has done its job. The longer the better, the more clogged, the longer the treatment. In my opinion, I'd spend $50 on a couple bottles of this instead of a plumber.

Slow-draining kitchen sinks are now free-flowing!

I have a double-sink in the kitchen with a garbage disposal on one side, so there is no way I can use normal caustic drain clog removers. All I could do is occasionally run a ton of hot water Through the disposal with dishwashing liquid In hopes of clearing out anything in the pipes. Draino Max Build-Up Remover to the rescue! I followed the instructions, treated both sinks 3 nights in a row, letting the Draino work overnight before running any water again. I was surprised at how effective it was! My sinks drain quickly, any soap from the disposal doesn't back up in the other sink anymore, and I'll swear the darned disposal smells better (but that may be my imagination). This stuff actually works, and it doesn't take weeks to become effective. I'm totally sold on it. (I received a free sample of Draino Max Build-Up Remover in exchange for this honest review.)
