CleenU product solution
Enzyme Drain Cleaner
Enzyme maintenance · Pour at bedtime · Private label
Slow drain or a sewer smell? Pour in 50–100 mL at bedtime and leave it overnight; enzymes break down grease, soap scum, and hair on the pipe walls. Once or twice a week, pH-neutral and pipe-friendly. Factory-direct private label.
- Kitchen grease, bathroom soap scum and hair, and food scraps from the dishes coat pipe walls layer by layer. The pipe narrows, draining slows, and the buildup rots into that smell. Caustic openers are for drains already blocked and are hard on skin and older pipes. This is a maintainer that breaks buildup down before it becomes a clog.
- Enzymes need time. Poured in during the day, they're flushed away; overnight, the cleaner sits in the pipe and trap for six to eight hours. Four enzymes cover hair protein, grease, starch, and vegetable fiber, the most common culprits in kitchens and bathrooms.

Before & after
Before and after (illustration)
Before: a full kitchen sink takes a long time to drain and the drain smells sour. After two to three weeks of twice-weekly use, the smell drops noticeably after the first one or two treatments and draining speeds up.
- Before: slow drain, sour smell
- After one or two uses: much less odor
- After two to three weeks: faster draining

How it works
How pipe buildup gets broken down
Pipe deposits mix grease, soap scum (calcium fatty acid salts), hair keratin, starch, and vegetable fiber. Lipase splits grease into fatty acids and glycerol, protease cuts hair and food proteins, and amylase and cellulase handle rice and vegetable scraps, while surfactants help enzymes reach the deposit. The pieces wash away with the next morning's water.
- Pour 50–100 mL at bedtime
- Sits in pipe and trap
- Four enzymes break down buildup
- Works 6–8 hours
- Flushed away next morning

Usage guidance
Use guidance
- At bedtime, pour 50–100 mL (about one cap) into the drain.
- Leave it overnight without running water.
- Use the drain normally in the morning. Repeat once or twice a week, twice for greasy kitchen sinks and long-hair showers.

Before you use it
Important notes

- Not for: Use with acid or caustic drain openers
- Not for: Use with chlorine bleach

Where Enzyme Drain Cleaner stands out
Clear the buildup before it clogs
Kitchen grease, bathroom soap scum and hair, and food scraps from the dishes coat pipe walls layer by layer. The pipe narrows, draining slows, and the buildup rots into that smell. Caustic openers are for drains already blocked and are hard on skin and older pipes. This is a maintainer that breaks buildup down before it becomes a clog.
Why bedtime, why overnight
Enzymes need time. Poured in during the day, they're flushed away; overnight, the cleaner sits in the pipe and trap for six to eight hours. Four enzymes cover hair protein, grease, starch, and vegetable fiber, the most common culprits in kitchens and bathrooms.

Product, use, and procurement
Why is my drain slow and smelly?
Grease, soap scum, hair, and food scraps coat the pipe walls layer by layer, narrowing the pipe, and that buildup rots in place, which is the smell. A weekly enzyme treatment breaks it down before it turns into a clog.
How is it different from a caustic drain opener?
Caustic openers dissolve blockages fast with harsh chemistry; they're for drains that are already blocked and they're rough on skin and older pipes. This is a pH-neutral enzyme product that works slowly and gently, made for routine maintenance and odor control.
Will it clear a fully clogged drain?
No. Enzymes have to reach the buildup to work, and if water won't go down, neither will the cleaner. Snake the drain or call a plumber first, then use this to keep it clear.
What should we decide first for a private-label enzyme drain cleaner?
Three things: kitchen grease or bathroom hair focus (it drives the claims and packaging art), whether to add a measuring cap for a once-a-week routine, and unscented or lightly scented. Positioning it as the gentle, long-term alternative to caustic openers sells better than competing with them.
What are the sample, MOQ, and lead-time terms?
Free samples are usually ready in 3–5 days. Standard MOQ is 500 bottles, and bulk orders are scheduled after packaging and labels are approved.
Product usage questions
Why pour it in at bedtime?
Enzymes need time. Overnight, nobody runs water, so the cleaner sits in the pipe and trap for six to eight hours. Poured in during the day, it gets flushed away before it can work.
How often should I use it?
Once or twice a week. Greasy kitchen sinks and showers with long hair do best with twice a week; once a week is enough for routine care.
Can I use it with bleach or toilet bowl cleaner?
Not at the same time. Chlorine bleach and strong acids deactivate enzymes; wait at least a day after using them.
Can I use it with septic systems and old cast-iron pipes?
It's pH-neutral with no strong acids or caustics, so it can be used on PVC, cast iron, and metal pipes as directed, and at the normal dose in homes on septic systems.
How soon will I notice a difference?
Odor usually drops after one or two treatments. Faster draining takes two to three weeks of regular use while the buildup breaks down.
Can I use it in a kitchen sink drain?
Yes. Pour it at bedtime and the enzymes slowly break down grease and food buildup to cut odor and slow drains.
Can I run water right after pouring?
Best to leave it overnight without water so the enzymes have time to work, then use as normal.
Do enzyme drain cleaners dissolve hair?
No, don't count on it for hair clogs. Hair is mostly keratin, a tough protein that drain enzymes break down very slowly. Pull hair out with a drain hook or by removing the stopper, then use CleenU Enzyme Drain Cleaner on the soap scum and body oils lining the pipe so new hair has less to snag on.
Do enzyme drain cleaners work on grease?
Yes, for the grease film that builds up over time. Enzymes break down fats and food residue coating kitchen pipes, which is why it works best poured in at bedtime and left overnight. A solid grease plug that stops water completely needs a snake or a plumber first.
Will an enzyme drain cleaner help with drain flies?
It helps by breaking down the slimy organic film drain flies breed in, not by killing the flies. Use it overnight once or twice a week for a few weeks, scrub the drain opening with a brush, and keep stoppers and overflows clean. If flies persist, check other drains and floor drains you don't use often.
OEM/ODM customization questions
What can be customized?
All of it: formula direction, scent, fill size (1 L and 32 oz bottles, and more), measuring cap style, label design and language, and ecommerce bundles with drain strainers and hair-removal tools.
Can we test samples first?
Yes, we ship samples first. Use them for two to three weeks on kitchen and bathroom drains that are already slow and smelly, and record odor, time to drain a full basin, and pipe condition. That tells you more than a before-and-after photo.
Which documents can you provide?
We provide SDS/MSDS, a TDS, and batch COAs, plus bilingual label content for your target market. We send them per project when you inquire.
