Thanks to Google Translate (and for all future users):1. Shake bottle2. Rotate top from "lock" to "open".3. Invert bottle and press fully into drain4. Rinse 10-15m with waterCaution: do not use near open flame or heat source.----------Does not say how much to use, but does indicate top can be rinsed and reused, so I'm guessing at least 2 uses. Also says works best with multiple pipes (as in an overflow drain) and that fresh water can be run right away. Obviously, first remove plastic shrink-wrap if there is any on the bottle.OMG this was incredibly easy to use. And weirdly satisfying. It's got a very light orange smell to it but not over powering at all. I used it in a slow tub drain. I could hear it foaming through the pipes and it came up the overflow drain. That used about 1/3 of the bottle. After rinsing, the drain works better than it has the whole time I've owned my house. Lol Absolutely recommend.

Doesn’t work leaves rancid smell after using in sink

Used both in bathroom drain and sink drain worked ok not much came out like videos a little dirt but did smell great - not sure really clean

I am so excited this actually worked, I was very skeptical based on the limited reviews and the fact that there’s so little of this product out there (I live in America where there’s tons of varieties of all types of cleaning products but I’ve never seen a product like this). The overflow drain in my bathroom sink has been disgusting for probably two years—it smells sulfuric from build up. I researched cleaning suggestions and saw a recommendation to buy an enzyme cleaner to pour down there (mind you this was a highly reviewed product, and a more common/popular suggestion). Didn’t work at all. I never got around to trying the home remedy of baking soda and vinegar. Anyways, after seeing this on tik tok I figured why not try it. It was really simple to use, it was written in English at the top to twist the cap to line up the two triangles for “open” and if they aren’t aligned it falls on “lock”. I decided to use the whole bottle in one shot because it took about halfway for it to start coming out the drain hole. Initially I was skeptical because after the whole bottle all the foam I saw mostly seemed white and clean. However when I started wiping it out of the sink with paper towels, I saw chunks of build up so it definitely pushed things out. Once I wiped out most of the foam (it didn’t make sense to flush the gunk immediately back down) I ran some water and used a Q tip to clean the edges of the drain. The nasty smell is 100% gone!!! This is a miracle product and I’ll absolutely order again if more build up occurs.

I was heavily influenced to purchase this sink cleaner based off the satisfying videos of dirt and grime being cleaned out with ease. However, I did not check whether the can would fit under my faucet. Unfortunately it did not. Because of this, the foam did not reach all the way to the drain hole on the other side of my sink. Because of this, I don't know whether the cleaning chemicals actually worked.

A product that was definitely overhyped, but I think I knew that going in, it just looked really cool and I want to try it. It doesn’t really do much but produce a lot of foam.

The media could not be loaded.  Upon reading some of the reviews, I notice there is quit a few saying it doesn't work for them. Since I was able to read it was fairly easy to use and it worked better then I expected. It has a pleasant citrus smell and it did a great job pushing out some gunk from the drain hole. Overall 5 starsFor those that need help:Step 1: shake the canister until you cannot feel the liquid inside is moving while keeping the cap in the Lock positionStep 2: turn the cap to the Open position and place directly to the sink hole. Then press down and hold it there until empty. You will start to see form coming out of the drain hole.Step 3: let the form dissolve on its own and then rinse with water (it took about 5 minutes for mine to dissolved)Step 4: there is no Step 4, you are done.

It was horrible. Didn’t do anything. A big waste of money. I wouldn’t allow this product to be sold by Amazon. I can’t find the right words to describe how bad it was.
