Review: Got to use it right - Fantastic product β€” but there’s a trick that makes all the difference, and honestly it should be on the instructions. Use warm water at around body temperature, drop the tablets in, and mix until you get a brown liquid. Let it sit for about 5 minutes, give it one last stir, then pour it slowly down the drain to coat the pipes. Leave it overnight. The warmth is key β€” it activates the bacteria. Boiling water kills it, and cold water makes it sluggish, so that sweet spot really matters. If the first round doesn’t fully clear it, repeat. I started with 2 tablets each time and now just use 1. Note: it can take up to 48 hours to fully work. Once you get the method right, it really delivers. Review: So far so good - Like most on here, I had an drainage issue from my treatment plant. I had it emptied the day after I realised it was nearly overflowing and was advised I would need a new drainage field / soak away. With the cost being Β£1000+, I went looking for other solutions as the install was only 3-4 years ago. I purchased these and took a stab in the dark the blockage was caused by grease. Upon first use I used 3 tablets devolved and poured 1 directly in the tank and the others as instructed. The next day there was no change and the level was slowly rising up again. I then purchased some drainage rods and rodded the outlet pipe. That also seemed to make very little difference. I added more FOG tablets direct to the tank. The next morning the level had started to go down! Slowly but going down at least. Day 4, the tank was back to normal level . My opinion is that the combination of the two allowed the speedy results seen. I will.be keeping up with the treatment going forward. ## Features - Effective Drain Odour Remover & Unblocker – Envii FOG Klear contains billions of beneficial bacteria & enzymes chosen specifically to digest build ups of fat, oils & grease, whilst effectively cleaning smelly drains - Ideal for Septic Tanks, Kitchens & More – Our septic tank unblocker can also be used in kitchens, outdoor drains & drain fields where blockages made up from fats, oils and grease are present - Strong & Natural – Due to each tablet containing billions of beneficial bacteria & enzymes, FOG Klear is a fast acting grease remover.

Im living in the apartment and kitchen sink gives me a headache from time to time** A: Yes, fill the sink with warm water, dissolve 1 or 2 tablets, leave for 30 mins, stir water and the slowly let water out of sink to allow bacteria contact time **Q: How many tablets in a pack please?** A: Never actually counted them, but it says '12 months supply' in the Amazon site product description (presumably based on one sink or other outlet) and the pack says use monthly, so I'd say 12. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Got to use it right *by P***U on 2 April 2026* Fantastic product β€” but there’s a trick that makes all the difference, and honestly it should be on the instructions.
