Review: Drain cleaning - Decloged my shower in no time Review: It works - I really wasn't expecting the liquid to have any effect. Poured it down my very blocked bathroom sink drain and left it for 5 minutes. Turned in the hot tap and "Hey Presto" we have an unblocked sink. Very good value and saved me trying to remove the pedestal to get at the trap. ## Features - Causes severe skin burns and eye damage. - May be corrosive to metals. - Toxic to aquatic life with long lasting effects. - Very toxic to aquatic life with long lasting effects. - Very toxic to aquatic life. - Warning!

Poured it down my very blocked bathroom sink drain and left it for 5 minutes. Turned in the hot tap and "Hey Presto" we have an unblocked sink. Very good value and saved me trying to remove the pedestal to get at the trap. ### ⭐⭐⭐⭐ Used only 1/3 of the bottle and it mostly worked *by U***N on 5 May 2026* Used only 1/3 of the bottle and it mostly worked I bought Mr. Muscle Drain Unblocker. The instructions say to use the whole bottle, but I only used about one-third of it. Even with that smaller amount, it mostly did the job — the drain started flowing much better. I think if I had used the full bottle as recommended, it would have completely cleared the blockage and removed all the grime. Pretty effective product, and you might not always need the full amount for partial results. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/59654042-mr-muscle-drain-unblocker-500ml-heavy-duty-fast-acting-gel](https://www.desertcart.jp/products/59654042-mr-muscle-drain-unblocker-500ml-heavy-duty-fast-acting-gel) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-22*
