Universal Descaler - 25.4 Ounce

This descaler is very effective and cleaned my coffepot, making it look new. I'm a fan!

This is truly a miracle potion. It totally removed several years worth of hard calcium deposit on my electric kettle that could not be even dented by repeated boiling of citric acid or vinegar - and did it in just one hour.

Very impressed. Had a very bad buildup from hard water. It removed about 95% of it. Purchased another bottle to get the rest of it.

Works very quickly, just a couple of rinses and coffee maker is spot on in my experience. This is even using distilled water!

This descaler works very well. It even cleans and brightens my stainless steel sink that I pour out the boiled water/descaler solution when it's done descaling my electric kettle.

Works! But diluted spray doesn’t work as good

This descaler works incredibly well and has become my go-to for keeping kitchen appliances in good shape. I’ve used it on a coffee maker, kettle, and even faucets, and it removes buildup quickly without much effort. Everything runs smoother afterward, and there’s no lingering chemical smell or taste. It’s easy to measure and use, and a little goes a long way, so the bottle lasts quite a while. I also appreciate that it works across different appliances, which makes it more versatile than brand-specific descalers. Powerful, efficient, and reliable—exactly what’s needed for regular maintenance around the house.

This product really works.

Excelente producto contra la cal acumulada

Dieser Entkalker ist der beste von denen die ich bis heute kennen gelernt habe. Es war reiner Zufall, weil ich mir eine neue Kaffeemaschine der Fa. Petra kaufte und diese Firma diesen Entkalker empfahl. Ich bin sehr zufrieden damit, weil er auch die letzten Kalkreste mitnimmt. Er ist nur zu empfehlen.

I’ve tried countless brands available in Singapore and every YouTube hack to remove stubborn stains from my chrome Hansgrohe rain shower and handheld set, but nothing worked as quickly and effectively as Durgol. This product is a game-changer—I’m never going back to any alternatives! I applied it without diluting, and it was so economical to use. Just one application, and the stubborn stains were gone. Highly recommend it!

Magnificent! It removed all scales very quickly without any odour or damage!! Xxx

I bought to descaler my bodum bistro water kettle. Only a little to cover the surface and half an hour later, my kettle is like new!
