Generally I liked it because the result was very good. On terrace tiles, rust from pots, black stains from salts and dirt disappear effortlessly. It’s a good idea to watch a video on YouTube; it leaves nothing behind! I used it on the marble around the railings too, and there you need special care because the liquid also contains hydrochloric acid, so you have to be careful not to let it fall to the floor below and cause damage. I used a brush and spread it over 30 by 20 centimeters; it foamed immediately, removed the black stains, and at the same time I removed that foam with a large sponge that was wet with water so the liquid wouldn’t penetrate too deeply and the marble wouldn’t lose its shine. What I want to recommend is to take all protective measures, meaning plastic gloves, a mask, and glasses for the eyes; above all, our health comes first!

It cleaned galvanized manhole grates very well from plaster and tile adhesive, unfortunately, it also removed the galvanization. The instructions stated not to be used on aluminum while the grates were iron

Very good. Effective for balconies and difficult stubborn dirt on tiles from pots and oils

Very powerful, worth it, cleans rust from the toilet bowl and many other applications, pay attention to the instructions

It is an amazing product, I used it on hygiene items that had stains for years and they wouldn't come off with anything, but with decavil they disappeared immediately!! It can also be used on toilets that have dirt on the bottom, as long as the water comes out from inside.. it works wonders
