Excellent chemical to be used with great care. Does exactly what it was purchased for - to remove Rust Stains/Marks from Paving Mono Blocks. Care should be taken to use the correct dilution, pouring the correct amount of Acid into a measured amount of water. Essential to use Face protection, Mask and Goggles and Rubber gloves. After 5-10 minutes the Rust Marks slowly disappeared. A second application was used to remove the rust marks completely. Safe storage is absolutely essential. Will purchase again from this supplier. Packaging and delivery were excellent.

Using to Clean rust from a neglected Motorcycle , used 5parts Deionised Water to 1part Hydrochloric Acid , 10minutes soaking different components including rear sprocket & rear shocks , Rust & Dirt was removed & my indicator bracket was had its paint stripped to bare metal (I reitterate , this was within 10mins of a dilluted soak) , make sure you have something to treat the acid , I used Sodium BiCarbonate & Deionised water to neturalise the acid before drying and instantaneously applying WD40 until my Por15 Rust treatment arrives. Phosphoric Acid may have been a better use as it etches the metal with a phosphorus overcoat , this eats the metal & if left too long will speed rust in front of your eyes E X C E L L E N T P R O D U C T

Purchased this to clean a cement mixer and some paving. I have already cleaned the mixer and this did an incredible job. Mixed at a ratio of 10:1 with water it fizzed away all of the built up cement in about 10 minutes. I would encourage people to undertake this sort of activity outdoors well away from anyone else, especially children. The gas given off by this process is corrosive and can damage your lungs, this product needs to be handled with extreme care. I haven't cleaned the paving yet as I need to work out how to apply the diluted acid to the paving without damaging the surrounding vegetation but if the mixer was anything to go by, it will do a great job.

I used it to clean both my garden paths, the lower brickwork of my house and it all came up like a treat, the paving slabs look almost like new. I will be buying some more but a lesser strength to keep both pathways and brickwork well maintained, I still have some of the original left and that will be helpful to clear stubborn moss that appears after a long winter. I recommend this product to everyone, it makes light work of cleaning paths, brickwork and paving slabs.

Wanted to descale the toilet pan, calcium had built up round the bend, inaccessible to mechanical removal. We used half of the container,a bit each day and it has dissolved all the rough covering, and is just like a new pan. Thank you very much
