Everbuild 401 High Strength Brick and Patio Cleaner, 5 Litre

I would encourage anyone to buy this product. We removed an old shed, and underneath the flags were in good shape but covered in cement stains. Some parts the cement was quite thick. Within an hour it had all lifted, you could here it sizzling. Didn't even have to scub, just rinsed with cold water. It looks amazing.

Very good product does a very good job at cleaning up the flag stones would buy again and good seller

Very strong powerful & did the job perfectly. It’s important to be safe in using it as it’s dangerous in the wrong hands (especially children). Wear the appropriate clothing & gloves for such an acid.

Fantastic product, does exactly what it should with ease, will definitely buy more of this.

It works fine on some of the patio but not other slabs , the red ones it did not even touch the green algae

A good strong cleaner easy to use on my pressure washer. For what it does it's good value. Removes moss, stains and mold easily

After rain and using a too wet mix of mortar for repointing my patio, this ready to use brick acid worked perfectly to remove cement stains from Indian sandstone patio slabs. Wetted, then used a stiff natural bristled scrubbing brush to remove cement stains that were a few days old. Rinsed off patio after 20 minutes. No staining to the sandstoneWent on to clean wall bricks with green algae. Good price and next day delivery, excellent

Good price for what it does, excellent at pre cleaning driveway before pressure washer
