Review: Powerful Cleaner – Brilliant Results with SH Mix - This is my go-to for patio and driveway cleaning. I use it mixed with water and a surfactant in a jerry can, and it performs extremely well with my pressure washing setup. Black spots, algae, and grime come off fast, and you start seeing results in under 10 minutes. Pros: • Very strong SH mix (14–15%) that works quickly • Great value at under £18 for 10L • Ideal for concrete, tiles, and stone • Pairs perfectly with surfactant and water for pre-treatment Cons: • Strong chlorine smell (normal for SH) • Will bleach fabric and sensitive surfaces—use PPE Verdict: Excellent for exterior pressure washing pre-treatments. Results speak for themselves.
Review: Excellent option to pressure washing - Excellent kit, I get three 10l watering cans out of a 5l container, so roughly 30% Juice to 70% water. Great for cleaning slabs and mono bloc driveways a very good option to pressure washing which erodes your brick/slabs. It also blooters weeds into oblivion. I also use a similar mix and spray my house walls as I live right next door to bonded ware houses which produce Whiskey Black, this stuff turns my nice dark brown brick a manky black colour.. simply mix and pour..

### ⭐⭐⭐⭐ Very Effective on sandstone patio
*by R***B on 18 August 2023*

Using a chlorine solution is known as "Soft Washing". Called this because high pressure blasting isn't necessary to get an amazing visual difference in a short time. Two areas of Indian sandstone patio were looking a mess, I thought that most in the more shaded area would need to be replaced! Sandstone is soft and porous by nature, algae and lichen love the stuff. Sandstone is vulnerable to erosion, using a Karcher dirt blaster lance started to cause pitting in some of the softest areas of individual slabs and I was looking for a better way to defeat algae, Lichen etc. I knew that after a general wash down, bleach was the tool, but the domestic thin bleach is just 2% w/v of sodium hypochlorite (Hypo), which didn't work, even applied neat and left to soak. This Hypo is 15% when new, I made a solution with 50% tap water, sprayed it on the slabs and quickly noticed areas of small bubbles as organic residues were oxidised. After sufficient dwell time, it was rinsed well with a hosepipe. There was an amazing initial effect and for a few hours after rinsing, the slabs appeared to be getting cleaner still! It didn't cause any chemical staining of the sandstone and hard scrubbing was not necessary. Some of the more heavily affected areas had a slight visible residue of dead organic stuff! This will lose its grip after a few rain showers, washes and a re-treatment. Value for money lost a point because I purchased two 5L containers, a single larger container would be cheaper by unit, but it was my first trial of this specific product. Ease of use lost some points, only to highlight that it isn't something anyone can apply safely. It MUST be used and handled with great care. PPE should be used, access to areas being treated must be controled, pets must be kept away until it has been rinsed very well. There's much more to safety than these basic points, which aren't a guide. I used a backpack sprayer with an oval "drift guard" surrounding the nozzle, this stopped spray mist from being blown away from where it was being applied.
