I was impressed with how powerful this cleaner is, especially considering how much it can be diluted. You only need a small amount in water, and it still cuts through green algae and built up grime with ease.
I used it on greenhouse glass and uPVC around the house, and the results were excellent. Even at a diluted mix, it lifted dirt quickly and didn’t require much scrubbing. For heavier areas, a slightly stronger mix made short work of stubborn staining.
Because it’s so concentrated, the bottle lasts a long time and offers great value. Strong, effective and easy to use, I’ll definitely be keeping this on hand for future cleaning jobs

I was a little hesitant to try this on my car’s paintwork at first, as it’s parked in the shade over winter and tends to gather a fair bit of green algae in those damp areas. But I needn’t have worried! I mixed it exactly as directed and applied it using a Hozelock plant sprayer although an empty household spray bottle would do the job just as well.
After leaving it for just a minute, I gave the area a quick rinse and was amazed the algae and grime simply slid away from the paint, bumpers, mirrors and even the rubber window seals. I’d suggest testing it minute by minute if you’re dealing with really stubborn buildup, but there’s no need to leave it on long. I can imagine it works even better with a pressure washer.
Overall, I’m seriously impressed. Simple to use, highly effective, and it left everything looking spotless. Top marks for a brilliant product!

This is the latest in a series of products I’ve bought to help remove the green algae from my greenhouse glass and pvc soffit and fascia of the house. This is the first one that actually the job. Sprayed on, waited a minute or two and power hosed off. Took the first lot off with just a sponge and water. But took to the power hose just for speed. Fantastic stuff. Everything looks so clean.

Once mixed up, I followed the instructions on spraying the areas for cleaning my caravan. After leaving it to soak in, the muck came straight off with a soft house brush. The caravan is now very clean and shiny now. Loads of fluid left for future cleaning ventures.
