Jarder Avis 

Extremely easy to use as no measuring & dilution required. Killed all green moss on my driveway. Left a slight white residue for 24 hours but this soon disappeared and my drive remains moss free a month later. Great value also. Would highly recommend

We had great results with the Indian sandstone cleaner. Next day delivery really kept the project going when we ran out. Thank you.

Great product did exactly what what needed to finish the job
Why no screws

Good product and competitively priced. Cleared the problem without issue.

I have purchased this product for a number of years now. It does what it says on the tin. Always clears moss algae and staining from my drive ,patios and paths. Can highly recommend its efficacy. Would recommend ordering direct from Jarder. pricing is excellent and delivery is very quick with full notification on order processing and delivery. The chap who delivered mine Second time by the way is very friendly polite and accommodating at where to drop my package. I always buy 4 bottle pack. For me that provides a great price and adequate for my needs. Have recommended this to a few neighbours because it is so good .All in all a very positive experience

Not a product I would recommend , have applied it twice since purchase and the weeds are still not dead.

The black spot cleaner was brilliant, it was like a new patio after I had done it. I only wish we took photos before and after to prove how good it is. I would definitely recommend it. It was fast efficient service too.

The delivery from Jarder was very timely. Having tried several other brands that claim to get rid of black spot that didn’t touch it, I was skeptical, but had read good reviews so gave it a try. It has a very strong bleach smell but I could literally see it working before my eyes. I would recommend buying more than you think you need as I found the two bottles I had not quite enough to do my whole patio and path although the square metre size was within the suggested metre square coverage. I am really pleased with the results and would definitely recommend. My sandstone pavers now have their colour back and most of the black spot has gone. Definitely the best product I have tried.

We tried Jarder on three second hand sandstone pots. These items are extremely heavy and architectural - quite lovely, but had been severely weathered when we got them. They were actually grey and sold as concrete pots.
We bought Jarder Sandstone Cleaner and used it on all three, the instructions were clear, and the results were amazing! The cleaner removed all the black spots, the lichen and the stains. The grain in the sandstone saw the light of day for the first time in years and they look beautiful. Thanks Jarder for sending the items so fast, and for the excellent results! Fabulous product!

The patio Black Spot Remover is an excellent product that I have used for many years and would highly recommend.

Jarder spray and leave - such a great product! I’ve been using it for many years, I have a white rendered contemporary property and a drive area with Cotswold buff stone (white), areas of the walls go green (October/November) as I have trees in close proximity, I spray the jarder onto the walls and within a day or two the walls are back to the original colour - the same applies to the stone. So easy to use - Mike

I have not yet used the roof moss remover but am sure it will be perfect

Great result, made a old patio look new.

Not used it yet! But I’m sure it’ll do the job.

We have bought from Jarder previously and their folding sun loungers are very practical and comfortable. We therefore decided to order replacements from them this summer and have not been disappointed. The quality of these sun loungers is again very good and should be long lasting.

Delivery supposed to come for few days every single time they said that nobody was home they left the card but they didn't driver was totally in diffrent area
Had delays at my job be ause missing product
Poor service

I have used Jarder spray and leave patio cleaner for a number of years now , its a great very effective product . Next day delivery has never failed and excellent mutli buy price.

Swift reply to query with equally swift delivery

Good and print delivery. But I can’t review if it works or not because I have only just sprayed it in the grass

Excellent service to match excellent product.
