Jarder Avis 467

Ordered 4 x 5 litre XL Black Spot Remover. Very good value for money with free delivery. Have today used the cleaner on the indian stone flags on my patio, which was laid approx. 14 years' ago and almost all the flags were completed covered in black spots. I can't believe how gorgeous the flags are now they've been cleaned with this product. I was hoping for some improvement but the flags have turned out way above my expectations. The original colours can now be seen and look absolutely fantastic!! I am totally impressed and overjoyed. Would certainly recommend using this product and Company again.

Absorbed really well leaving a great result

product delivered on time and worked well on my drive

Easy to order and fast delivery

I had neglected the patio [Indian Sandsrone] for a couple of years and it was rather dirty. The Black Spot remover worked a treat

This cleaner is excellent. I could not believe how well it took all the stains and spots off the Indian stone. A really excellent product that does what it says on the container.

I have not had any contact with the seller or courier about my purchase.

The delivery company delivered parcel to wrong address, when I rang Jarder customer service the person I spoke to was exceptionally pleasant, dealt with the issue promptly and said to call back if still had an issue. The ordering process was easy I will definitely be ordering from this company in the future.

I used the sandstone cleaner for the first time . I am more than impressed. My patio looks like it has just been laid . I am absolutely thrilled with the result.
I would definitely recommend this to anyone.

When ordered was informed that it would be delivered the next day ordered on the7 / /4/26
Was text by DX parcel service that my item would be delivered on the 08/04 later received a text from DX stating that they were unable to deliver stating that they would retry (indicating that DX had tried to deliever I or my partner were in I also have a ring doorbell there was no evidence of DX approaching my door .DX sent similar texts for the next 2days without any explanation
I also spoke to Jarder outlining the problem I expected a call back I had to contact Jarder however the issue was not resolved

Amazing product. Works like magic before your eyes. After struggling for years to clean my patio with a water jet, I've finally found something that really does the job. When I look through my window I still can't quite believe that my terrace looks virtually as bright as new.

Everything fine, block paving cleaner work well

Fast, efficient and trouble free service. Package arrived in good shape in in timely fashion. The driver even lifted and place the package into my hallway.

Fast, efficient service. Excellent product.

Fast reliable service ..with a great product
My patio looks ‘good as new’.

I had cause to phone Jarder and received first class assistance from the person I spoke to (Jade). Jarder is a very good effective product

Ordering was easy. Delivery time was good. Product was easy to use.

The order was dealt with very promptly. I have used the product today (April 8th 2026). It's early days but I am optimistic. Our patio has been down for at least forty years and was heavily infiltrated with moss and both black and white lichens. It's already a different colour and I am hopeful that once it rains it will look a great deal better. Maybe best not to do the job on the hottest day of the year though!

I ordered my Black Spot Remover from Jarder as their price was the same as other suppliers. I ordered on Friday morning and my order was delivered the following day.
So far I have used one 5L tub of of the four I ordered and I am 100% satisfied with the result. The coverage was also as it said on the tub ie 40sq.m.

Brought the colour back to my Indian sandstone patio but a little disappointing that it didn't remove the black spot as advertised, even after 50ltrs!
Very easy to purchase and delivery excellent.
