Robparkersbest Avis 

Purchased this to clean up heavy cement staining on my indian stone flags. Was aware that acid based products would damage the surface of the flags. Recommended by a friend to try Conclear, and it did a fantastic job of removing the staining quickly and easily. An excellent product.

Great stuff, rust gone not sure if it will return as only just worked on it but 5 days down the line not returned yet !!

3rd time I've used Rob Parkers Best and never been disappointed

Quick delivery.
Bought Conclear to clean excess cement off natural slate flags.
Pleased with the results, would recommend

Product arrived quickly and has worked miracles on our algae stained patio.

Amazing product. My grey Indian sandstone had just be laid and the builder tried to get some stains off it with brick acid. The patio suddenly overnight had brown and orange patches on the areas he had used the brick acid. I was so stressed as it had cost a lot of money and looked awful. Luckily, your rust remover removed them all and it looks like new. Absolutely delighted, thank you

An excellent product which restored our patio perfectly. Great prompt delivery service.

Didn’t really work, a very expense product for such poor results.

Cleaned the cement off sandstone flags and left a beautiful finish

Removed rust marks from grey sandstone.

I had been assured that this could not be done by other stone 'experts' but Rob Parker said it could and it worked

Didn’t fetch any of the iron stains out despite several applications and followed all instructions on the bottle.

I work for a Livery Hall in London. We have a SERIOUS issue with algae on our yorkstone courtyard. Not anymore we dont. Ill be reordering a larger batch very soon. The small test area we used the algae inhibitor on is just a revalation! The best product ive used commercially!

Product was excellent in getting marks out of kandla grey paving caused by brick acid. Genuinely like new!

Recently used the algae remover, a very good product. But please be VERY AWARE it IS VERY HARMFUL to animals and this is not mentioned on the container or the discription leaflet. We have 2 VERY ILL CATS, even though our vet has wrote a letter stating that the product was the cause for our cats to be ill, rob parkers chemist simply rejects this. Very DISSATISFIED with the follow up.

Excellent service - arrived very promptly despite the lockdown. Last year I bought the Algae remover which was very effective, and this year the Patio Cleaner. Will definitely continue to use them.

Excellent product. I put it on my Indian stone patio that had a lot of green algae, as per the instructions and it cleared it within two days. Would certainly recommend. The price of the delivery was a bit steep but the results make it worth while.

I was disappointed when I read that the 250ml contents will only make 4 litres of liquid to spray the patio - I will need at least x 4 that amount to spray just my back garden patio areas - without starting on the front drives..... makes it very expensive....
Maybe I didn't read the advert properly - or it didn't make clear that it only provides 4 litres

I purchased this product to clean my patio which is north facing and very green and slippery. unfortunately because of the inclement weather I have been unable to use it yet. I have high expectations that it will do the job.
