I bought the Algae Remover and Patio Reviver (Once a year treatment) to remove the green parts on our relatively new patio and retaining wall.

I was not disappointed! This product is amazing! I simply put it into a low pressure sprayer I got on Amazon for cheap and mixed with the stated amount of water. Started spraying onto the green areas and to be honest, I was more hopeful that it would work than believing. But wow, within 4-7 days, ALL the algae had cleared! And now, a month and a half later the patio and wall look beautiful 👌

I will definitely be bookmarking this product to buy again next year 😊 Thank you. If anyone is trying to clean up the algae on their patio/wall then definitely use this product. Follow the instructions and it will work!

Fantastic product, brought this product to try on Indian sandstone works really well and removed 95% of marks .
Would definitely buy again when run out .

We only had small amount of dried concrete on new patio, this product worked amazingly well.

Good stuff, delivered quickly and safely. Thanks!

Delivery service good and the product removed the rust stains and grey spots perfectly. I was nervous to use a caustic material on my new light grey paving but was very happy with the result.

Didn’t remove the grout resin at all! Complete waste of time and money.

Fab stuff, worth the hefty price tag as it does just what it says on the bottle and quickly too! Saved my patio. 😬

Did exactly what it said on the tin it cleaned off rust spots a test definitely use again

After having a realy bad experience with a firm that layed our silver indian stone . To get the excess cement mix off the slabs they had the bright idea to use a strong acid . What a mess , this fetched out the iron oxide in the slabs turning them a horrible yellow they then refused to accept blame and even said it was the firms fault that supplied the slabs . I then had a look at utube and rob parkers best rust remover was mentioned, even though its not the cheapest we thought we would give it a go because the reviews were good . Well we must say a big thank you Rob parkers best rust remover did what it said on the tin. P&p bit excessive but well worth getting our slabs back . THANKYOU ROB PARKERS BEST RUST REMOVER.

Great product, works well

After the builders had left my newly laid Indian sandstone a complete mess with cement ingrained into the stone I was at a loss as how to clean this given the general advice not to use brick acid. There seemed to be very few alternatives on the market until I came across this product. Having pressure washed it twice to no avail (prior to using the cleaner) I must admit I was a little sceptical that anything other than a really strong chemical based product would clean the stone. However after having applied two coats the stones have gone from a generic white powder colour due to the cement to having their natural colour restored. There are still small traces of cement but the results were amazing.

Unfortunately this product( algae cleaner ) hasn’t lived up to expectations. It’s coverage was very poor
On one part of the site it said a bottle covered 25 m sq
On the bottle it said mix 250ml bottle with four litres
On site it said 250 ml 1:10
It barely covered the patio. And three days in I can see no difference at all. Really disappointed

If your reading this it’s probably because you have been as stupid as me, fear not my fellow sufferers! I put an acid based solution all over my new sandstone flagged garden in order to remove bits of cement, when I see it wrote down now I feel even stupider!! Anyway after 2 days the majority of my flags had gone a rusty orange colour (acid stuff had brought all the minerals to the top allegedly) I searched the net and found Bobs product, after a trial on one flag It didn’t seem to work so I had to increase the ratio to 3 part solution and 10 Part water (I used a plastic cup, water, and a shot glass Solution, and a paint brush) the rust colour magically disappeared On 90 % of my flags, I was so happy!! Albeit it didn’t work on every flag but definitely reduced the orange rusty effect nonetheless.
Read the instructions, only do the flags that have the rusty effect on.
I returned an unopened bottle and got a refund super fast.
Don’t use any type of acid on any natural stone is the lesson I’ve learnt this time.

This product works very well. Tried a test patch first then as per instructions. I used it on Indian sandstone as was pleased with the results. I was a little cautious at first but there was no need to worry. It left no adverse stains.

Excellent product. I was a bit worried initially as it seemed to cause a brown stain on the stone steps but once it dried and had lots of water on it the stains vanished!

We ordered this to use on our Indian stone patio. The guy who laid it cut flags near the ones he'd already laid, didn't clean up and It left a horrible residue which no amount of power washing would clear. The flags looked great when wet but always looked whitish when dry.
We were a bit sceptical as to whether ConClear would work but the result is great. We needed to do it twice but the effort was well worth it.
Highly recommended

My husband used brick acid to clean sandstone patio after laying bringing all the rust to the top of the slabs it was spoilt. I bought rob parker rust remover and it was like magic back to normal I am so grateful, it was easy to use and all done in 20 minutes. Fully recommended

Advice given was appreciate via email; since bought Rob Parkers Best Rust Remover. Excellent choice. Arrived quickly. Many thanks.

Worked a treat,obviously need to follow the instructions to the letter which isn't always easy given the vagaries of the English weather but highly recommend this product for a great finish

Was pleasantly surprised by how well this worked. Had some long standing rust marks on my patio which went with just one application. Would definitely recommend this.
