I didn't even know these slabs were alternate colours before I started.
An initial power wash took enough grime off to show they were chequered patterned. I then used Sodium Hypo which took 95% if the deep ingrained dirt off.
I opted to use Blackspot Remover for the stubborn stuff. It was completely removing it from slabs while I was still spraying the rest. The picture tells it all.

This is a reorder excellent cleaner, stays clean for longer.The free next day delivery is a bonus

Pink Hand Soap | Silky Smooth Hand Wash

Arrived on time & used at the weekend. I found the product worked really well & my slabs have come up really clean. I did rinse off with a jetwash but really happy with the results. Would definitely purchase again.

Fast delivery

Arrived within a couple of days from ordering which was very good, the product itself is brilliant, my wooden garden furniture and stone patio look like new with very little effort.

Product was delivered on time and although only used once it has done a good job. %ltr will last years but works out as excellent value for money

Great product quick delivery

i really love it thank you 😀

The liqui blue and the liqui rinse do exactly what it is intended for. Keeps the caravan toilet clean and smelling great. The blue takes away any odours in the container and the rinse leaves the bowl clean and smelling fresh. Great products.

Having used Hypochlorite 9.9% previously, I would fully recommend it for cleaning patios and and any other hard surface. It will remoe many stains and marks leaving the are like new.

This product is amazing and highly recommended! This has been washed by a pressure washer after and I finished the whole bottle, but the black stuff are so much easier to wash with it though.

I'm very happy with these Jerry cans. We use them for essence in saunas and steam rooms. Great price and service. Thank you.
