Cleaning Concrete Pavers

Snookums · 18 Mar 2019 at 11:21

The sun was out this morning and my pavers in the garden needed a good cleaning so popped out and got some Karcher stone cleaner and went at them with my k2 and patio cleaner attachment however they all havent come out clean.

as you can see the back ones have come out fine but the ones around the front the dirt just wont budge, Im guessing the people here before us had something covering the back area so it wasn't quite as soiled as the front.

Anyone got any suggestions for something to get it budge? I even let some strong APC dwell on it for 15 minutes but still no success.

Bleach. Spray bottle if you can, let soak. and rinse. Scrub if needed with a hard brush.

I use caustic soda in a watering can.

I'd just go at them with the lance as opposed to the patio attachment. The rotary nozzle will easily clean them up.

Jayes fluid apparently does the job.
