Pressure washer
A pressure washer will do wonders. However you do not own one or do not want to rent one, then scrubbing with an abrasive brush and vinegar or watered down bleach will work as well. Use gloves when working with the bleach!
Use a produce called Wet-N-Forget safe for all surfaces
Use a powerful water blaster
Power wash with soap appropriate for pavers
Go to Menards and ask them & they will help you out.
If concrete, muriatic acid, if slate, sandstone, Tenn. Blue Stone, etc. A good scrubbing with a deck brush and elbow grease.
Wet & Forget from Walmart, Amazon and the big box stores. Spray it on let it set and powerwash. I have put this on mossy roof top shingles and let it go over winter-all gone
