Moss/Mildew Cleaning 50 yr old brick.
 

I have a patio that hasn't been maintained. The bricks on one side are
discolered with a moss/midldew.

Previous posts say bleach or muric acid? Are these still the best
solutions? Anything better out now adays?

Start with a power washer.

watch mortar with pressure washer; Good old Jeyes fluid is good at
killing moss, but thanks to the EC can no longer state so on the tin!

Use bleach first, a garden sprayer makes it easy, bleach will kill mold
acid wont. If you want it cleaner a mild scrubing or powerwasher will
do. If you still want it cleaner then muriatic acid and a powerwash.
after it is clean regular spraying with bleach will keep off the mold.

You might want to check the BIA (Brick Industry) web site.
The Tech Notes have a lot of info.

This is Turtle.

Bleach + Hand Sprayer = Mildew gone.
