Hi Guys, just signed up! Looks like a FREAT place for valuable information!

I do alot of driveways and NEVER use any type of detergent to prewash before i PW. Any suggestions on good,plant safe detergent mixes that might speed things up for us? Thanks!

Typically I just downsteam my normal house wash mix. I know some guys post-treat after cleaning but I only do that when necessary.
