    I'm a lawn guy looking for help on my personal home.

    I have some mildew and grime building on the trim of my brick home. What's the best none pressure wash way to go?

    Was thinking a 4:1 water to household bleach spray would work. Spray it, let it sit, and hose it off.

    Any suggestions or recommendations?

    i was always taught to stay away from bleach, being it affects any termite treat put around the perimeter of a home.

    Not to disagree but if that were the case termite guys would put a stipulation in their contracts that would void warranty if bleach was used on the home. No such clause is in my contract with Terminex.

    I use diluted outdoor bleach and house wash all the time on my home. The heavy areas will need a little scrubbing to remove all of it.

    I concur with Russell. Allow the mix to dwell on the trim for 10-15 minutes or so and it should clean up fine. (Don't allow it to dry during this dwell time)

    I would recommend the liquid from the pool store. The concentration is higher and usually contains a little algaecide that will give some after effect too. Always wet the area first and work your way UP not down.
