Brick Clean around cedar shake Paul??

[bill3752]

Will be using D600 to clean brick on a new home. Trim appears to be cedar, and there a couple of spots of cedar shake siding. Aleady been stained. Will D600 affect the cedar?

Should have no problems if it has already been stained.
If it's uncoated, it may lighten it a bit.
Pre-wet in any case and work from bottom up (as usual) to avoid streaking.
If the shake is below the brick, then rinse it after applying the D600 to the brick
(it's just a precaution against streaking if it does lighten a bit).

Paul, thanks for the input. Went to house today to test some spots. No significant affect in color.

No problem - we did a couple last year that were similar (one with Vana Trol and one with D600)
