Hello:

Was about to rent a pressure washer and try to clean a lot of years worth of
dirt and grime from my deck before re-staining it.

Read a lot about pressure washers on forums, here, and elsewhere, and it
seems like it is
very, very, easy to damage the wood. Have really become scared of doing it,
as I am a rank beginner in using pressure washers.
Certainly don't want to damage the wood any.

Was wondering:

Is there any type of "cleaner" or solvent that is totally safe for a wood
deck, and that might do a fairly
comparable job to pressure washing it ?

Thanks,
Bob
