I use bleach at the rate of 1 tsp per gallon in a hose end sprayer,
wet down the surface I'm trying to clean and then brush it off. On my
twinwall I use a soft cloth, and have had no damage, on teh walkways
and benches and walls I use a plastic scrub brush. Rinse again with
the bleach from the dial n spray and I'm done.

No, I don't try to avoid the plants when I do this. No, I don't kill
them. I just move them as needed so I can get to the surface I intend
to clean so I don't elbow them off the bench. Yes, they do get wet.
If I feel guilty about thisI hose them off after I'm done, but really
I don't feel guilty very often. *G*. Yes I try not to get my
pleurothallids wet. everything else is treated as above.

I know this isn't an orchid question but it's related I think.
I'm asking before trying something.
How can you clean algae off of fiberglass without damaging it?
Would bleach work?
If not how about one of those bath room tile sprays.




Thanks
the bleach idea worked like a champ only I used a plastic sponge. one wipe
and rinse and it was gone. Did the underside of the roof with a dollar
store spung mop also.
on your fiber glass question the old stuff had the UV inhibitor built in
but the new stuff is coated like poly which I think is a rather dumb idea.
If you live near an airport like me you have to wash the soot off the roof
at least once a year (I use my car washer and soap for this.)

thanks to everyone
Dusty
