Greenhouse fiberglass & algae question
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. |
Greenhouse fiberglass & algae question
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.

But would you do this on a poly covered house? I don't know if polyethylene film reacts with bleach or not, or if you could scrub off any UV inhibitors or other coatings... Just curious. I also wonder if calcium hypochlorite would work as well as sodium hypochlorite... Hmmm.... I bet those 'oxy-clean' type cleaners would work well too, somebody should try that experiment. I agree that the bleach doesn't seem to harm the orchids in any way. It has never hurt any of my plants. I've even been known to put some in my water tank to kill various scummy bits. Cheaper than physan and probably more effective. I probably wouldn't do that all the time, but three or four times a year doesn't seem to hurt. I don't grow pleurothallids...

Greenhouse fiberglass & algae question
I tend to use clear water with a hard stream from the hoes or with a cheap
pressure washer. Stuff comes off pretty easy although I often have to make a second 'spot clean up' pass. If it seems really bad or the crud has been coming back too quickly, I will use between a 1 and 2 percent bleach solution blasted from a hose. I do rise off plants that get wet with the bleach.

Rob Hi Rob Two things where noted on the greenhouse grade of polyethylene film I bought; 1. do not clean with soap or detergents 2.Do not abrade (I suppose that means scrub) I'm guessing the UV treatment is on the surface rather than in the poly. That seems like a dumb idea to me but then they sell more poly that way. Thanks for all the answers Dusty |

I remember our double polycarb came with tear away labels stating only one
side was UV treated. We had to mark each sheet on the outside. It also said that the UV treatment wears off after 10years? So I imagine bleach would not be good. -- Cheers Wendy Remove PETERPAN for email reply dusty wrote: Rob Halgren wrote in : K Barrett wrote: 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.

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 Thanks for replying. No wonder they call you dusty.... K Barrett |
