0 CLASSICPW 14 Report post Posted March 30, 2008 Wayne is right on the cost from the pool places, it's high. I would love to buy a pallet of chlorine, but I don't have a cool, shaded place to keep it. Chlorine degrades faster that you think. My pool place, namco, is full of idiots. They place their pallets in the front window, in full sunlight. Many times I had to talk to a manager( 18 yr old kid!) to get a refund because I went to a job with a 5 gal jug of "sweet smelling water" I educated them on the reason for this and they moved it to the back of the store. The next year, different manager, back in the window. Share this post Link to post Share on other sites
0 jeffex11 121 Report post Posted March 30, 2008 do you go to the namco in westminster / that is 25 min from my house. I have been using "outdoor bleach" from home depot that is bleach and sufficant for cleaning vinyl siding and some early porch cleaning this march. I use vinyl brite normaly for siding but the bleach is MUCH better at killing the mold. I too don't want to stock the stuff as I mainly do decks so I just buy convienence and price accordingly. I want the 12% stuff to make a mixture someone on this site told me about that was effective for him. I am emphasizing sales of paver cleaning and sealing this year to get the flat work but I still havent given up on roof cleaning since my territory is ripe for the picking. If I get the work I may buy in bulk for cost savings Share this post Link to post Share on other sites
0 MudDuck 20 Report post Posted March 31, 2008 How did that "outdoor" bleach work? I'm doing job to job chems until I get going and was wondering about that stuff but it was high priced if I remember correctly. Does anyone know if it's different than plain bleach?

0 jeffex11 121 Report post Posted March 31, 2008 worked great at 3 to 1 dilution rate on vinyl siding and moldy painted surfaces. be careful of fumes . 3 parts water and 1 part cleaner in a pump sprayer is what I used Share this post Link to post Share on other sites
0 CLASSICPW 14 Report post Posted April 3, 2008 beware of home depot's outdoor bleach. That stuff is expensive versus using normal grocery store bleach. Honestly food lion's bleach is the best buy. Share this post Link to post Share on other sites
0 jeffex11 121 Report post Posted April 4, 2008 I was told of a formula for roof cleaning that needed 9% bleach + soap for the best spray and rinse action. The applesauce formula is simular so I need 12 % to start with to make it happen. I have done some roofs with 6% ( I get mine at food lion too) and vinyl brite and made money but I had to hit the roof with the pressure washer a little too hard for my taste. I backed the nozzel way off the shingles but I still need more power from the cleaner to go after more of this work. Yesterday I powerwashed a house and across the street there were at least 10 houses with black stains on the roof facing north. the home depot outdoor bleach has a sufficant in it as well as bleach. It is expensive but I can mix it 3parts water to 1 part and it is effective so I used 1/2 a gallon to do this house. I bought it for conveinence. Share this post Link to post Share on other sites
0 Rob R. 14 Report post Posted May 10, 2008 I am looking into doing roofs as well, how are you applying this? downstreaming off a ladder or on the roof? If I were to downstream wouldnt it add more water and diluting the bleach even more..How exactly are you rinsing it off? sorry for the newb questions Share this post Link to post Share on other sites
0 814jeffw 71 Report post Posted May 10, 2008 You guys need to get on the roof forum here. It will provide alot of answers to your questions. 9% shouldn't be needed for roof cleaning. Do it under proper conditions and 4%-6% will work nicely. Jeff Share this post Link to post Share on other sites
0 jeffex11 121 Report post Posted May 11, 2008 I found some 10% HTH pool sodium hypochlorite and it worked well on a garage roof I did several wks ago. It was several patches of mold on a 20 x 40 area of the garage and I was able to hit it lightly with a 40 degree nozzle about 8 to 10 inches off the shingle to rinse. It took one final spray of cleaner and it killed the last of the stain. My rinsing setup would need to be better to do more roofs but this was an add on to cleaning the black stains from the gutters. I haven't committed to being a roof guy just yet although I built a website and b & a postcards to promote it if I get better at it. I guess I need a touch more confidence in NOT F'n up someones roof and loosing my a$$. Share this post Link to post Share on other sites
