Is there a product that instantly removes mildew off of houses other than bleach/Jomax. Here lately I have been cleaning houses with bleach/Jomax and my XJet. Yesterday, I cleaned a house and the wind picked up and took my mix and "tossed" it in the air. You could smell it on the other side of...

Does anyone know how to get rid of dirt dobber stains that are 20plus ft in the air on a side of a house composed of EIFS? Knocking them down is easy w/ X-Jet or red tip from a distance but can't get rid of the stain. Any suggestions?

I have attached some pics of some stains on some park columns I am supposed t oclean. These columns have, at the top, smooth concrete trim that are black, gray and full of algae. In the middle the columns are masonry brick. Then at the bottom they are white split faced concrete cinder blocks...

Can anyone tell me how to interpret the nozzle chart that is in the provided image? And once I understand the chart is it correct that I divide by 2 for my surface cleaner?

How do I reduce my unit's psi? My salesman told me to not mess with the unloader valve as it could damage my pump. Should I just use different nozzles on my wands and surface cleaners or is there another way? Also do you know of a link to a nozzle chart? I did a search and the links went nowhere.

Is there a way to adjust the psi on a surface cleaner? I was told to not use my unloader valve on my pressure washer and instead use my variable wand. That is fine except that I need to reduce the psi on my surface cleaner. Is this possible?

Has anyone ever seen a red stain like the one in the picture? If so, what did you use to clean it with?

I've got a job cleaning walkways where others before me have cleaned. I have noticed surface cleaner ring marks, deep gum removal marks that bascially replace gum with gouged concrete. My question is how to prevent this? Is it more technique than equipment. I've got the equipment but quite...

I recently removed graffiti from a playground park. There was graffiti everywhere and all of it was removed EXCEPT for a stubborn area. That area is a concrete park bench. I applied taganator and tagaway several times but was unable to remove the paint. I'm frusterated that I was able to remove...

I have a job to remove stains from the back side of a shopping center. These stains are in several areas. Some of them are caused by the roof drains going into the parking lot. Some are nasty run-offs from the dumpsters. But there is a certain area (pictures attached) where the stain was caused...

I landed a big job cleaning walkways for a commercial property management company. However, now that I've begun the job they are asking questions about my methods. I'm using a Hot Water Steam LANDA Unit and everything seems to cleaning fine. The gum and tar are popping off and all dirt, mold and...

I recently performed a job where there was minor damage to the concrete walkways. Luckily, the owner is a contractor and didn't care. However, I might not be so lucky the next time. The problem was that there were two 300' stretches of concrete walkways where the concrete was cleaned using a hot...

I have a bid to clean the inside walls of a building. How would you propose to pressure clean the walls without getting water on the carpet floor? Use tarps and shopvac? Also, I know there are wall surface cleaners and wanted to know if that is the special type of equipment needed. Any help...

Does anyone know how to get permission to dispose of waste water in Conroe, Tx (close to Houston)? I've contacted the local and city sewers and they basically have no idea what I'm talking about. If I get a permit from the state to be a waste hauler do those sanitary sewers have to accept me...

Has anyone ever heard of special equipment that cleans parking garages with 6,000 to 10,000 psi. Bascially, a guy told me of a company who pulls up in a truck ($250,000) and runs hoses through the garage that cleans the garage and captures the water at the same time. This truck apparently isn't...

I just got through cleaning someone's gutters and had some problems. I used Simple Green on the gutters and it worked great or so I thought. I even tested it out on a smaller area and it worked fine. On the bottle it says it can be used for aluminum and painted surfaces which is what gutters...

I cleaned a pebble stone driveway and am not to happy with the results. The area I cleaned is not as dirty as it was but not the same color as the clean parts of the driveway. The dirty areas were places where water puddled together. Is pebble stone the same type of clean as concrete or is there...

I am looking to get a job removing graffiti but before I take the job I wanted to test an area with some new product I bought, Taganator and Tagaway. I did a "test" job on a white brick wall and had a ghost left over. Please view the attached image to see what I'm talking about. After that I...

I am about to go after a roof cleaning job and want a little education. What is the frequency for roof cleanings? If someone wants a clean roof and there is only shading and dirt but no algae or moss do I clean with just light pressure once a year? And if covered in algae or moss do I clean...

I just got my first roofing job. I am new to this business and am hesitant to take the job. I have no help, hence nobody on the ground if I am up on the roof. Can I do this job without help? I have a 24ft. telescoping wand and the pitch of the roof is steep enough that I might have to be on the...
