small black lumps?

Guest

do you have a picture of what your talking about?

I believe your talking about the small black tarry dots that have a little yellow residue?

If so, they are bug poop from catapillers feeding on tree sap/leaves and are a biotch to get off. Being sticky tar like a degreaser would prob work but might need to be scrubbed, auto-parts places sell stuff to get it off your car.

Could be Artillary Fungus

I'm guessing artillery fungus. A few people have mentioned that " magic erasers" work, but I have not had success with using them. They do work, but it's very time consuming. it comes from infested mulch. Each spore needs to be individually scraped.

Wow, Art are you seeing that alot on the Island?

Definitely artillery fungus and I have not been able to remove them either.. We see a lot of it here in MD where mulch filled plant beds surround the home.

we have a ton of it here as well it is on a large majority of homes that use mulch for landscaping. I usually tell and show the customer that this chit just dont come off easilly and if you want me to do it its a 150.00 per hour at a 2 hour minimum. They usually decline.hahaha

Mike, even then, can you actually remove the stain behind?

Tried goof off, it does not remove the stubborn little buggers. How you can get them off is to take a small soldering gun, using a point tip, go around and burn each one. After you cook them, they fall right off. Of course, you better be charging $$$$ per hour for this.

Penn State is actually doing a study right now to determine what percentage of mushroom compost it will take to discourage the growth of artillery fungus in mulch. It is a real problem getting bigger by the year. At this time, the only 'cure' I have heard that will work it total removal of the wood mulch beds. My home is covered in them thanks to our generous use of landscaping beds so I did not have to trim... Now I spend hours chiseling the buggers off my white service van and have given up on the house, windows, white railing on the decks and even the old white cat-- she can't move fast enough anymore.

They are a real pain. Whoever solves this one gets rich $$$

It mentions in Sunbrite''s add, a 60 min dwell time. That's got to be tough to do on vinyl siding. I've used laquer thinner to remove artillery fungus from vehicles. Just do a test spot first and make sure it's a base coat / clearcoat finish on the vehicle.

A customer of mine said he had called Rutgers Science Department to find a way to clean it. They told him if he finds a way he'll be rich.

Wonder i we make some strong-ass roof mix thickened up to molasses and brush it on, wait 15 mins then pressure wash it off would work?, hell SH kills 99.99% of everything! The high dwell time might be enough to penetrate and break down the cellular structure?

thinking for a start

-1cup straight SH 12-15%

-1/4 cup Ammox etc

-a lil hydroxide? TSP or such?

Um, ignore this post, gotta run out to Rutgers...
