|
|
| I've run into some yellowish-green stuff (mold, i think) that will not come off, even with a lot of pressure. I especially noticed it along the bottom of one house I was cleaning, creeping up about 8 inches to a foot up from the grass line. I don't know. is it mold? could it be rust? again, it isn't the typical greenish mold that chlorine bleach will take off. Suggestions, anyone? |

Its hard to say without seeing it. I do not know of any mold that will not come off with chemicals and/or pressure. Could be rust, have you tried using rust remover?
Only other thing is I have seen staining around the bottom of houses that have dirt around them with little to no landscaping. It is yellowish staining from rain splashing dirt and mud on the siding. It will usually come of with a soft scrub brush and some degreaser. |
