pressure washers and sand blasters are high power hoses that use jets of water or sand to grind away the top layer of brick or stone, removing any stains on it.

Use water, preferably from a source that you know is as pure as possible and is natural, like a stream.  If you wish to do some sort of ritual to bless the water, do that.  Take up a soft cloth, dip the crystal in the water and wipe it clean.  If, after a good scrubbing, there is still dirt, well, that's a natural thing, so just live with it.

Dust and sand is picked up from the soil as the wind passes over it.  It's more common to pick up dust and sand when:\n1) it's a deforested area with easy 'soil access' like a desert or plains (it doesn't happen in forests, or on grasslands);\n2) the soil exposed is dusty, sandy, or contains many small particles which can become windborne (it doesn't pick up gravel, or mud);\n3) the wind speed is high.\n\nI don't know exactly about 'abrasion' and 'weathering'.  in common usage, I'd say 'weathering' is ther main category which refers to changes in an object's surface in response to exposure.  Wethering can be caused by UV exposure (sunlight), acid rain, etc etc.  Abrasion is only caused by physical rubbing across things: sandstorms, rivers, etc.  Abrasion is IMHO a subset of weathering.

complain to the health department.  \n\nAlso, I think the city zoning commision (i may be wrong) but there is an agency that can fine them if they do not clean up their property.

yes, the chemicals we use in our cleaning products, personal products, and building products (including inside and out) all cause damage to ourselves and internal systems, and the earth and atmosphere.\n\ni have converted my home to only environmentally friendly cleaning and personal care products.  i try to use recycle products, and i recycle everything i can.  i will one day build a green house, but not for a while$$$$$$$......

you can use white vinegar or wet baking soda.\n\njust put enough vinegar or wet baking soda on the soiled area and let stand for a couple of seconds. it works for me.

it's easy to get physically clean on the outside. To get physically clean on the inside I guess we can take an anti-biotic, like zithromax. \n\nif one doesn't clean the outside the body starts to smell bad, and can become unhealthy.\n\nWithout the anti-biotic, the body has no defense to harmful bacteria.\n\nhow does one get spiritually clean on the inside....one goes to church.\n\nWithout church, the body is open to harmful things in life and needs a church to help with making the right decision.\n\nlet a church be a place of worship (and that's it).

Sell them to a company that shreds them and mixes them with concrete to make highways.  It's good for the environment.

Get it really clean 1 time and then just do a little by little every day and then you won't have to spend a large amount of time on it. Cleaning sucks I know.
