Now, some products neutralize themselves ... by eating your stones : Mrgreen:

Elbow oil or high-pressure cleaner (for those who don't fear pressure ...)

The product we are offering you is probably a very strong acid or base ... it attacks and dissolves mineral and organic deposits.

But like that, one cannot know too much. Concentrated bleach is also a bleaching agent ...

Be careful if your stone is limestone, the acid will dissolve it : Mrgreen:

Concentrated bleach is also a bleaching agent.

and which kills bacteria and molds and therefore with bleach, the stone is not attacked, but restored to its initial state by killing and taking off molds and other living beings, which dead, come off in the washing with 'water.
I have done this many times on tombstones with green and black lichens.
If you want maximum action you can add an oxidizing agent for washing stains, large hyperactive bubbles, without damaging the stone. !!!
After dry, we can treat with commercial anti-mold products, much more expensive, to slow their return !!

It is more oxygen which discolours than chlorine which remains fixed in sodium chloride !!
http://fr.wikipedia.org/wiki/Eau_de_Javel
This biocide disinfects thanks to its oxidizing power......
Gaseous chloramines are very irritating. This is why you shouldn't mix bleach with ammonia.
This is the same reaction that takes place when a swimmer urinates in the water of a swimming pool disinfected with chlorine..

Chlorine is released only with an acid !!!
Otherwise, it remains in sea salt !!!

It is not more ecological in English but:
our immune system makes bleach and therefore is not more ecological !!
http://en.wikipedia.org/wiki/Bleach
In response to infection, the human immune system will produce a strong oxidizer, hypochlorous acid, to kill bacterial invaders .......

A recent European study indicated that sodium hypochlorite and organic chemicals (eg, surfactants, fragrances) contained in several household cleaning products can react to generate chlorinated volatile organic compounds (VOCs). [6] These chlorinated compounds are emitted during cleaning applications, some of which are toxic and probable human carcinogens. The study showed that indoor air concentrations significantly increase (8-52 times for chloroform and 1-1170 times for carbon tetrachloride, respectively, above baseline quantities in the household) during the use of bleach containing products. The increase in chlorinated volatile organic compound concentrations was the lowest for plain bleach and the highest for the products in the form of “thick liquid and gel”. The significant increases observed in indoor air concentrations of several chlorinated VOCs (especially carbon tetrachloride and chloroform) indicate that the bleach use may be a source that could be important in terms of inhalation exposure to these compounds. While the authors suggested that using these cleaning products may significantly increase the cancer risk, [7] this conclusion appears to be hypothetical:

* The highest level cited for concentration of carbon tetrachloride (seemingly of highest concern) is 459 micrograms per cubic meter, translating to 0.073 ppm (part per million), or 73 ppb (part per billion). The OSHA-allowable time-weighted average concentration over an eight-hour period is 10 ppm, [8] almost 140 times higher;
* The OSHA highest allowable peak concentration (5 minute exposure for five minutes in a 4-hour period) is 200 ppm, [8] twice as high as the reported highest peak level (from the headspace of a bottle of a sample of bleach plus detergent).


Use pure bleach without other product with, perfumes, gels, etc., which help to release chlorine, much more violent and toxic and especially outside and not in the house, by not having the mania of clean and disinfect everything with these ordinary toxic products at home !!
A little dirt is better for health than disinfecting without stopping, like some insects and spiders than a house full of scented insecticides !!!
Carbon tetrachloride and chloroform are a real poison !!
and we do it with commercial bleach mixed with other products !!
http://fr.wikipedia.org/wiki/T%C3%A9tra ... onnelle%29
http://en.wikipedia.org/wiki/Carbon_tetrachloride
http://fr.wikipedia.org/wiki/Chloroforme
http://en.wikipedia.org/wiki/Chloroform
The haloform reaction can also occur inadvertently in domestic settings. Sodium hypochlorite solution (chlorine bleach) mixed with common household liquids such as acetone, butanone, ethanol, or isopropyl alcohol can produce some chloroform, in addition to other compounds such as chloroacetone, or dichloroacetone.

Thank you for all these clarifications. Bleach is therefore the product of choice for cleaning dirty stone / cement / patio tiles that have never been cleaned in ~ 30 years.

So I'm going to do my tests. La Croix, here we come !!!!!
