I think you should be able to easily spray a clean clear non toxic solution on it. Then the mold would just disapper into a fine powder that you sweep up. The removal needs to be easy, not toxic and not hurt the environment or people will not buy it. It should be organic as well.
(This is what I am yearning for) . . . see sample ad below.
Got mold in your shower tile grout? Sick of using scouring powder and a toothbrush, and spending the whole day scrubbing? You are in luck. The Clorox family now offers you TILE PEN. It has a roller tip that dispenses a thick bleach gel on the places where you want it (grout mold), and not the places that you don't (your shirt). Just trace over the grout with the pen and leave. Ten minutes later, a quick rince and viola! CLEAN GROUT THAT YOU COULD KISS!
Every spring, I have green algae all over my vinyl siding on my home. It's really bad in shaded areas. In the past, I would scrub it with a scrub brush and it took me days! Now I get out there with a bottle of Clorox Clean-Up, spray it on the vinyl siding, wait 5 minutes and wash it off with the hose. The only problem now is that my hand gets tired of squirting the entire house, so my idea is to put Clorox Clean-Up (for Vinyl siding) in a bottle that attaches to your hose. Just attach the new idea onto the end of the hose, turn on your hose and it squirts directly onto the house and VOILA....Clean home!!
I don't have a picture of the bottle because you haven't made it yet!! LOL
Make a mold catcher with a couple of filters,and a dehumidifier/and moisture controler. could use ion technology. It should plug in on a wall near a GFI. uses for Bathrooms, changing rooms, laundry rooms, mudd rooms ect. Not only will it catch mold but also clean the air of other hazards. it will freshen the rooms scent as well. The filters can be changed. or if using ion technology you can just wipe it clean. Use force air through it.The filters catch the mold and other hazardious things in the air. the air goes through it and comes out smelling fresher with scents that could be inserted into the mold catcher as well.
