You need to be reading up on it. Google is your friend. I know EBC is pretty good for removing soot and I’m sure our friend @EaCoChem has some products that would be effective. If I lived in one of those areas, I’d be learning absolutely everything I could about how to clean, start an Adwords & FB campaign targeted towards within the next few days, write at least one blog post and get it published of how to deal with, problems, solutions, etc. Become the expert. My page on my website about playground sanitizing has had some stupid amount of views past 3-4 months - like 19K from all over the US and Canada, and tons of calls.
It would be well worth your time to take a day off and devote the whole day and then some to getting all of this setup. I truly believe if you did it right and learned the most effective way, that anyone could easily generate hundreds of thousands of dollars in next several months. Would also contact FEMA and some of the insurance companies to see about getting on their lists. The cleanup from all those fires is going to take a long time and there is going to be a lot of money from insurance companies and government entities thrown at it. @Chesebro, @Seandz and whoever else on left coast.
