You can tell if it needs resealing by the water not beading up as well, grout gets dirty looking or begins growing mold (black spots). DH seals everything - tiles/grout - with the Miracle Sealants 511 Impregnator. I did not want to change the stone's appearance so we use a sealer only and not an enhancer. Simple Green makes a floor cleaner, and I linked a website below with more: Here is a link that might be useful: green floor cleaners

I'm adding to this thread because it seems like many folks who are posting comments here don't have a thorough background in the toxicity of a wide variety of home remodeling materials. Unless you buy your flooring (wood, bamboo, cork, etc.) from a well-known, long-running green housing material distributor, it is likely that your flooring is filled with toxic glues, sealers, and other chemicals that produce VOCs (volatile organic compounds). Bamboo in particular has a lot of glue because bamboo stalks are so thin (look at a bamboo cutting board to fully appreciate how much glue is needed). I have a MPH degree (Master of Public Health) and one of my areas of expertise is environmental health. I'm currently renovating a new condo apartment and for every material, I had to buy it from a specialty distributor that carefully vetted their product portfolio. The benefit of buying from green supply companies -- living in a healthy home. The challenge of purchasing green, healthy building materials -- cost. Green materials are more expensive. But, if you add up all the costs related to adverse health reactions and getting medical treatment to address them...then cheaper, less healthy building materials aren't so cheap, are they? A good place to start is Green Building Supply (based in Illinois, they have a great website), which ships all over the U.S. I bought cork flooring from them, they're great. Can't recommend them enough. They carry a wide array of building materials including safe paints, safe caulks and sealers, safe flooring, etc. If you want to get advice before a purchase, check out the website, 'My Chemical Free House.' Corinne is a building biologist and her site is filled with awesome tips for choosing safe and healthy building materials. Take good care & stay safe!

Thanks for the replies, and esp. Terri, you Oregonian beauty pioneer : ) emagineer, I also appreciate your research. lynn, maybe we'll get some good 'real folks' feedback on this possibly promising technology. Part of me is very skeptical but there's also the hopeful part... Terri, you have given me an idea -- maybe I should try a bed experience for a few weeks -- it would be less than the purchase and would probably be more powerful? I've found spas around here that have infrared LED beds...I can't imagine that you wouldn't have seen results by this point, though. That's puzzling. And I second emagineer's question: have you noticed any improvement in aches etc.? I remember seeing far infrared saunas being sold for that purpose--maybe this would rejuvenate two birds with one stone? :)

I do not want to know! I don't store things under my bed on purpose, but every time I clean out under it I find dozens of lost toys, socks, calculator, pens, coins, legos, etc. There is only a few inches of clearance and I haven't found a box yet that fits with the lid on. I'd like to store sheets there. Under DD's bed I store her toys. They are in shallow boxes to pull our like drawers. In DS's room he has a trundle bed. In the other boys' room one has clothing drawers the other had shallow drawers like DD, but the boxes are full of legos. I'm domestically challenged, I don't dust anywhere.
