I have a tank in my living room that has been set up for 4 years. I really need to clean my carpets and am renting a cleaner this weekend. I thought I had seen where someone said not to clean carpets with a cleaner as the chemicals will get in the tank? Is this true? Its not like its being sprayed into the air. Its sprayed into the carpet and then sucked right back up.Any suggestions or cautionary measres I should take?
