WHY USE BIO-ENVIRO MULTI-PURPOSE CLEANER? All natural products replace harsh conditions and harsh chemicals, they prevent adverse health and ecological effects. They are just as if not more effective than traditional chemicals. All of the active ingredients themselves are biodegradable, just as mother nature has given us them, so they are readily absorbed back into nature. Here is a product that has been effective in most cleaning situations. You simple just need to either spray on the diluted general cleaning spray and wipe with a cloth. For porous surfaces or extremely dirty use a brush then wipe with a cloth. Bio-Enviro is extremely diverse: Glass 1 to 256 (one ounce to two gallons of water), All Purpose 1 to128 (one ounce to one gallon of water), Heavy Cleaning 1 to 64 (two ounces to one gallon of water). No product on the market can come remotely close to this pricing or the small amount of product used. We do also offer a Ready To Use Non-Concentrated Formula for those of you whom prefer to have the product ~ Ready to Use
