Liquid Fornula 90 has been a staple of cleaners for years. Liquid 90 dissolves in hot or cold water. It won’t leave undissolved granules behind. Your mixture ratio will vary from 320 to 1 for heavy soil to 960 to 1 for light soil. This product works well for greasy soil and heavy dirt. Buying one gallon is the equivalent of buying an entire case of normal traffic lane cleaner.
