What are they?

Acids are found in several household cleaning compounds: pool chemicals, solvents, wet cell batteries, radiator flushers and other cleaners. Such items may include muriatic acid, hydrochloric acid, nitric acid, phosphoric acid, and sulfuric acid.

How To Identify Them?

Read the label and look for signal words: Caution, Warning, Danger, and Poison. These signal words indicate the level of hazard (caution is the least hazardous compared to poison, which is highly toxic). Use the least hazardous product for the job. Read the instructions on how to use the product and use the correct amount. Remember, you won’t get twice the results by using twice the product.
