Before the acid dries, scrub off the remaining residue with a long masonry brush while rinsing with plenty of water. Leaving the acid on too long may damage your concrete. Mix 1 cup of baking soda, garden lime, or household ammonia in 1 gallon of water (roughly 250 mL in 4 L), or follow label instructions on an acid neutralizing product. Scrub this over the concrete and let sit at least ten minute to ensure that all the acid is neutralized. Pay particular attention to the edges and any low spots in the concrete. At this point, etched concrete should have a uniform texture like medium-grit sandpaper. If the concrete is smoother than this, or if there are still white mineral deposits, apply the acid a second time. Even after the acid is neutralized, liquid left on the surface may leave a white, powdery residue after it dries. Spray the concrete with water, scrub, and repeat several times to prevent this from happening. Pick up the final rinse water with a shop vac or brush it into the gutter. Use a hose to rinse the acid rather than a pressure washer. These can drive acid deep into the concrete. To be safe, test the final rinse water with a pH test strip. If it is below 6.0, there is too much acid and the floor needs more rinsing. (Less commonly, a result above 9.0 means you've added too much basic neutralizer.) If you have any leftover acid solution, pour it slowly into a large bucket filled partway with the same neutralizing solution you used earlier. Slowly stir in more acid and base as needed until the mixture stops fizzing. Once neutralized, you can pour it down the sink or storm drain. Hose off any equipment or clothing that may have touched the acid. If you do not have plans for the rest of the pure acid, you may want to dispose of it the same way. Acid left in storage can be a serious hazard due to corrosive fumes and the risk of spills.

Summary: Rinse thoroughly. Neutralize the acid. Rinse several times. Clean up leftover acid.

The chemical properties in white vinegar break up the bonds in gasoline so that the residue can fade. You can use any type of white vinegar. Pour just enough on your hands for it to cover your palms and fingers. Quickly rub your palms together. Interlace your fingers and massage them with the white vinegar as well. Continue for at least 30 to 45 seconds, though you can rub for longer if you'd like. Once you've thoroughly rubbed your hands together, you can rinse the vinegar off. Put your hands under a running faucet, and wash them with soap and water. Wash them until you no longer smell the white vinegar. Then, dry your hands with a towel.

Summary: Pour white vinegar on your hands. Rub with the white vinegar for 30 to 45 seconds. Wash your hands under a faucet.

Congress and state legislatures have passed numerous laws to protect consumer's rights in the United States. Underlying these laws are the basic rights to which all consumers are entitled. These rights include: The right to choose from a selection of quality products and services that are sold at competitive prices. The right to safety or that products purchased in the marketplace and used as directed will not harm the consumer. The right to information about products so that consumers can make informed choices when purchasing goods. The right to be heard by manufacturers of products as well as by government agencies and courts when raising a complaint. The right to a remedy or redress when a consumer is dissatisfied with or injured because of a product or service. The right to environmental health, which means that manufacturers and marketplaces cannot operate their businesses in a way that damages the environment. The right to service that is convenient and respectful. The right to education about consumer rights and training to facilitate thoughtful and informed decisions in the marketplace. Before making a large or risky purchase, you should consider checking with other retailers to make sure that the item is not less expensive elsewhere. In addition, you should discuss your potential purchase with a trusted friend or family member who has made a similar purchase. You may also consider: Making a budget to determine whether you can afford the item. Deciding what features or services are absolutely necessary and what are unnecessary but costly. Reading reviews online about the product and determining whether the product has been recalled. You can check on recalled products at: https://www.recalls.gov. A warranty is a promise by a seller or manufacturer that they will repair or replace a product if it breaks down within a certain amount of time. Federal law requires that warranties must be available for consumers to review before purchasing a product. When reviewing a warranty or comparing warranties between manufacturers, you should look for the following: Check to see how long the warranty lasts and if anything voids your coverage. Who provides warranty service is it the manufacturer or someone else? Does the company repair or replace the product if it stops working? What repairs or problems are covered? Ask that any warranties made orally by a salesperson be put in writing or you may not be able to get the promised service. Before contracting with someone for professional services such as lawyers, contractors, plumbers or others, you should make sure that they are appropriately licensed before hiring them. Contractors, plumbers and electricians are all required to be licensed by state boards. You can request a service provider's license number and then check his or her licensure status online. You can find links to state license boards at: http://www.contractors-license.org. You check whether lawyers or doctors are licensed through state bar associations or medical associations. The Better Business Bureau (BBB) maintains a list of complaints and ratings for companies. Before hiring a business to provide services, you should review BBB's website to make sure the company has not mistreated consumers in the past. You can lookup companies on BBB at: https://www.bbb.org. When making purchases online, only provide your contact information and credit card companies at trusted websites. When making online purchases, you should look for a small padlock symbol in your address bar. This indicates that the website is secure. Website addresses that begin with "https" versus "http" offer a greater level of security. If you are unsure whether the site is trustworthy, conduct an internet search on the name of the company or website and the words "trustworthy" or "secure." This may help you uncover any problems people had with the website or reviews that the website is secure. You should always request and keep the receipt for any product or merchandise that you purchase. A receipt is usually required to return faulty merchandise or submit a complaint against a business. You should also keep other important documents related to the purchase of goods or services, such as, contracts, warranties and manuals. It is important to comply with the warranty and care instructions of a product. Some warranties will be voided if you use the product in manner that was not specified. Additionally, some manufacturers require that you register your product and/or warranty with them, either online or by returning a warranty card.

Summary: Learn your basic consumer rights. Evaluate large or risky purchases before making them. Ask about product warranties. Check that professionals are licensed. Check business reviews at the Better Business Bureau. Be careful making online purchases. Always request a receipt for purchases. Read and submit a warranty after purchase.
