Q:What causes corrosion of car battery terminals, and what’s the best way to deal with it?
A:The sulfuric acid used in car batteries produces hydrogen gas, which is the primary contributor to corro- sion. Small amounts of gas are released that combine with the heat, dirt, oil and humidity in the air,
which forms the corrosion on battery cables and terminals. If you don't get it off, it can cause problems, such as
trouble starting the vehicle or the electrical supply losing power while you’re driving.
To clean the battery, first remove both terminals with a socket wrench, starting with the negative (black) cable.
The white crystals of the corrosion are toxic to touch or breathe, so wear gloves and safety gear. Use a stiff wire
brush to scrape off all the corrosion from the bolt, cable assembly and the battery terminal. A spray solvent will help
loosen the corrosion. Dry the battery and apply a corrosion-resistant jelly or spray lubricant to the terminals. Reattach
the battery, fastening the red cable first.
Q:My kitchen floor has a loose seam where two sheets of vinyl floor meet. How do I fix this?
A:Use a hair dryer to heat the edges of the seam to make the material more flexible. Peel back the edges and remove any debris with a vacuum cleaner. Mask off the seam with painter’s tape. Brush on Sheet
Flooring Adhesive to the backing on each side of the seam. Press down the flooring firmly, closing the seam
tightly. Use a board with weights to hold the seam closed as the glue dries. Then, use a Seam Sealer Kit to fuse
together the vinyl edges. Seam Sealer Kits typically include a cleaner, applicator, catalyst and sealant.
