Use equal quantities of both liquids and shake well to mix. The spray bottle will give you greater control over the application of the vinegar, which will be helpful when cleaning narrow spaces like grout lines. A spray bottle of vinegar is a convenient natural cleaning solution to have around in a pinch. You won't need to use mucha thin dusting will be fine. Work the baking soda into the grout using your fingertips or the bristles of a brush. For maximum efficiency, proceed in small squares, following the grid-like pattern of the grout a few feet at a time. For particularly bad stains, you can also mix up a paste of baking soda and water, apply it to the grout and leave it to take effect overnight. Together, the two ingredients will start a mild chemical reaction, creating a fizzy foam that will bubble over the grout. Allow the baking soda and vinegar to sit for 5-10 minutes to ensure that it's had time to eat away at the worst of the buildup. This foaming action will make it much easier for the vinegar and baking soda combination to penetrate down into the tiny pores of the grout. To get the most out of the mixture's stain-lifting power, wait until the foaming has died down before you begin scrubbing. Using a stiff-bristled brush, scour the grout and space between the edges of the tiles forcefully. After the vinegar and baking soda treatment, you should be able to lift out even the heaviest stains. Once you're finished, give the floor a thorough rinse using a wet rag or sponge, then leave it to air dry. Special brushes designed for cleaning grout can be bought cheap at all home improvement stores. Alternatively, you might also use a long-handled kitchen dish scrubber. Repurpose an old toothbrush and use it to clean grout. The narrow head of the brush coupled with the long handle makes it the perfect tool for getting down into the spaces between tiles. Scrubbing grout by hand can be time-consuming, but it's without a doubt the most effective means of restoring it to its original color.

Summary: Combine warm water and vinegar in a spray bottle. Sprinkle baking soda along one section of grout lines. Spray the baking soda with the vinegar solution. Scrub the grout clean.

Go to the shallow end of the pool and walk down the steps into the water. Spend a few minutes splashing around and getting used to the water. If you're nervous about being in water try blowing some bubbles to relax. First, take a deep breath. Bend your legs until your face is underwater, keeping your eyes closed. Exhale slowly, blowing out bubbles. This will help you relax. Don't start swimming until you've relaxed. If you swim while you're stressed out you risk injuring yourself or drowning. Try opening your eyes underwater while you blow bubbles. This will also help you relax. Stretch your arms in front of you, keeping your head above the water. Stretch your legs loosely out underneath you. You can keep your feet on the bottom of the pool until you start swimming. Remember to breathe deeply and relax. Don't lie completely flat or stay completely horizontal. Try to find a point in between where your body is almost floating. Make sure to do this in shallow water. If you need to, you can stand up to breathe or float until you catch your breath. Cup both hands by pressing your fingers together tightly and bowing your palm out. Extend your hands one at a time and pull water towards yourself in a scooping motion. You will feel yourself moving forward a bit when you scoop the water. Practice this motion until you're comfortable with it. Some people prefer to scoop water in a downward motion instead of towards themselves. Your hands should be under the water at all times. Your legs will keep you afloat while your arms move you forward. While scooping water with your arms, kick your feet under the water. You can kick in a "bicycle" motion by kicking your legs in circles or a "frog kick" motion by kicking your legs out. Practice each kicking motion and decide which is more comfortable for you. Breathe deeply. Keep your head over the surface of the water to allow you to breathe easily. If you find yourself struggling to swim or breathe, stand up and take a break. If you find yourself straining your neck, keep your head close to the surface of the water. Raise your head above the surface when you want to inhale and slowly exhale while your face is in the water. Make sure you're staying calm at all times. If you're having too much trouble keeping your head above water you need to paddle harder with your hands. If you find yourself getting worn out, either stand up or turn onto your back and float until you catch your breath. If you're having trouble staying close to the surface of the water this means you need to kick harder with your feet. Kicking your feet will keep you afloat but only if you're kicking hard enough. Similarly, if you find yourself moving forward too slowly, paddle harder with your hands. If you're scooping the water towards yourself, scoop the water down instead. You won't go forward as fast but it will help you stay afloat. If you're struggling to do a bicycle kick, switch to a frog kick (and vice versa).
Summary: Get used to the water. Position yourself to swim. Practice the arm motions. Swim using your legs. Alter your breathing technique if needed. Correct swimming problems.
