Yes, you can use baking soda to clean your water dispenser. Mix one tablespoon of baking soda with one quart of warm water, then use a sponge or cloth to wipe the solution on the inside and outside of the dispenser. For tougher stains and grime, you can also make a lightly abrasive paste of one part baking soda and one part water to gently scrub tougher areas. Then rinse the dispenser with water. 

Yes, cleaning a crawl space is worth the cost. Although it's an out-of-sight area, neglecting it can lead to significant problems like pest infestations (including termites and carpenter ants), mold, and fungal growth, which can cause structural damage. Regular cleaning helps prevent these issues. While hiring a contractor has ongoing costs, the price for cleaning—typically between $0.50 and $4 per square foot—is much lower than the cost to remediate a pest or mold problem. Additionally, a clean crawl space can lead to improved indoor air quality and more comfortable temperatures in your home.

Not cleaning your house on a regular basis can lead to elevated allergen levels, pest problems, mold growth, damaged belongings, and parts of your home falling into disrepair. Consistent cleaning prevents problems that can lead to illness and ensures you’re aware of the condition of everything in your home so you can maintain and repair things as needed.

If you don’t want to remove the sink stopper, pour ½ cup of baking soda and 2 cups of boiling water down the drain. Start by pouring 1 cup of boiling water, then the baking soda, followed by the remaining cup of boiling water. Use caution as boiling water can damage PVC or other plastic piping. Using a scrub brush or slightly abrasive sponge, clean the top of the stopper, and run the faucet to ensure the drain is clear and the stopper is clean.
