If you want to make a deck cleaner from products already in your home, there are various options. The most common is to use a gentle blend of 1 gallon of warm water and 2 tablespoons of ammonia-free dish soap. You can also mix water with distilled vinegar. Sprinkling on some baking soda can help to remove mold and mildew. You can add oxygen bleach (but never damaging chlorine bleach) to the water and ammonia-free dish soap solution for something a bit stronger. 

Yes, snow should be removed from a deck to protect it from damage caused by moisture and heavy loads. Shovel the snow off of your deck regularly once it is more than four inches deep. Avoid using salt, which can damage your deck.

Yes, Ipe wood is a popular high-end choice for pool decking. It repels water and is naturally slip-resistant. It's not susceptible to mold, mildew, or rot, either, so it lasts longer and is cleaner and more hygienic than other popular decking materials. However, remember that due to its status, it is a very high-cost wood, and you might find that an alternative would serve you just as well for significantly less.

The best direction for a gate to swing depends on its location and purpose, but swinging inward is the general rule. An inward swing is often considered safer, prevents the gate from opening into public spaces like a sidewalk, and may be required by local building codes.

There are exceptions and specific considerations. If your property is on a slope, an inward swing might not be possible. For a deck gate, it's safest to have it swing away from any steps. In a backyard, the direction can be a matter of preference, though an inward swing can be helpful when carrying heavy items like a wheelbarrow into a garden.

Regardless of direction, ensure the gate can open fully without hitting any objects or blocking spaces. While an inward swing is standard, a gate that can swing both in and out offers the most flexibility if your setup allows for it.
