- Freezing Protection: Check the low-temperature rating like -50°F or -75°F. This shields pipes from freezing and breaking. Lower numbers mean more cold defense for safe storage.
- Safety and Toxicity: Go for non-toxic formulas free of harmful chemicals. These keep people and pets from harm if touched. Bisphenol-free options protect the skin and environment too.
- Biodegradability: Pick biodegradable types that break down in nature. They use plant-based parts for eco-friendly use. This choice helps if spills happen outdoors.
- Compatibility: Make sure it fits RV, boat, and pool systems without harm. Look for universal designs that work on metals and plastics. This ensures long use without breaks.
- Ease of Use: Choose ready-to-use styles that need no mixing. Pour them straight into lines for quick setup. This saves time when winter comes.
- Quantity and Packaging: Buy in gallons or packs to match your needs. Big sizes like 6-gallon jugs cut costs on large jobs. Check for easy-pour bottles for mess-free pouring.
