What can it clean, you ask? It’s made to clean dirt, grime, and the silvery color that decks tend to go after being subject to various weather elements for years.

If you have a pressure washer, choosing something that can go straight into your power tool is a good idea. This All-In-1 pressure washer cleaner from Zep is an awesome option.

It’s an all-in-1 formula, so while it works for decks, it’s also great for outdoor furniture, vehicles, siding, patios, driveways, and more surfaces. Considering how low the cost is per fluid ounce, combined with the product’s versatility, this is a very wise investment for your money.

It’s also a concentrated formula, so one gallon actually equates to 26 gallons of cleaner once you dilute it.

What can it clean? All kinds of stubborn stains, including those caused by mold, mildew, and algae. These can be tough stains to remove, so finding something that works well is always a blessing.

Although this is suitable with a pressure washer, you can apply it manually. So, if you don’t have a pressure washer, don’t veto this product yet.
