With a large number of options available on the counters, with each claiming to perform better than the other, it is a crucial task to select the best pressure washer soap. If you are a newbie, then you will be roaming from aisle to aisle, perplexed in order to figure out the best soap for a pressure washer suiting your requirements.
We have, therefore, listed down and reviewed using our expert’s opinions and customer feedback, to make your selection easy. But even before you rely on one of our listings, we want you to carefully analyze your needs and then make an intelligent buying decision using our buying criteria.
1. Surface Compatibility
Stores are full of different brands manufacturing different types of pressure washer detergents. There are options for cleaning driveways and concrete, and then they have special formulas to clean wooden decks and vinyl siding. You can also find light formulas for cars and windows that can help you clean surfaces without damaging them. Ensure that the pressure washer soap you intend to buy will be able to do justice to the type of surface you want to clean.
2. Cleaning strength
Not only do your cleaning tasks have to face varied surfaces, but they also have to deal with the level of dirt and grime built on them. For more stubborn stains, dirt, and grime, you will have to opt for concentrated solutions that are mostly labeled as Heavy-duty. For lighter-duty jobs, you can be easy on the solutions but definitely tough on stains.
3. Biodegradability
Because pressure washers are outdoor tools, the pressure washer soap can severely harm your plants and pets. Therefore, when you go through the ingredients standing through the aisle, do look for biodegradable options as they are more environmentally safe and do not harm your surroundings.
4. Versatility
Stores have different options ranging from the best pressure washer soap for decks to the best soaps for driveways, however, if you have to deal with multiple tasks, then I would advise you to buy an all-purpose pressure washer soap that can tackle almost all of your cleaning needs.
5. Water temperatures
The pressure washer soaps are meant to use with hot water or cold or sometimes both. For house cleaning you can easily opt for pressure washer soaps compatible with cold water. However, for commercial cleaning, when you need to maintain a certain water temperature to combat tough stains, debris, grease, and other filth, I would suggest you invest in a hot water pressure washer soap.
