If there is standing liquid on your concrete, remove it before attempting any of the above cleaning methods. For small amounts of water, use rags, a bucket, and a mop. For larger areas of liquid, lay down cat litter or baking soda to soak up the water first. If you have extremely large pools of water sitting on your concrete, break out the wet vac and get to work.

You can certainly utilize a pressure washer to effectively clean your garage floor. If you're dealing with oily residue, consider adding a degreaser to the pressure washer solution. Prior to using the pressure washer, make sure to thoroughly sweep the garage floor to eliminate any loose dirt or debris.

Begin the pressure washing process from the back of your garage, which is closest to your home, and work your way towards the front. This ensures that the water and dirt are directed outside. In case you've applied a cleanser or degreaser, it's a good idea to give the floor another pass with clean water using the pressure washer to ensure a thorough rinse.

Whether you need to winterize your pressure washer depends on where it will be stored. If it's kept in a location where temperatures could drop to freezing, any liquid left in the water pump can freeze, expand, and cause severe damage to the machine. To prevent this, you can add antifreeze to the pump. While emptying the machine with compressed air is an alternative, it can be a tedious process and may not remove all the liquid. If you can store the pressure washer in a relatively warm place with no risk of freezing, you won't need to add antifreeze. However, regardless of storage conditions, it is good practice to empty the gas chamber and refresh the oil before storing it for the winter.

If your epoxy application ended up a bit messy and left spills behind, there are several ways to clean epoxy off of a concrete floor. You can use a power washer with at least 3,000 PSI. However, it may be easier to use a scraping tool or an acidic cleaner, like vinegar, to remove unwanted epoxy. 

If the entire floor has epoxy and you want to remove just excess epoxy stains, these methods could still strip parts of the epoxy floor. Move carefully and in small areas to minimize damage, or call a pro for an expert finish.
