You may leave items on shelves if you are confident that they will not be in the way of any water spray, hoses, or soap.
If this does not work, you can try the same method but with a stronger, store-bought acid or rust remover. For very tough rust stains, you can mix ten parts water to one part muriatic acid. Apply to the stain, and leave it for five minutes before scrubbing out. Do not use acids or vinegar on epoxy floors. [2] X Research source
If the cat litter has not completely absorbed the oil after a day, replace it with fresh litter, and leave it for another day. For bad oil spills, this process can take a few days.
These grease removers can typically be bought at a hardware store.
You can also use powdered laundry detergent. Mix 1/3 cup (~58 g) of detergent with every 1 gallon (3. 8 L) of warm water that you use.
Keep the garage door open as you clean. You can use a broom to push the water out of the door outside. This will help it dry. You may want to start far away from the door and move towards it as you clean. When you finish scrubbing, you will be next to the door. This will prevent you from having to walk across the slippery and clean floor.
Keep moving the spray across the floor; do not let it linger too long on one spot or else it can scratch your floor. Keep your garage doors open when using a power washer so that the water can drain out.
It might be easier if you break up the floor into sections. Do one section of floor at a time. Rent a buffer with a nylon scrub head. These are best suited for concrete floors.
If you do not have a dust mop, you can also use a broom with soft bristles. Sweep up debris into a dustpan, and throw away.
Do not use soap-based cleaners, such as laundry detergent, as these may leave residue behind on your floor. [9] X Research source Stringy mops may leave streaks behind on your floor.
Do not use abrasive or strong cleaning solutions like Comet on epoxy floors.
