To know that, first, you have to determine the real cause of the stain in your garage floor. The type of garage covering you use should also be considered. For painted garage floors, the simplest solution could just be the application of a fresh new coat of paint over the problem spot.

While that seems to be a good idea, you need to be sure that the paint coating you'll use would really stick into the surface. Because if it didn't, you'll go back to your old problem - floor stains. And you can make it worse even.

Here is where the range of garage floor cleaners available in the market comes in. Thing is, before you put a coat of paint to the garage floor, it has to be cleaned thoroughly.

Do it just like the very first time that you painted your garage floor. Clear the surface of dirt, grime, and oil. And you'll need an effective floor cleaner for that.

Try to use the pressure washer to clean your floor. It water and regular detergent are able to clean the garage floor, they you're lucky. Try to increase the water pressure to 1200 psi for easy cleaning. For maximum effects, get an anti-grease detergent.

If the floor stains are history, then you won't have to buy commercial garage floor cleaners anymore. If a pressure washer isn't available, you can alternately use a steam cleaner.

If the stain is a stubborn one, you really have to go for specialty garage floor cleaners. You can either make them or buy them from stores. If you don't have time to make one, just head to the hardware shop and make the purchase.

But before using it, take time to understand the product's usage instructions. Buy the most recommended brand so the stain is removed and there's no need to repaint the floor.

To make garage floor cleaners, you'll need an all-purpose detergent. The grease-cutting variant is most preferable. Dissolve it in half gallon of cool water. Add a cup of ammonia. Be sure that your hands are well protected as you combine these chemicals together. Wear overalls too - especially when you are cleaning the garage.

You are also going to need the pressure washer, sponge mop, and some soft cloth for drying up the floor. The air in the garage should circulate freely when you are working inside it to prevent possible suffocation.
