If you are cleaning large items such as furniture, a bucket may work best. For smaller items, a spray bottle may be more useful. If you are cleaning outdoor wrought iron furniture or railings, it may be easier for you to use a garden hose to rinse these items. If you have access to a hose, you’ll only need to fill one bucket with water. [2] X Research source

If your wrought iron item is made out of multiple materials, such as a bench with a wooden seat and iron sides, you may not be able to isolate the wrought iron. If this is the case, clean carefully in the places where the two materials meet. You can also try wrapping the non-wrought iron parts of your piece in plastic wrap.
If you are using a spray bottle, spray the sponge or cloth with your cleaning solution until it’s thoroughly dampened.
Remember that if you are washing your wrought iron outside, it may be easier to rinse with a garden hose. If the water in your bucket becomes excessively dirty, you may want to dump the dirty water and refill the bucket with fresh, clean water.
Phosphoric acid comes in both sprays and gels. No matter which product you use, be sure to protect your hands and face from the material. Use rubber gloves, a mask, and eye protection when applying.
If you’re cleaning outside, check the weather before you start the waxing process. You don’t want it to rain on your item before the wax is dry.
