Follow the below steps:
In the industry, people usually use this solution because its cleaning ability is outstanding and the execution time is short. Machinery and equipment are available leading to reduce the cost of labor.There are two kinds of sandblasting to treat the metal surface including:
Wet sandblasting: it will blast into the metal surface with a mixture of water and clean water with high pressure. The advantage of this method is to handle large rust film. This treatment does not cause dust, but the metal surface will get wet and need to dry before starting to repaint.
Dry sandblasting: Blast into metal surfaces with a mixture of water and clean sand with high pressure. This method helps to treat the metal surface well but causes a lot of dust. It is relatively eco-friendly to use sandblasting technique for large areas. Although this technique needs some specific equipment, in case you are experienced in sandblasting, you can rent the equipment to finish up the job.

In this step, you have to notice that the items are coated evenly. You keep the blaster from six to twelve inches away.
But wait, here are some tips you should follow to get better results.
First, you ought to take advantage of a standard blast pot to reduce the amount of media because it is easy for soda to produce clogs.
Here’s the deal, your standard blast pot offers the best results when the pot valve can control the flow of abrasive.
You should think over a wet blast injection because soda blasting releases more dust than traditional blasting. When you use a wet blast injection, you have more opportunities to pump water to limit the dust.
Many people believe that normal soaps or detergents can also totally remove adhesion paint. However, this statement is not true. Ordinary soaps or detergents only help you clean new, short-term staining paint. As for paint staining on the metal for a long time, you need some substances to remove paint from objects. Using chemicals is the fastest method to remove paint from metals, especially iron since it can effortlessly break down and soften the paint adhering to the metal pieces.However, this dangerous method is likely to have detrimental health effects on users. For paint staining on iron when it has been hardened, people quickly find a way to remove it with a strong liquid or chemical detergent. There are many kinds of chemical paint removers including liquid, aerosol. It is suggested that users should read the labels before making a purchase to choose the method you like best.
In fact, the chemical solution is a common option. Liquid removers are best for small piece of items because they dry quickly. Besides, aerosol is able to cover a large item in a short time. People should prepare some certain items to remove paint from metal:
Follow the directions on the paint remover:

An easy and fast fashion to remove paint from small metal items is to use baking soda combined with boiling water. Baking soda is a non-toxic paint removal. This is the reason why users should try using a mix of baking soda and boiling water to remove paint. This method is effective when applied for metal hardware like hinges and doorknobs. The abrasion of the baking soda removes the paint.The paint on those hinges or doorknobs is removed without comfortable fumes created by paint removal products. There is a wide range of baking soda available. Baking soda is considered to be a friendly cleaner, which is safe to remove paint without releasing harsh toxic chemicals into the environment. In case you do not want to expose yourself to possibly hazardous chemicals, removing paint with baking soda is a great method. Prepare some equipment and tools for this technique:
Conduct the process based on following steps to remove paint completely:
Step 1: Cover a large pot with one quart of water and put it on the stove. Be sure to use an old pot that you can dispose of because it is dangerous to reuse.
Step 2: Then, add the 1/4 cup baking soda and let it sit in the pot bottom. Make sure not to stir the baking soda into the water.

Step 5: Utilize an unused toothbrush or cloth to remove any leftover minor paint on the items.
Note: When soaking items in low boiling water, do not allow them to touch each other or the sides of the pot.
Based on using baking soda, I will introduce you the new technique called “soda blasting”. “Soda blasting” method can remove paint from any sturdy surfaces, in particular metal. Soda blasting is the technique in which people blast baking soda onto the metal items surface by compressed air. This technique is eco-friendly and more effective and safer than sandblasting. Despite the different names, you can still apply the steps in sandblasting in this technique.Renting the tools for this kind of cleaning is easy because they are always available. The equipment used in soda blasting is soda blaster, which makes use of sodium bicarbonate or baking soda. Baking soda is softer than materials used in sandblasting including silicon carbide or aluminum oxide. The process is so gentle that it removes the paint on the metal items without harming the substrate.
FDA approves that soda blast media is a non-poisonous, silica-free non-sparking, non-combustible, environment-friendly, water-soluble and hard to wear down. These are the reasons why this method is so beneficial. Because of its properties, you can apply soda blasting to aluminum, stainless steel, chrome, etc.
After soda blasting, a layer of thin film is left in the items surface. This layer works to prevent flash rust within a month. Because of this, users have to remove this layer before repainting. You should follow the step-by-step guide to have the best result:
Step 1: Prepare a surrounding area and wear protective items like gloves, goggles, etc.
Step 2: Blow out any cracks with a great flow of compressed air.
Step 3: Using a clean and hot cloth immersing the soapy water to wipe the item surfaces.
Step 4: Rinse, wring the cloth to remove this layer of film.
Step 5: Conduct this process again together with clean water until it’s clean completely.
The cheapest way might be a traditional one, which uses a paint scraper as a paint remover for metal objects. This technique works well on items with a thin paint layer. But wait, because the metal is so vulnerable to damage, this method is highly recommended to apply for iron items only. On top of that, people should combine two methods to remove completely the paint when it is in bad condition.
Combining two methods is the most effective way – use a paint scraper or a wire brush to scrape the paint away on a wide metal surface, then finish with another technique like using sandpaper to handle and scrub the corners and cracks. You can use a cordless drill with a wire brush. This is a good choice if you are shaving on a wide surface. Remember to use earplugs when operating the drill. Make sure to wipe away dirt and paint dust with a damp cloth while working. Remove any remaining paint patches. Use the clean cloth to scrub thoroughly, clean all pieces of peeling paint, sandy soil, grease and dirty marks on the surfaces of the items.
