After using a metal substance say for example metal tools for quite sometime you will find the metal substance has got rusted. You have to clean the rust to use it again.

If your metal substance is a new one then use of sand and wax can prevent it from getting rusted.

Use of mixture of motor oil and sand can act as a rust treatment for metal tools. Every time after using the tool you can dip the tool into the mixture. It will act as a cleanser for the tool and because of the presence of the oil it will act as coating against rust. This mixture will sharpen the tool a little bit. Be careful while using it. The tool should be of full metal and not a mixture of other elements like plastic or rubber. The presence of sand in the mixture will harm the durability of plastic or rubber. Always try to use the organic rust cleaners for mixed tools. This rust remover is non-toxic so will not harm the material. This mixture is perfect for axe or shovel. Never try to use this mixture to clean complex machine tools.

At home you will find people using lemon juice to clean the rust. They even use Morton Salt for the same purpose. These two substances are effective rust products for household metals. But main disadvantage is you have to clean the metal very well by rubbing it with metal wire wool, cotton or scrubber. This work is very laborious and tedious. That why many people try to avoid it and try to use ready made rust remover products that are available in the market. These readymade products are also very good if you can choose the right product from the right metal because metal can react differently with the ready made product. Sometimes they are even harmful for the metals. So always read the instruction and recommendation before using it.
