A rinse aid is a liquid which is added along with the detergent to aid in the rinsing process after the wash. The discovery of the rinse aid was prompted by the fact that many times subsequent to the wash the dishes were found to be streaked with water which would leave spots on the surface on drying. The usage of strong detergent for washing, although effective against stubborn food particles, caused the crockery and the cutlery to lose its shine. Therefore, the product called rinse aid was introduced which, on being added along with the detergent, solved all these problems and apart from speeding up the drying process left the dishes free of streaks and sparkling clean. Rinse aids are of different types like the dishwasher rinse aid, the finish rinse aid and the e-cover rinse aid, all of which form an important part of the cleaning supplies for homes as well as commercial establishments.

A dishwasher rinse aid is added to the dishwashing process through the use of the dishwasher rinse aid dispenser. The advantage of a dishwasher rinse aid dispenser lies in the fact that one is able to control the amount of rinse aid which is discharged into the rinse cycle. Since rinse aids are formulated to ensure that there is no residue left on the dishes and that they dry quickly without any streaks of water left behind, they should be bought separately irrespective of the type of detergent being used. This is the reason as to why rinse aid is referred to as finish rinse aid as well. The dishwasher rinse aid is used by pouring the requisite quantity of the rinse aid into the dishwasher rinse aid dispenser and run the rinsing cycle normally. Care should be taken by the user to refill the dishwasher rinse aid in the dispenser regularly every month of repeated use.

The e-cover rinse aid is considered to be a part of the eco friendly cleaning supplies since it is one of the few rinse aids which are manufactured keeping in mind the environmental advantages. The constituent ingredients of e-cover rinse aid are aqua, alcohol, citric acid and butyl d-glucoside and this rinse aid can be purchased in bottles made of polyethylene. Some of the personal advantages derived from this rinse aid are that it prevents streaking, does not leave any chemical residue and also prevents calcium deposits while some of its environmental advantages are that it is made of plant based ingredients, is biodegradable in nature and has the least impact on aquatic life.
