1) Buy an antibacterial solution. Pur the solution inside a spray bottle, so it will be easy to distribute the product all over the toy. Then, clean the toy with a piece of cloth.
2) You may use a solution made of bleach and water. Use a rug to wipe the toys.
3) Fill in a bucket with water and dish soap. Put the toys inside, and leave them rest in the solution for a couple of hours. Then, wipe then with a piece of cloth, or put them in the sunlight to dry.
4) For removing long lasting stains, you may decide to use a brush. You can use the previous explained solutions and brush the toy affected areas until they disappear.
I hope these tips will help you, and your children's toys get as shiny as glass!! See you my dear friends!
