Things You'll Need
- Plastic paint scraper
- Rags, dampened with warm water
- Rough sponge
- Vinegar
Instructions
Scrape off the larger amounts of salt residue using the paint scraper. If there is a big enough buildup, the salt may come off in thick sheets.
Lather warm water and vinegar onto the remaining salt and let it sit for about 2 to 3 minutes. The warm water and vinegar mix will hopefully dissolve some of the salt, making it easier to remove.
Gently rub off the remaining salt with the rough sponge,. To avoid scratching the plastic, make sure not to press too hard. You should do this until nearly all of the salt has been removed.
Wipe away any remaining residue--which should now come off easily--with the damp rags. Clean the plastic with another damp rag, giving it a shine.
