Door and window sealant generally uses silicon sealant. How to remove it after it is dry and hard? Let's try the following tricks together.
1. Apply hot water or hot towel to the hard sealant. After the sealant softens, remove it with hard objects such as a shovel.
2. Wipe with a towel or paper towel with some thinner such as alcohol, solvent naphtha, nail polish remover, banana water, etc. If you are stubborn, try more.
3. Women usually have hand cream at home. You can squeeze some hand cream on the residual glue, then slowly rub it with your thumb, and rub it off after a while.
Solution 2:
1. Wipe with paper towel with some alcohol (it is better to use industrial alcohol), and rub a few more times to clean it;
2. Wipe the paper towel with acetone. It can remove residual gum very quickly and easily, which is better than alcohol. Both of the above are solvents, which are also the best among all methods;
3. Use nail polish remover, which is the same as alcohol and acetone. The effect is also very good;
4. Use hand cream, squeeze some hand cream on the top of the residual glue, then slowly rub it with your thumb, and rub it off after a while;
5. Use banana water, where paint is sold, the method is the same as alcohol acetone.
