2 Go to a chemical store and buy some oxalic acid.
3. Put oxalic acid in the mouth bottle in a well-ventilated environment and slowly dissolve it with water, do not put a large amount of water at a time, wear gloves during operation, and try to stay away from the bottle mouth to prevent oxalic acid from splashing out and hurting people when encountering water.
4 Turn on the exhaust fan and slowly pour oxalic acid into the pool in batches, pay attention to the person not facing the pool, and be sure to wear rubber gloves.
5 Close the door of the bathroom, rinse the pool with plenty of water after a while, and if the effect is not good, you will find that there is much less rust after a few more times.
Since oxalic acid is acidic, it can react with rust (iron oxide) to remove rust, if the sieve is seriously corroded, you can consider dilute hydrochloric acid treatment, hydrochloric acid is more corrosive, and the effect will be much better, but it is more dangerous to do so, and do not use it without professional knowledge.
During the above operations, be sure to keep good ventilation, wear rubber gloves, wear cotton clothes and trousers, and it is best to bring goggles, if there is gas coming out, avoid it in time and do not inhale. In case of splashing, rinse with plenty of water and seek medical attention if necessary.
Cleaning with acid is a dangerous operation!! Caution without professional knowledge!!
First of all, let's understand the cause of rust on towel rails >>>More
The bathroom is damp, the temperature is high, and the iron pipe is rusty, so you should first use a wire brush to remove the rust, then brush the anti-rust paint twice, and finally brush the silver powder paint.
Use a small steel wool ball to dip some used waste vegetable oil (such as peanut oil left over from frying), then squeeze some toothpaste on top of it, and wipe the limescale area! Finally, wash it out with water! >>>More
Focus on the problem of treatment, not how to maintain it. >>>More
The bathroom door is rusty on the door shaft, and a few drops of kerosene or motor oil are moving.
