By the way, again, three weeks after the car's roof and saw a car wash and stain the cement of a waterfall and badly ...
Hydrochloric acid can remove the rust I wonder how can I get the order, Naver search, google ...
=> Go to pharmacies for cleaning acid (hydrochloric acid concentration 10%) decided to buy a wipe.
The bottom line ... Is the very best!
To erase the rust stains on the cement was poured the acid cleaning. This is happening in the foam cement stains, water is left standing, they roll ttoreureureu (rolling over) ... Bubbles and water using a tissue, please wipe them well!
Even if cleaning with hydrochloric acid, iron or rubber is not a problem at all. Wearing rubber gloves when working is essential. Wearing rubber gloves, ignoring that the mean time working in the hand will melt the protein. When you are finished, please wash with soap, hand and rubber gloves.
hydrochloric acid and alkaline cement (cement, paint, stains, including mixed) that meets the neutralization reaction of water up happening.
Neutralization reaction occurs at high temperatures because the water vapor is part of the fly.
After reaction, the tissue to clean the stains left my deal. Easily cleared.
Finally, wash the surface evenly sprayed with water hoses, please.
If hydrochloric acid on your clothing, then wash, but whenever a bullet hole bigger.
Be careful when you wash the surface!
Continue to now, cement mixed with water falls from the ceiling of the garage, do not worry ~
A 400ml bottle of hydrochloric acid for clearing which pharmacies sell amounts to 1,000 won in South Korea (i.e. USD $ 1 is enough).
Have a happy car life!
