★ Removes rust with ultra-powerful strength. As this is an ultra-powerful type, it can be diluted up to 20 times depending on the degree of rust.

We are currently not offering cheaper, standard powerful types (up to 10x dilution) that are also sold elsewhere.

★ It is easy to handle, unlike special hazardous rust removers that are like dangerous chemicals.

★ Can be used repeatedly.
The effectiveness decreases with each use. If it is heavily soiled, please avoid repeated use.

★ While there may be more expensive and better products, we are absolutely confident in the balance of price and rust removal capability of this ultra-powerful type.

We cannot accept shipping in empty PET bottles or similar containers that can be prepared for free, as leaks and damage during delivery are frequent and complaints are numerous. We appreciate your understanding.

★ When using for rust removal in fuel tanks, please use the ultra-powerful type with as little dilution as possible.
Diluting it 2 times will reduce its capability by half, and diluting it 3 times will reduce it to one-third.

Please consider the necessary quantity after checking the degree of rust and the tank capacity (if the desired quantity is not listed, please inquire via question, and we can list it for the desired quantity).
