For removing rust we recommend to use Stromme Cement and Rust Remover, dilution ratio with fresh water 1:1 to 1:4.
For removing a thick layer of rust on the tank top or on the deck the Stromme Deck De-Scaler will do the job.
Depending of the amount of the remaining residues to be removed, we recommend to make small test areas to find the best chemical solution before cleaning.
First make a test on a small area with 1:4, 1:3, 1:2 and 1:1 at different squares to see what dilution ratio will have the most economical and efficient cleaning effect.
