I have a job this coming Sunday to clean a Toyota Dealer. Manager would like to have all the white painted aluminium cleaned, and have some questions that hopefully you guys can help with.
1. Would a 1% solution be suitable for painted aluminium
2. Would I be able to reach the top without having to rent a lift, height is 25-30'
1. Depending on how dirty and strength of SH maybe 1/2%. Adjust as needed
2. You should be able to reach top. You can always zip tie the spray nozzle want to a 20' pole to gain height if needed
3. You probably wont need to agitate.
4. Use final wash afterwards on surface
