Given a bid on washing 237 storage doors - has oxidation. Owner wants them wash so they can apply some chemical themself to help with the oxidation.
Doors are 10ft by 8ft aluminum. When I wet my finger and rub them, the white powder comes off but some of the brown paint comes off too.
How should I bid this job?
Should I use chemical or just water?
Should I have any concerns?
Your advice will be greatly appreciated. Thanks
