Aluminium trailer cleaning

[artie]

I think it's Hydrochloric acid Ive been using to clean the concrete yard and driveway,

I splashed a little on the aluminium checkerplate floor of my trailer and it came up like new.

But before I do the rest of it, I thought it prudent to ask if anyone else has done it and were there any long term ill effects?

Unless the entire trailer is aluminium, hydrochloric acid is not good for any steel parts of it.

Most aluminium cleaners are phosphoric acid, which will be OK if it contacts any steel parts.

If there are laps, parts bolted or stitch welded etc the acid can get in between and they may corrode over time.
