Hi Gordon . To de-rust I use a 75% to 25% mix of muriatic acid and water . It dissolves rust fast . Just do it in open air or well ventilated area and rinse with plain water . 👍👍👍👍👍
You could try a plastic tub, like a child's swimming pool (cheap), or a heavier, more durable rubber tub from a home supply place, and do the cleaning in those, then you can pour the water/sand mixture into a strainer to re-collect the media. I always used the free-standing (dry) sandblast units so the sand remains contained. Always got a lot of static shocks though, hahaha.
@@57bagre Some of the things I read said people were using the blaster with a pressure washer that was larger than what it was spec'd for but who knows!
