Product review (1 stars): "Harmful or fatal if swallowed"
Really? You're going to paint a highly toxic product inside your *dishwasher*?!

I was given a bottle of this to touch up my rusty dishwasher, thinking that the rust posed a health concern. After some research, I am much more concerned about the safety of this product than the rust. (Turns out rust is just oxidized iron and safe to ingest in small quantities.)

It says right on the label in big bold letters, "HARMFUL OR FATAL IF SWALLOWED. Avoid eye and skin contact. Keep out of reach of children." Other reviewers have noted that it may wear down and need to be reapplied -- which means it's coming off during wash cycles. It contains Xylene, Methyl Ethyl Ketone and Ethylbenzene, all of which are highly toxic. If ingested they pose developmental and reproductive risks.

Now, chemical safety is all about dosage. Maybe if only very tiny amounts are wearing off, and most of it washes away, you're ok. But do you really want to risk it? What if a bigger bit comes off and gets stuck in a mug?

Just get a new rack. Don't be penny wise and pound foolish with your family's health.
