Topic tags/keywords: question tablesaw jointer drill press cleaning

Yesterday was the perfect day for spring cleaning… so I decided to give all my cast iron surfaces an new youth!

I bought the Boeshield Rust Free + Boeshield T-9 combo to remove rust & protect my table saw, jointer…

Here is what I got after spraying the Rust free product and waiting 1mn:

Here is what I’ve tried to remove these spraying stains:
- spray again then wipe immediately
- dry wipe for 5mn the same place
- wet (!) wipe then dry immediately
- spray the T-9 rust protection and wipe

Nothing really worked, so I spray some T-9 and let dry for the night. It was very sticky this morning and spent one hour trying to get a smooth surface back by wiping with a lot of clean clothes.

However the spray stains remain :(

Any idea?


PS: the Rust free product indicates that it “works best over 70°”. it was around 55° to 60° when I applied it… could that be the reason?

As I understand it T-9 is basically an emulsification of parafin wax in an alcohol so that you spray it on, it coats evenly and then leaves only the wax after the alcohol evaporates. If the picture above was from the T-9, you may want to avoid pooling by spraying more evenly and a lighter coat—-like spray paint. If it’s the Rust-free, I’m not sure what the product contents are but it could be a similar effect. Once you spray the T-9 though, anything underneath is protected with a coat of wax so you may need to buff it really well to be able to remove the stain at this point.

Thanks JimmyNate,

It’s definitively the Rust-free that caused these stains. The warning says that it contains phosphoric acid and might cause spotting on cast iron. But it’s largely advertise as working for that same material.

I’m looking for some other users of such acid products to see if they spray with a lighter coat as you suggest, or on the contrary, do they “flood” the table…

I have used the rust free and I get the same spotting…. it sucks but it really hasn’t effected the tool other then cosmetically…..

My advice is to cut as much lumber as you can, you will never see the spots through the sawdust. (Half kidding half not)

Kidding aside I too wasn’t 100% sold on the Boeshield products. I personally don’t mind the cosmetics from the rust proof product, I consider it character, but for the T9 I never thought that it dried properly. I may have applied it too heavily but I tried many different amounts and never seemed to get a good result.

Thanks Hrolr, Jcecil,
I guess I have to choose between rust or stain!
And I’m with you Jcecil, I’ve tried different approach to spray T9, but it’s always sticky & not really dry even after 12 hours. Maybe it’s a temperature problem…

I too wondered about temperature during application, both of air and of case iron. I would think though that the alcohol would flash off eventually regardless, but who knows. I am still a fan of cleaning with wd40 and steel wool and a coat or two of paste wax. But I do understand those who prefer the more mirror looking surface gotta be careful of abraiding with both cleaning and with the type of wax. I use good old turtle wax but I don’t mind its minimal abraiding, could use furniture or renaisanse I guess.

this stuff is definitely temp sensitive. i have used in low temps and got the spotting, and used it on a 90+ degree day and the smell alone made me sick and it dired quickly with similar effects. i bought an all natural soy cleaner and it seemed to work fine. not temp sensitive.

green scotchbrite …. rubby rubby … should take that off. then apply a thin coat of the T-9. and ‘buff it off’ to make sure there are no pools of that stuff anywhere.
