Front doors difficult to open -is there a fix?

It attracts dust.

and then the dust turns to a layish quagmire and you wind up in the same boat for a different reason.

get it micky moure clean and then get it perfectly dry, hit it with the dry lube and youre good to go once its dried up.

I bet if you get the fast set stuff that if you spray it on it will be all dried up and ready to use before you get the door back together enough to test it.
