When I first got them they were grimy, had unidentified junk in and on them and just plain gross. Since there were 3 I did a little experiment with different cleaners.
|Before inside, no clue what the sticky at some parts and dry in other parts red stuff is. There was white on the outside too. (?)|
|After. All clean!|
If you want to see they experiment come on over to Treasures My Husband Hates.
