These above general remedies for Saturn also work for Saadhe Saatee.

The people who do not know Jyotish, or do not know this theory, may use mustard oil everyday in cooking etc as their habit or culture, and unconsciously strengthen Saturn, most of the cases which is a malefic planet causing a lot of troubles and grief.

Note: An used horse shoe and used iron nails from boats are used to appease Shani Devataa (Planet Saturn). But this has to be done with caution. In my personal experience they appear to strengthen Shani than just appeasing him. They do give some troubles besides benefits. The horse shoe, iron nails should be used only after doing specific Poojaa and rituals performed by a learned Pandit (Vaidik priest).

Since dog is considered as the Vaahan of Kaal Bhairav - in one way he is Adhi Devtaa of Shani (Shani is equal to Yam as he does Yam's job in Kaashee). And since he is Ugra Devataa he works only in night, that's why I told this and wearing blue stone needs astrologer consultation, but in general it is also a remedy for Shani.
