I've used Carbona on tons of different stains and it works really well. I've gotten it at Hancock Fabrics.

I use a mix of 50% peroxide and 50% water. Spray on stain and let it set for one half hour, then wash as usual. Works great on old stains too.

Lestoil. Many years ago, my ex-husband was helping his brother change an engine and picked up what he "thought" was a rag to wipe his hands off (they were covered in grease and oil). My ex sil treated her daughter's shirt with Lestoil, then washed normally, no more grease!

Sodium Carbonate A.K.A. Arm and Hammer Super Washing Soda or Pool Shock for those of you with pools. Use 1/2 cup per load. You will be amazed at how clean your clothes are and how absorbent your towels are.

you can also find it in craft stores where the Tye dying supplies are sold - but you'll pay dearly for it.

There's a product that I buy for my husband (and me ) called "Goop" for greasy hands. In fact, I just used it on my DIL'S blouse and it's back to new looking again.

Zout from the Dollar General store (when they have it) or Oxyclean. I just made raspberry jelly and it splattered all over a yellow blouse. I couldn't stop and change so wore it for several hours and it was the next day when I got it to the machine. I first Zouted it and let it sit. Went back and oxycleaned it and threw it in the washer. Took it out and looked it over good before drying it and gone!! The towels I had been using didn't get the treatment and there are blue stains all over them.

Borax or rub a paste of powered detergent and leave in sun to dry...

I'll ditto that - It's my one 'never fail'.

I use the oxy gel stick and it does wonders.

I use Zout or WD-40.
