Adding dish soap to drywall mud is an informal practice that can change adhesion, drying, and sanding, so manufacturer-approved compound should be used without improvised additives.

Dish soap makes drywall mud very smooth, creamy, mud separate pretty easy, easy sanding, bubble-free, tool easy to clean up. But the question is, "how much dish soap is in drywall mud used?"

For a 1-gallon lightweight premixed compound, one tablespoon shop is enough. For a 5-gallon bucket, you can use 4-5 tablespoons of dish soap. You can use any dish soap, choose a good one.

However, you should be careful about mixing soap with mud. Too much mud completely damages natural thickness and adhesive ability.

How can I understand that I use too much soap?

If soap has been added and the mud becomes unusually slippery, weak, foamy, slow-drying, or hard to control, discard the batch rather than trying to rebalance it.

First, you will see the mud is too smooth, and it does not stand in the pan.

Second, it does not stand on drywall. 

Third, and when it dries, it easily peels off because it loses adhesive ability.

You can check why drywall mud peels, I describe in another article.

Dish soap or detergent should I use in the mud?

Do not add dish soap or laundry detergent unless the joint-compound manufacturer explicitly permits it, because surfactants can change adhesion and drying behavior.

How much soap can be used on tapping compounds?

Taping compound relies on dependable adhesion and strength, so adding dish soap or detergent is especially inappropriate unless the manufacturer specifically approves an additive.

Conclusion

For predictable drywall performance, mix joint compound only as directed by the manufacturer and avoid fixed soap-to-mud recipes or other improvised additives.
