It solved her problems because she also had been using a lot of the adhesives. Doing the hook wash will not hurt anything and will certainly clean things up. The WD40 will disolve the adhesives and crud that builds up from the glues that you are using. It does not suprise me to hear that your tech has not heard of this. WD 40 is used for many things and it is an old trick of the trades. Guess it takes an old dude to remember the old ways. Just ask any young person what 2 bits, 4 bits or 6 bits is? WD40 is not a lubricant, it is a penetrating oil which will free moving parts up but will also dry out pretty quickly. Always clean and lubricate with the proper machine oil after doing the hook washing. I create a large fill design, square, rectangle, circle, doesn't matter. Just something that will allow the machine to run continuously. If you can't create the fill, just pick on a design that will allow the machine to run as continous as possible for a bit. It does not matter which needle is the active needle. Lay an old towel under the sewing arm. Remove the bobbin. Go into Settings and uncheck "All Thread Protection". Lift the pinch lever on the needle you are going to sew on. Slow down your speed to 300 to 600 or so, just so it doesn't want to throw the fluid everywhere. Spray the WD40 into, and all over the rotary hook area agressively. Give it time to disolve, spray some more. Clean the bobbin case with WD 40 also. Use compressed air to blow it dry and then lubricate with sewing machine oil. That's it!!
