New to me solvent

Oct 22, 2021
Putting some 2 cycle equipment up for storage. Went to fog a cylinder with Deep Creep and put in a shot of Blaster Small Engine Tune Up by mistake. Turned the carbon on the pistol to goo. Took the carbon off the spark plug with wipe from paper towel.

Looked up the ingredients and the usual suspects of naptha and isopropyl alcohol..but had a glycol ether called polypropylene glycol monobutyl ether. Is not supposed to harm metal like ethylene glycol. I will experiment with it, but wondered if others had tried this product, or a product with this cleaner/solvent?
