Moin, with an older golf (2012) “gammel” the wheel screws always tight. Of course, I pull on with torque wrench and matching NM. However, my guess is that there are just too much contaminants in/dran. I always brush the wheel screws with a wire brush. However, now I also wanted to “clean” the thread. Can you give me tips whether such things: https://www.amazon.de/KS-Tools-3400065-Messing-Wire%C3%BCrste-10/dp/B014ECBVRA/ref=pd_sbs_2/258-0388587-8683334?pd_rd_w= Lp859&pf_rd_p=dd7cdb0d-7d18-43ba-a06d-a9f4cc6bae51&pf_rd_r=M31C9HQSDFNFKA4TS7WN&pd_rd_r=a396ad72-37d1-4e91-a266-cf624ca8a227&pd_rd_wg=qshGQ&pd_rd_i=B014ECBVRA&psc=1 is enough to get the thread “clean”? Or should it not be brass (too soft?)? Is it worth buying new wheel screws? Thank you and your regards!
