Black TMPS alloy valve stems
Even though I keep my 442 wheels in good condition with regular cleans the alloy part of the TPMS valve stems turn black and I find difficult to clean off. Tried iron off substances and alu-clean with little effect, anyone having same issue and any recommendations for cleaning back to silver.
