Have only had my '99 acid washed once approximately 6 years ago.Haven't hauled anywhere and now only occasionally to haul to get them shod.The place I took it to no longer acid washes and I really don't want to haul 100 miles or more one way to get it done.What do the do it your selfers use?Prefer a citrus based product if available for safety ThanksPS not sure why my sentences are all running togetherPosting from cheap android phone
