I've been doing a bit of surching for cent masking solutionsfor hypo.. I may have found some thing that is a lot cheaper than what I've seen marketed. And i think it is the same stuff under different guise. I think it is the wax rinse aid the car valiters use. I may be wrong.Any thoughts
Just buy the stuff that’s approved and legal to add to hypo ,it’s safe works well and is a proven product , the money you can make with softwashing is huge why try and save a couple of quid
?? One gallon lasts for ages you only need 300 mm per 20 ltr drum of hypo ,you cannot get much cheaper than that
