My first go at citric acid rust removal

Yes I will then spray inside and out with Duck Oil

A little trash sound for the occasion. New M16 bolts and nuts are sold individually, and in the video a bunch of bolts cost about 100 euros. Heavy rust and a lot of old paint. 24 hours and 5 sessions of hot ultrasound for 30 minutes + rinsing in clean water. When I remembered to update the timer.

What are you doing to protect them?

In the description of the video there is a 3-point recipe.

These bolts will be buried inside the concrete, but not all of them. A little WD40 for peace of mind

Cost you £10 to have those plated at my local! Including removing the rust

My local just does beer etc, crisps and if you're really lucky peanuts.

Mine local plater has a minimum charge of £60 + VAT!

Just used the last of the citric acid powder up. Emptied into an old black plastic oil drum. Derusting a whole load of trampoline fittings plus some of the late FiL's gardening tools.

Fizzing away like a good 'un in this heat. You can just hear it on the video clip (then the neighbour fires his saw up):
