Customer Advice – how to best prepare parts for blast cleaning
We can normally process only fully dismantled components though studs and bushes can usually be left in place. Contact us regarding assemblies or with any questions at all.
When dismantling, be sure to remove all shims, plungers, springs, O-rings, oil seals or other light press-fit or slip-fit parts. Small spigots or dowell pins can either be a tight fit or a loose fit – please remove if loose. If not difficult, also remove ball, needle or roller bearings – however these types of bearings can often be left in place without causing problems.
Our processes will normally remove gasket remnants without too much trouble, but they can sometimes be very tenacious. Long soaking with appropriate softening agents helps but careful handwork is sometimes needed. As it’s difficult to pre-judge, there could be an extra charge, but prior approval is always sought. Even silicone sealant is difficult to remove as it’s resistant to all solvents.
By all means phone for an estimate. We emphasise that the price charged will be subject to sight of the items when received but it’s rare for the price to increase, and you would always be advised first. All handling and work is carried out at your risk.
Extra note if sending by Royal Mail or a carrier
Pack and pad extremely well in a good double-wall corrugated card box! Make sure items cannot knock against each other, so put suitable packing between (ideally wrap items individually with padding before packing in main box). The same packaging will be used to return your items.
Only one parcel has been damaged in transit so far, and we want it to be the last! It is recommended that you use an insured service (Royal Mail’s ‘Signed For’ is NOT an insured service). We can arrange insured collection from you if required.
We take great care with return packing which we charge at £10 to £15 per box (postage or courier service is charged at cost). It takes a quite disproportionate amount of time to make well packed parcels of irregular shaped precious items.
In the very unlikely event of damage (or loss) in transit, liability is limited to the compensation paid by the carrier.
