What the sprays do
The CRC example is a battery cleaner in a case of 12 packs, with 11 fl oz per can and 132 fl oz in total as listed. Its bullets state corrosion removal, acid neutralizing and an acid indicator that alerts you to leaks, and it suits terminals, posts, trays and cables. The WD-40 example is a single 13.3 oz aerosol can of contact cleaner that dries fast and leaves no residue, with no follow-up wiping needed as stated. It cleans battery terminals and motor contacts, and its listing states it is safe on circuit boards, contacts, controls and internal components. Between the two sprays, CRC names corrosion and acid, while WD-40 names oil, dirt, flux residue and condensation.
What the brush set does
The IEGREMAR example is a 3-piece wire brush set with stainless steel, nylon and brass bristles, sized 7 x 0.39 x 0.1 in. The stainless steel brush suits rust removal, the nylon brush suits delicate household appliances, and the brass brush suits removing stains on metal parts without damaging the surface, all as stated. The handles are plastic with a soft rubber layer, and the ends are perforated for hanging and storage. Unlike the sprays, the set uses no chemicals: the cleaning action comes from fine, stiff bristles.
What the listings leave unclear
The WD-40 listing counts 1 item while its Included Components field lists aerosol cans in plural, so the pack count reads as a single can from the title. The IEGREMAR listing states an item diameter of 0.4 inches without saying what it measures, next to a width of 0.39 inches. The CRC listing states no drying time, while the WD-40 listing states a fast-drying formula. None of the 3 listings states a warranty term, so warranty scores zero across the board.

How we scored them
The Solar Score weighs performance, build, value, safety and warranty. For cleaning tools, safety means a stated acid indicator, acid neutralizing, circuit-board safety or a bristle that cleans without damaging the surface; the CRC and WD-40 examples state these, and the brush set states a non-damaging brass option. None of the 3 listings states a warranty term, so warranty scores zero on all sides. How we pick explains the weights.

|---|---|---|---|---|---|---|
| CRC Battery Cleaner 12-Pack | 9.6 | 30 | 21 | 21 | 7 | 0 |

| IEGREMAR 3-Piece Wire Brush Set | 9.5 | 28 | 20 | 21 | 5 | 0 |
